摘要

随着“碳达峰·碳中和”目标的提出，可再生能源大规模并网对电力系统灵活运行提出了更高要求。虚拟电厂（VPP）通过聚合分布式资源，将灵活爬坡产品（FRP)纳入运营策略，参与多类型电力市场以提升运营收益。基于此，提出了考虑FRP的VPP两阶段分布鲁棒优化（DRO）运营策略。首先，考虑高比例可再生能源渗透率下的FRP市场，结合多类型分布式资源运行特性，提出VPP参与多类型电力市场的优化运营框架；其次，结合基于Wasserstein距离的可再生能源出力不确定集和基于场景分析法的电力市场价格典型场景集，构建考虑FRP的VPP日前投标和日内调度两阶段DRO模型；最后，以某VPP为例对所提模型进行有效性验证。算例结果表明，所提VPP运营策略具有较好的调度经济性与风险鲁棒性，在参与多类型电力市场交易中能够实现运营收益最大化。

Abstract

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.
