摘要: 基于需求响应的智能电网实时电价机制是调节电力供需平衡的理想手段。用户用电需求行为则对设计高效可行的实时电价定价策略起到调控作用。考虑用户电力总需求的动态变化,以社会福利最大化作为研究目标,改进已有在线实时电价风险模型中的用电风险项,将个体用户的用电量波动调整为全体用户电力总需求的波动,建立优化模型。通过对偶方法等价转换原优化问题,克服原有的在线算法不能求解用户总体用电量的困难,设计一种算法对其求解,得到实时电价。数值仿真结果验证了所建模型的合理性以及算法的有效性和可行性。

Abstract: The real-time electricity price mechanism is an ideal method to adjust the power balance between supply and demand in smart grid. Its implementation has profound impacts on the users' behavior and the operation and management of electricity power grid’s safety. The users’ demand behavior plays a regulatory role in designing real-time electricity pricing strategy. Aiming at maximizing social welfare, the dynamic change of users’ aggregate demand is analyzed, which corrects the electricity risk items in online real-time risk model in the way of changing the individual user’s power fluctuations to all the users’ demand power fluctuations, and the optimization model is rebuilt. An algorithm is presented to overcome the existing online one without computing the overall power consumption by equivalently conversing the optimization problem through dual method. The algorithm will help to get real-time electricity price. The model rationality and the proposed algorithm validity and feasibility are verified by numerical simulation results.

Key words: smart grid, real-time pricing, risk, optimization
