摘要
为了应对风光大规模并网带来的调峰困难,由此进行计及不确定性与相关性的虚拟电厂参与主辅市场联合交易优化研究。首先,设计虚拟电厂参与主辅市场的交易体系;然后,考虑新能源出力的不确定性以及主电能量市场与调峰辅助服务市场价格的相关性,构建了虚拟电厂参与主辅市场的联合出清优化模型;最后,以某一虚拟电厂为例进行算例分析,算例结果验证了模型的有效性。
Targeting the problem of peak shaving caused by the large-scale grid connection of wind and solar energy,the paper makes a study on the optimization of virtual power plant participating in joint trading in main and auxiliary markets by considering uncertainty and correlation.Firstly,a trading system for the virtual power plant to participate in the main and auxiliary markets is designed.Then considering the uncertainty of renewable energy output and the price correlation between the main power market and the peak shaving auxiliary service market,the joint clearing optimization model of the virtual power plant participating in the main and auxiliary markets is constructed.Finally,the effectiveness of the model is verified with a case of virtual power plant.
