考虑分时电价的微电网储能容量优化配置
摘要:为了合理配置并网型微电网中储能系统容量,提高微电网经济性及其对大电网的削峰填谷能力,提出了一种考虑分时电价的储能容量优化方法。以微电网系统建设成本及运行成本最小化为优化目标,建立了容量优化模型,根据对某地历史源荷数据和配电网分时电价的分析,制定了经济调度策略,通过粒子群优化算法计算得到系统经济性最优的容量配置。在Matlab中建立了仿真模型,分别基于考虑分时电价前后的容量配置进行7日仿真,通过对比2次仿真结果验证了优化方法的有效性。对比结果表明,在容量优化配置中考虑分时电价影响可以有效降低系统运行成本,提高削峰填谷能力。
Abstract：In order to rationally allocate the capacity of energy storage system in grid-connected microgrid, improve the economy of microgrid and its ability of peak load shifting for large grid, an optimization method of energy storage capacity considering TOU(time-of-use) electricity price was proposed. Take minimize the construction cost and operation cost of microgrid system as the optimization target, a capacity optimization model is established, and an economic dispatching strategy is formulated based on the analysis of historical source load data and TOU price of distribution network. Based on this, the optimal capacity allocation is obtained by particle swarm optimization algorithm. A simulation model was established in Matlab, and a 7-day simulation was carried out based on the capacity configuration before and after considering TOU price. The effectiveness of the optimization method was verified by comparing the two simulation results. The comparison results show that considering TOU price can effectively reduce the operating cost of the system and improve the capacity of peak load shifting.
