摘　　要：在开放电力市场中引入价格型需求侧响应能够使市场竞争更有效,电价更合理,但分时电价无法体现实际市场供需,且实时电价波动性大,实施难度大。为了将需求侧响应和电力市场有机结合,结合我国电力市场发展提出了浮动高峰电价产品并分析了其特点和效益。在此基础上,基于用户电价响应模型,建立了考虑用户满意度的购售双方运营优化模型,并设计了3种场景进行算例分析。结果表明,浮动高峰电价产品能增加平衡账户总收益,在保障用户用电成本不变的前提下,增加售电公司和用户的收益,降低负荷峰谷差。In the open electricity market,the introduction of a price-based demand response can make market competition more efficient and electricity prices more reasonable.However,the time-of-use price can not reflect the actual market supply and demand.The real-time price is highly volatile and difficult to implement.In order to combine the demand-side response with the electricity market,this paper proposes the variable peak price products and analyzes its characteristics and benefits in combination with the development of electricity market of China.On this basis,based on the user's electricity price response model,the operational optimization model of both purchase and sale considering customer satisfaction is established,and three scenarios are designed for case analysis.The results show that the variable peak price product can increase the total revenue of balance account,increase the profit of the retailer and users,and reduce the load peak-to-valley difference under the premise of ensuring the cost of the user's electricity unchanged.
