摘要
虚拟电厂(VPP)内参与合作的分布式能源(DERs)往往分属不同的利益实体,实现VPP收益公平合理的分配至关重要。基于讨价还价博弈理论,通过效用函数反映风险厌恶程度,综合考虑边际贡献、间歇性电源的预测能力、平衡市场的惩罚力度等因素量化谈判力水平,从而建立DERs联合参与短期能量市场的收益分配模型。通过对VPP的实际算例分析,验证了所提模型的可行性与合理性,该模型可有效评价各DER的特性,保证分配的相对公平性和联盟的稳定性,并可对DERs行为形成正向激励和引导,提高经济利益。
The cooperative DERs( Distributed Energy Resources) in a VPP( Virtual Power Plant) usually belong to different interest entities,so a fair and reasonable profit allocation of VPP is crucial.A profit allocation model of DERs' joint participation in the short-term energy market is built based on bargaining game theory,which uses the utility function to reflect the degree of risk aversion,and comprehensively considers the quantified bargaining power levels of factors such as the marginal contribution,the forecasting accuracy of intermittent power generation,the punishment strength of balancing market,etc.The feasibility and rationality of the proposed model are verified by the actual case analysis of VPP.The proposed model can effectively evaluate the characteristics of each DER,guarantee relative allocation fairness and coalition stability,form a positive incentive and guide for DERs' behaviors,and improve economic interests.
