摘要: 需求响应聚合商通过需求响应聚合用户的可转移负荷和可削减负荷,提高区域综合能源系统运行的灵活性和经济性。考虑综合能源系统运营商和需求响应聚合商之间的交互博弈关系,建立了计及需求响应的区域综合能源系统双层优化调度模型。上下层分别以区域综合能源系统运营商和需求响应聚合商经济收益最大为目标,利用KKT条件和线性化方法将双层模型转化为单层混合整数线性优化模型进行求解。结果显示,通过分时电价和需求响应补偿价格引导用户调整用能计划,可在提高综合能源系统运营商和需求响应聚合商的利润的同时实现削峰填谷,减少对电网安全稳定运行造成的影响。

Abstract: Demand response aggregator aggregates users’ transferable loads and reducible loads through demand response to improve the flexibility and economy of regional integrated energy system. Considering the interactive game relationship between the integrated energy system operators and the demand response aggregators, a two-level optimal dispatching model of the regional integrated energy system is established with consideration of the demand response. By taking the maximum economic benefits of the regional integrated energy system operators and the demand response aggregators as objective respectively for the upper and lower layers, the KKT conditions and linearization method are used to convert the two-layer model into a single-layer mixed integer linear optimization model for solution. The results show that using the time-of-use electricity price and the demand response compensation price to guide users to adjust their energy use plans can increase the profits of integrated energy system operators and demand response aggregators while achieving peak load shaving and reducing the impact on the safe and stable operation of the power grid.
