考虑微电网群和系统经济运行的配电网储能优化配置
摘要：针对不同的配电网运行情况，考虑微电网群的运行策略以及子微网的协作运行对配电网的影响，建立了配电网储能配置的选址和定容两阶段优化模型。其中，第一阶段的选址模型在日运行时间尺度上，以配电网系统运行成本最小为目标，利用GAMS软件求解储能的位置、个数以及充放电策略；第二阶段的容量优化模型以年作为时间尺度，以配电网中储能投资运行维护年成本最小为目标，利用嵌套储能寿命计算的粒子群算法在MATLAB软件中求解。算例证明在不同的运行场景下，考虑微电网群和系统经济运行的配电网储能优化配置方法可以有效减少配电网的运行成本和储能的投资维护成本，提高系统经济性。
Abstract:In allusion to different operation conditions of distribution network, considering operation strategies of microgrid clusters and the influence of collaborative operation of sub-microgrids on distribution network, a two-stage optimization model for site selection of energy storage allocation and their capacity determining for distribution network was proposed. In the first-stage, the lowest operating cost of the distribution system was taken as the objective on the time scale of daily operation, and the position and the number of the energy storage equipment as well as the charge-discharge strategies were solved by GAMS software; for the capacity optimization model in second-stage, the lowest yearly operating cost consisted of the investment, operation and maintenance of the energy storage equipment in distribution network was taken as the objective on the time scale of one year, and the particle swarm optimization algorithm, in which the nested energy storage life calculation was utilized, was used to be solved in MATLAB software. Results of calculating example show that under different operational scenarios, the optimal configuration method of energy storage equipments in distribution network, in which the economic operation of microgrid clusters and distribution system are taken into account, can effectively reduce the operational cost of distribution network and the investment and maintenance cost of energy storage, thus the economy of distribution network can be improved.
