摘要:

随着居民用能量的不断升高,综合需求响应已经成为保障上级能源网安全稳定、提高能源转换效率和挖掘需求侧潜力的重要手段。针对考虑综合需求响应的综合能源系统中各方参与者最优决策问题,文章基于势博弈理论建立了以各方收益最大为目标的运行优化模型。模型在考虑电、热、冷多能互补的前提下,引入综合能源系统运营商并和用户、上级能源网进行交互。构建了模型对应的势函数,将求解模型的纳什均衡转化为求解势函数最优值,并采用分布式优化算法求解。仿真模拟结果表明,所建模型可以较快求得纳什均衡解,在用户利益不受损的前提下增加了运营商的收益,削减了峰谷差,提高了电网稳定性。

Abstract:

With the continuous increase of energy used by residents, integrated demand response (IDR) has become an important means to improve the safety and stability of the superior energy network and to improve the energy conversion efficiency and exploit the potential of the demand side. In order to solve the problem of optimal decision of all participants in an integrated energy system (IES) considering the IDR, this paper builds an operation optimization model based on the potential game theory with the objective function of maximizing revenue. In this model, multi-energy supplement is considered and the IES operator is introduced. The operator interacts with both the user and the superior energy network. The potential function corresponding to the model is constructed, and the problem of finding the optimal solution of the model is transformed into the problem of finding the maximum value of the potential function. In this paper, distributed optimization algorithm is used to solve the model. The simulation results show that the Nash equilibrium solution can be obtained quickly. The operator's income can be also increased, the peak-valley difference can be reduced, and the stability of the power grid can be also improved without reducing the user's benefit.

Key words: integrated demand response (IDR), multi-energy supplement, integrated energy system (IES), potential game, distributed optimization
