考虑灵活爬坡产品的虚拟电厂两阶段分布鲁棒优化运营策略OA北大核心CSTPCD

With the proposed goal of"carbon emission peak and carbon neutrality",large-scale integration of renewable energy into the power system puts forward higher demands for the flexibile operation of power systems.The operation revenue of virtual power plant(VPP)is enhanced by aggregating distributed resources,incorporating flexible ramping products(FRPs)into its operation strategy and participating in multiple types of electricity markets.On this basis,a two-stage distributionally robust optimization(DRO)operation strategy of VPPs considering FRPs is proposed.Firstly,considering the FRP market under high penetration of renewable energy and combining the operation characteristics of multiple types of distributed resources,an optimization operation framework for VPP participating in multiple types of electricity markets is proposed.Secondly,integrating the uncertainty set of renewable energy output based on the Wasserstein distance and the typical scenario set of electricity market prices based on scenario analysis,a two-stage DRO model for VPP day-ahead bidding and intra-day dispatch considering FRP is constructed.Finally,the effectiveness of the proposed model is validated by taking a VPP as a case.The results of the case demonstrate that the proposed VPP operation strategy has good dispatching economic efficiency and risk robustness,and can maximize the operation revenue in multiple types of electricity market transactions.
