The invention discloses an electric vehicle demand response ratio optimization method and system considering dual uncertainty. A dual-layer ratio optimization model comprehensively considering source load uncertainty and response uncertainty is constructed. The upper layer takes a power grid operator as a main body, in order to consider the uncertainty of the source load, a random optimization method is adopted to construct a demand response ratio optimization model, the IBDR ratio, the energy electricity price and the excitation electricity price are optimized and transmitted to the lower layer EVA, and the IBDR ratio is defined as the ratio of the EVA load participating in the IBDR to all the EVA loads. And the lower layer takes EVA as a main body, puts forward a DRIN (Demand Response Inference Network) based on data driving, reasones an EVA response strategy aiming at the PBDR and the IBDR, outputs a mean value and a variance of the EVA response strategy, represents the EVA demand response strategy considering the response uncertainty by using the mean value, and returns the EVA demand response strategy to an upper layer power grid operator. And repeatedly iterating the upper layer and the lower layer until the maximum number of iterations is reached or the total cost change of the power grid operator is less than a threshold value, and finally outputting the IBDR ratio and the total cost of the power grid operator.
本发明公开了考虑双重不确定性电动汽车需求响应配比优化方法及系统,构建综合考虑源荷不确定性与响应不确定性的双层配比优化模型。上层以电网运营商为主体,为考虑源荷不确定性,采用随机优化方法构建需求响应配比优化模型,优化IBDR配比与能量电价、激励电价并传递给下层EVA,其中IBDR配比定义为参与IBDR的EVA负荷占全部EVA负荷的比例。下层以EVA为主体,提出基于数据驱动的需求响应推理网络(Demand Response Inference Network,DRIN),针对PBDR和IBDR,推理EVA响应策略,输出EVA响应策略的均值与方差,并用均值代表考虑响应不确定性的EVA需求响应策略,返回给上层电网运营商。上下层反复迭代,直至达到最大迭代次数或者电网运营商总成本变化小于阈值后,最终输出IBDR配比及电网运营商总成本。
