Modern power grids face profound challenges in scheduling massive,heterogeneous demand-side resources(DSRs),whose collective behaviors often lead to systemic unpredictability and scheduling inaccuracies.Traditional methods,often based on simplified models,struggle to manage this emergent complexity.To address this gap,this paper introduces MetaGrid,a novel digital-twin-enhanced World Model framework designed for proactive and prescient DSR scheduling.The MetaGrid architecture is composed of four integral,closed-loop building blocks:a General Simulator for multi-path deduction,a Situational Perceiver for holistic cognition,an Intelligent Decision-Maker for autonomous optimization,and a Unified Verifier for ensuring trustworthy iteration.By integrating principles from complexity science with data-intensive machine learning,MetaGrid creates a high-fidelity metaverse to model and manage DSR ecosystems.The framework’s core capabilities are demonstrated through an energy storage system scheduling case,where an intelligent agent,guided by the World Model,learns to autonomously balance real-time electricity costs against physical battery degradation constraints.This preliminary validation showcases MetaGrid’s potential as a powerful tool for navigating the complexities of future energy systems,transforming scheduling from a reactive control problem into a process of continuous,adaptive learning. 展开更多

With the rapid increase of distributed photovoltaic(PV) power integrating into the distribution network(DN), the critical issues such as PV power curtailment and low equipment utilization rate have been caused by PV power fluctuations. DN has less controllable equipment to manage the PV power fluctuation. To smooth the power fluctuations and further improve the utilization of PV, the regulation ability from the demandside needs to be excavated. This study presents a continuous control method of the feeder load power in a DN based on the voltage regulation to respond to the rapid fluctuation of the PV power output. PV power fluctuations will be directly reflected in the point of common coupling(PCC), and the power fluctuation rate of PCCs is an important standard of PV curtailment.Thus, a demand-side management strategy based on model predictive control(MPC) to mitigate the PCC power fluctuation is proposed. In pre-scheduling, the intraday optimization model is established to solve the reference power of PCC. In real-time control, the pre-scheduling results and MPC are used for the rolling optimization to control the feeder load demand. Finally,the data from the field measurements in Guangzhou, China are used to verify the effectiveness of the proposed strategy in smoothing fluctuations of the distributed PV power. 展开更多

An effective modeling and optimization method,which takes into account source-load-storage coordination,and full-time collaborative optimization within and outside micro-grids,is introduced.Considering the operational conditions of various resources and their interactions,an energy management model for microgrids is proposed aiming at maximization of renewable energy utilization and minimization of overall system costs.The model is suitable for both real-time pricing and time-of-use mechanisms.In microgrids,demand response and economic energy storage dispatch are introduced to enhance selfcoordination and self-balancing ability among different resources.Depending on whether there is still an imbalance between supply and demand after coordination within a niicrogrid,trade between it and external microgrids are optimized in a orderly manner by considering different transaction prices and usage rights.Finally,three different schemes are designed,where the Lagrangian multiplier method as well as a co-evolution algorithm are used to solve and analyze different examples,verifying the reliability and validity of the method proposed in this paper. 展开更多

As the global energy transforms to renewablebased power system, the wind power generation has experienced a rapid increase. Due to the loss of synchronous machines and its frequency control mechanisms, the gradual evolution leads to critical challenges in maintaining the frequency stability. Under post-fault condition, the wind power generation has a slow recovery due to the fault ride-through(FRT) control strategy and may cause a larger frequency deviation due to the power imbalance between the supply and demand. Then, the impacts of the frequency deviations would further cause inaccuracy and instability in the control system for wind power generation. Considering the long parking time of electric vehicles(EVs), the demand-side response is provided to support the power grid via load-to-grid technology. Thus, a power-balancing coordinated control strategy of the wind power and the demand-side response is developed. It can significantly mitigate the power imbalance, thereby resulting in the enhanced frequency stability. Finally, the simulation results are provided to validate the power-balancing coordinated control strategy. 展开更多

More demand-side flexible resources(DFRs)are participating in the frequency regulation of renewable power systems,whose heterogeneous characteristics have a significant impact on the system frequency response.Consequently,selecting suitable DFRs poses a formidable challenge for independent system operators(ISO).In this paper,a reserve allocation methodology for heterogeneous DFRs is proposed to manage the risk of power system frequency.Firstly,a performance curve is developed to describe the cost,capacity,and response speed of DFRs.Moreover,a clustering method for multiple distributed DFRs is conducted to calculate the aggregated performance curves and uncertainty coefficients.Then,the frequency security criterion considering DFRs’performance is constructed,whose linearity makes it can be easily coupled into the system scheduling model and solved.Furthermore,a risk management model for DFRs considering frequency-chance-constraint is proposed to make a trade-off between cost and frequency security.Finally,the model is transformed into mixed integer second-order cone programming(MISOCP)and solved by the commercial solver.The proposed model is validated by the IEEE 30 and IEEE 118 bus systems. 展开更多

This paper proposes an optimal dynamic reserve activation plan after the occurrence of an emergency situation （generatorransmission line outage, load increase or both）. An optimal plan is developed to handle the emergency, using the coordinated action of fast and slow reserves, for secure operation with minimum overall cost. It considers the reserves supplied by the conventional thermal generators （spinning reserves）, hydro power units and load demands （demand-side reserves）. The optimal backing down of costly/fast reserves and bringing up of slow reserves in each sub-interval in an integrated manner is proposed. The proposed reserve activation approaches are solved using the genetic algorithm, and some of the simulation results are also compared using the Matlab optimization toolbox and the general algebraic modeling system （GAMS） software. The simulation studies are performed on the IEEE 30, 57 and 300 bus test systems. These results demonstrate the advantage of the proposed integrated/dynamic reserve activation plan over the conventional/sequential approach. 展开更多

The main purpose of this research paper is to investigate the long-term effects of the proposed demandside program,and its impact on annual peak load forecasting important for strategic network planning.The program comprises a particular set of demand-side measures aimed at reducing the annual peak load.The paper also presents the program simulations for the case study of the Electricity Distribution Company of Belgrade(EDB).According to the methodology used,the first step is to determine the available controllable load of the distribution utility/area under consideration.The controllable load is presumed constant over the analyzed time horizon,and the smart grid(SG)infrastructure available.The saturation of positive effects during intense program application is also taken into account.Technical and economic input data are taken from the real projects.The conducted calculations indicate that demand-side programs can bring about the same results as the energy storage in the grids with a strong impact of distributed generation from variable renewable sources(V-RES).In conclusion,the proposed demand-side program is a good alternative to building new power facilities,which can postpone investment costs for a considerable period of time. 展开更多

The concept of demand-side management(DSM)was invented in the late 1970s along with the development of many of the frameworks in use to plan and implement it in the years immediately following. It was originally referred to as demand-side load management. It is generally defined as the planning and implementation of those activities designed to influence consumer use of electricity in ways that will result in changes in the utility’s load shape—i.e., changes in the time pattern and magnitude of a utility’s load. This paper describes the evolution it has undergone since its invention and some likely changes ahead. DSM largely originated in the U.S., but is practiced in various forms through the world today. This paper uses U.S. data as examples. 展开更多

Demand-side management(DSM)schemes play a crucial role in managing renewable energy generation and load fluctuations by uti-lizing demand-response programmes(DRPs).This paper aims to provide a detailed overview of DRPs that help microgrid operators to keep costs and reliability within acceptable ranges.Additionally,this review paper provides a detailed economic load model for DRPs based on initial load,demand-response(DR)incentive,DR penalty and elasticity coefficients.This article also aims to guide researchers in identifying research gaps in DSM applications in microgrids by comparing various DSM schemes from different countries and regions in terms of DSM strategies,objective functions and optimization techniques.Furthermore,this study analyses the impact of DRPs on microgrid configuration from the perspective of utilities and customers,considering technical and economic performance metrics.As a result,it can be concluded that none of the studied cases provides models or guidelines for choosing appropriate DSM schemes that consider different consumer interests or load-type features.Furthermore,a few researchers have addressed the features of a modern price-based DR strategy,renewable generation-based dynamic pricing DR,which offers higher customer satisfaction than traditional DRPs. 展开更多

In recent years,the changes in the external environment and domestic development conditions have promoted the transformation of China's economy to one dominated by domestic circulation.In December 2020,the Communist Party of China Central Committee put forward the demand-side reform for the first time in order to prepare China for the new development stage of the 14th Five-Year Plan(2021-2025)and to promote the new strategic deployment of China's high-quality development.Based on the paths and direction of the current 14thFive-YearPlan(2021-2015)tobuild a new development pattern,this paper elaborates on the theoretical connotations of the demand-side reform,points out the bottlenecks such as the unreasonable demand structure in China,the mismatch between the industrial system and the high-level demand,the resulting demand spillovers,the poor demand channels,and puts forward the current approaches to thedemand-sideereform in China. 展开更多

In essence,understanding the relationship between supply-side structural reform and demand-side management requires grasping the interplay between supply and demand.Supply and demand are interdependent and interactive,and their equilibrium determines the equilibrium valuesof microand macroeconomic variables.Focusing solely on either supply or demand,regardless of the time length,is one-sided.To promote supply-side structural reform,China should depend on demand and take a measured approach to its expansion.In the absence of demand,the supply-side structural reform would lose its direction and purpose.Enhancing demand-side management involves delving deeper into supply-side structural reform because the scale and growth of demand,alongside changes in demand structure,are fundamentally influenced by institutional factors.Hence,further reforming the systems and mechanisms that hinder the optimization of demand structure and the growth of demand is precisely what supplyside structural reform should entail. 展开更多

Beginning with increasing effective demand,thedemand-sidereformadvocates for the strategy to expand domestic demand,rectifies distortions in the demand structure,and further aligns demand and supply by reforming the mechanisms for demand formation and regulation,matching supply and demand structures,and easing restrictions on demand.This will enhance economic growth potential and operational efficiency.The demandside reform contributes to developing a super-large-scale market and optimize market functions to form a unified national market.It also helps address significant structural distortions within domestic circulation and move faster to form a new development pattern of dual circulation.As demand-side reform inevitably deals with the vested interests of stakeholders,it presents challenges on par with supplyside structural reform.Therefore,due attention must be given in terms of priority and weight by increasing operational and property household income,transforming governmentt functions,rectifying any excessive market-orientedreforms in certain public service sectors,among others. 展开更多

This paper develops an innovative computational model for assessing the Carbon Emission Factor(CEF)of provincial power systems that incorporates inter-provincial electricity transfers and hybrid generation portfolios combining conventional and renewable sources.A key contribution lies in evaluating how deep regulation of thermal power plants influence the carbon intensity of coal-fired generation and coal-fired generation together with high penetration renewables.Furthermore,the study quantitatively analyzes the role of renewable energy consumption and the prospective application of Carbon Capture and Storage(CCS)in reducing system-wide CEF.Based on this framework,the paper proposes phased carbon emission targets for Guangdong’s power system for key milestone years(2030,2045,2060),along with targeted implementation strategies.Results demonstrate that in renewable-dominant systems,deep regulation of thermal units,load peak-shaving,and deployment of flexible resources such as energy storage are effective in cutting carbon intensity.To achieve the defined targets—0.367 kg/kWh by 2030,0.231 kg/kWh by 2045,and 0.032 kg/kWh by 2060—the following innovation-focused policy is recommended:in early stage,mainly on expansion of renewable capacity and inter-provincial transmission infrastructure along with energy storage deployment;in mid-term,mainly on enhancement of electricity market mechanisms to promote green power trading and demand-side flexibility;and in late-stage,mainly on systematic retirement of conventional coal assets coupled with large-scale CCS adoption and carbon sink mechanisms. 展开更多

Limiting warming to the Paris temperature goals requires a rapid scale-up of low-carbon energy,yet recent experience suggests that deployment is increasingly shaped by delivery constraints rather than by technology cost trends alone.This review synthesizes peer-reviewed evidence on five constraints that repeatedly slow net-zero buildouts:lengthy approval and grid-connection processes;capital-intensive investment profiles that heighten sensitivity to the cost of capital and revenue risk;bottlenecks in critical minerals,processing,and manufacturing;social contestation and local governance that translate into siting exclusions,delays,and cancellations;and modeling traditions that can underrepresent these non-marginal frictions.Accordingly,we adopt an energy-services perspective to examine how demand-side strategies affect the scale and timing of the required buildout.We interpret degrowth as service-based sufficiency,rather than as a blanket reduction in welfare,and organize the evidence using the Avoid,Shift,Improve(ASI)sequence.Across sectors,the reviewed literature indicates that lowering baseline service demand and,in particular,peak requirements can reduce project counts and network upgrades,limit exposure to interconnection queues and permitting backlogs,ease upstream material pressures,and improve bankability under risk-averse finance.We conclude that net-zero pathways are more credible when service provision and demand-side design are treated as core planning variables alongside clean-energy supply expansion. 展开更多

This paper evaluates the role of aggregated demand-side flexibility from public buildings in supporting renewable energy integration and decarbonization of the Slovenian energy system.Using high-resolution monitoring data from over 100 public buildings and the H2RES energy system optimization model,two long-term scenarios are analyzed for the period 2020-2050:a reference scenario without public building flexibility and a flexibility scenario in which public building heat demand is electrified via heat pumps.The year 2020 is used as an internally consistent optimization reference for demand levels and technology availability,rather than as a statistical reconstruction of the observed national energy system.Reported CO2emissions represent modelled energy-system emissions within the covered sectors(power,heat,and industry)under exogenously imposed policy constraints and therefore may differ fromnational inventory totals.The results showthat aggregated public building flexibility affects the temporal allocation of electricity demand and sectoral emission distribution,leading to moderate changes in renewable curtailment and heat-sector CO2emissions while maintaining identical renewable energy targets.The findings demonstrate that electrification and aggregation of public building demand can play a strategic role in supporting national climate objectives and system operation under high renewable penetration.It should be noted that the analyzed dataset,while based on high-resolution monitoring of more than 100 public buildings,is not statistically scaled to represent the full national building stock.The results should therefore be interpreted as indicative of system-level effects of aggregated flexibility rather than a direct national-scale quantification. 展开更多
