摘要
虚拟电厂作为一种具备储能特性的灵活性资源,虽然其在配合电网削峰填谷、消纳新能源等方面的作用越发重要,但其目前在市场运营上缺乏经济性及高效性,直接导致其参与市场积极性不足.鉴于此,提出一种虚拟电厂参与电能量市场与辅助服务市场协同工作策略.首先,基于现货市场电价与虚拟电厂的聚合情况,确定其参与市场各时段策略;其次,以虚拟电厂收益最大化为目标,采用动态规划方法构建多时间尺度下虚拟电厂参与现货电能量-调频市场协同优化模型;最后,通过仿真分析对比虚拟电厂只参与单独市场与联合优化情况下的收益及利用率,并使用shapely值法对参与虚拟电厂聚合的各类资源进行收益分摊分析,验证所提方案的可行性及有效性.
Abstract
As a flexible resource with energy storage characteristics,virtual power plant(VPP)is becoming more and more important in cooperating with the grid for peak load shaving and new energy accommodation.However,its poor economy and efficiency in market operation directly leads to its lack of enthusiasm in participation in the market.In view of this,this paper proposes a collaborative work strategy for VPP participating in electricity energy market and auxiliary services market.Firstly,based on the spot market electricity price and the aggregation of VPP,the strategy for the VPP participating in the market in each time period is determined.Secondly,taking the maximum revenue of VPP as the goal,the dynamic programming method is used to establish a collaborative optimization model of VPP participating in the spot electricity energy-FM market under multi-time scale.Finally,through simulation,we analyzed and compared the revenue and utilization rate of the VPP participating in the separate market and the joint optimization.The shapely value method is used to analyze the revenue sharing of various resources participating in the aggregation of the VPP,so as to validate the feasibility and validity of the scheme proposed in this paper.
