    摘要:

    合理的分布式储能配置在园区能源消纳过程中扮演着至关重要的角色。在进行储能电池配置时如何考虑多个园区之间的联络关系以及配置经济性和能源消纳效益之间的制约关系是一个难以解决的问题。此外,现代配电网多为闭环设计开环运行,多园区间的动态联络也是促进能源消纳的重要技术手段。因此,提出一种考虑网络重构的多园区储能的多目标优化配置模型及方法。首先,该模型将配置经济性和可再生能源消纳效益之间的制约关系进行了数学表征,考虑各种投资及运行约束,并引入虚拟功率表征各个园区之间的联络状态,通过网络的动态重构,从系统层面上提高能源消纳水平;其次基于二阶锥松弛及多面体线性化方法将原始难以直接求解的混合整数非线性非凸模型转化为混合整数线性规划模型;最后将所提算法应用于改进的IEEE 33节点系统中,构建多目标帕累托曲线。结果表明,多园区间的动态联络有助于提升彼此能源消纳水平,所提方法能够为工程实践提供多目标储能配置最优解。

    Abstract:

    Reasonable distributed energy storage configuration plays a crucial role in the energy consumption process of the park. How to consider the connection between multiple parks and the constraints between economic costs and energy consumption benefits is a difficult problem to solve when configuring energy storage batteries. In addition, modern distribution networks are mostly closed?loop and open?loop operation, and the dynamic connection between multiple parks is also an important technical means to promote energy consumption. This paper proposes a multi?park energy storage multi?objective optimal configuration model considering network reconfiguration. First of all, the model mathematically represents the constraint relationship between configuration economy and energy consumption benefit, considers various investment and operation constraints, and introduces virtual power to represent the connection state between various parks; The model improves the energy consumption level from the system level through the dynamic reconstruction of the network. Secondly, based on the second?order cone relaxation and polyhedral linearization method, the original mixed?integer nonlinear non?convex model, which is difficult to solve directly, is transformed into a mixed?integer linear programming model. Finally, the proposed method is applied to the improved IEEE 33 bus system to construct a multi?objective Pareto curve. The results show that the dynamic connection between multiple parks is helpful to improve each other's energy consumption level, and the proposed method can provide the optimal solution of multi?objective energy storage configuration for engineering practice.
