基于信息间隙决策理论的综合负荷聚合商储能优化配置模型
摘要：储能配置是综合负荷聚合商(integrated load aggregator，ILA)参与综合能源系统，保证自身发展的重要手段之一。然而，在与ILA相关的研究结果中，鲜有关于ILA侧最优储能配置的报道。为此在建立电−气联合市场机制的基础上，引入信息间隙决策理论(information gap decision theory，IGDT)方法，对此进行研究。首先，构建电−气联合市场机制，以ILA年费用最小化为目标，建立市场机制下ILA储能优化配置模型。其次，针对电−气市场中的实时电价和气价的不确定性，引入IGDT，得到2种不同风险态度的ILA储能优化配置模型。最后，通过算例分析，得到不同风险态度下ILA的储能容量配置及对应的购售电/气策略；并分析不同日前电价和气价对储能配置的影响，以及不同储能配置方案对ILA经济性的影响。
Abstract:The energy storage configuration is one of crucial means for integrated load aggregator (ILA) to participate integrated energy system (IES) and to ensure the development of its self-development. However, in existing reports about ILA research the research related to the optimal energy storage configuration at ILA side have been seldom reported. For this reason, on the basis of establishing joint market mechanism of electricity-gas the IGDT method was led in to research this topic. Firstly, a joint market mechanism of electricity and gas was constructed, in which the minimum annual cost of ILA was taken as the objective to establish the optimal model of energy storage configuration for ILA under market mechanism. Secondly, in allusion to the uncertainty of real-time electricity price and gas price in electricity-gas market, the information gap decision theory (IGDT) was led in to obtain two optimized energy storage configuration models of ILA with two different risk attitudes. Finally, by means of analyzing calculating example, the capacities of energy storage configurations of ILA under different risk attributes as well as corresponding purchasing and selling strategies of electricity and gas were obtained, and the influences of different day-ahead electricity price and gas price on energy storage configuration as well as the influences of different energy storage configuration schemes on the economy of ILA were analyzed, and the influences of different energy storage configuration schemes on the economy of ILA were analyzed.
