考虑市场主体价值贡献度的分布式能源交易机制设计
Design of Distributed Trading Mechanism Considering Value Contribution of Market Entities
摘要
Abstract
[Objective]Distributed photovoltaics(PV)has developed rapidly in recent years under the guaranteed purchase policy due to the decline in costs.However,unordered growth has increased distribution network operational pressure and created new issues.Thus,an efficient,enforceable market-oriented mechanism is urgently needed to guide healthy PV industry development,coordinate flexible resources,and promote local consumption of new energy.To reduce operational and management burdens on market organizers and participants,this paper proposes a new event-driven two-stage distributed energy trading mechanism for distribution network markets.[Methods]First,the baseline operation state of the distribution network is determined via day-ahead pre-balancing,and whether to trigger distributed trading is judged based on line congestion,voltage over-limit,etc.Then,distributed trading is conducted on demand,using price signal to mobilize resources in generation,load,and storage links for optimal distribution network operation.To incentivize market entities to support system operation through trading,a value contribution evaluation method is proposed based on the"who serves,who profits"principle.Sensitivity factors measure each entity's contributions to improving voltage quality and alleviating line congestion.Market entities'contributions can serve as the basis for allocating incentives for delaying distribution network investments,boosting their willingness to participate.[Results]Case analysis using the modified IEEE33-bus system verifies the mechanism's feasibility and effectiveness:in the pre-balancing stage,midday PV over-generation caused branch reverse power overload,and evening peak load led to low voltage violations.after market activation,all violations were eliminated.PV curtailment decreased by 64%,improving consumption rate.With fewer adjustable resources,system improvements diminished and curtailment increased.[Conclusions]This mechanism addresses the practical issue of distributed PVs failing to perceive market signals,while deferring distribution network investments,enhancing utilization of existing equipment,and providing new ideas for future transmission and distribution pricing.关键词
