摘要
风电光伏等可再生能源大规模并网,增大了电网调峰压力,需要发掘需求侧资源参与调峰。从交易组织、交易流程、交易结算3个方面设计了考虑虚拟电厂参与的调峰辅助服务市场机制,使虚拟电厂与火电机组同台平等参与深度调峰市场竞价,并分别给出了深度调峰市场日前出清和实时出清模型。交易采用按报价出清的方式,火电机组和虚拟电厂根据实际调用的调峰容量和申报价格获得收益。最后通过算例分析验证了所提市场机制和模型的有效性。
Renewable energy sources such as wind power and photovoltaics connected to the grid on a large scale have increased the peak regulation pressure of the power grid.Therefore,the power grid needs to consider the use of demandside resources for peak regulation.This study designs a peak regulation ancillary service market mechanism considering the participation of virtual power plants(VPPs)from three aspects:transaction organization,transaction process,and transaction settlement.Further,it proposes that thermal power units and VPPs equally participate in the bidding of the deep peak regulation market.A day-ahead clearing model and a real-time clearing model of the peak regulation market are presented.They adopt paying as the bid mode.The thermal power unit and VPPs can gain profits according to the actual peak regulation capacity and the bid prices.Finally,a case analysis and numerical results show the effectiveness of the proposed market mechanism and the clearing model.
