【摘要】：针对微网中源储荷的协同配置问题,为确保微网系统的经济性,在规划阶段需细致考虑源储荷的配比问题。提出了基于雨流计数法的电池健康状态评估方法,考虑储能电池健康状态(state of health,So H),以源储荷净收益最大为目标,提出了电池储能系统各时段充放电功率的优化方法,综合考虑了运行效益、补贴及上网收益、延缓配电网升级带来的效益、碳减排效益、投资运维及电池替换成本,以投资回报率为指标,建立了源储荷的协同配置模型,并提出了一种双层多目标优化求解方法,通过实际算例仿真分析,结果表明:所提出的源储荷协同配置方法能够实现微网系统的经济性,该文算例中,光储荷的适宜配比为0.7:0.125:1,储能系统持续放电时间为3 h,源储荷的协同配置受电价、负荷、收益构成、光储成本、储能技术特性等多因素制约。仿真结果证明了模型及其求解方法的有效性,可为微网中源储荷的协同配置提供参考。
[Abstract]:In order to ensure the economy of the source storage in the micro network, in order to ensure the economy of the microgrid system, the proportion of the source and storage in the planning stage should be carefully considered. A method of evaluating the health state of the battery based on the rain flow counting method is put forward, considering the health state of the energy storage battery (state of health, So H), and the goal of the maximum net return of the source is proposed. The optimization method of charging and discharging power in each period of the battery energy storage system has taken into account the efficiency of operation, the benefit of subsidies and Internet access, the benefit of postponing the upgrading of the distribution network, the benefit of carbon emission reduction, the cost of investment and maintenance and the replacement cost of the battery. The cooperative configuration model of the source storage charge is set up with the return on investment as the index, and a double layer multi-objective optimization is put forward. The result shows that the proposed method can realize the economy of the microgrid system. In this example, the appropriate proportion of the storage load is 0.7:0.125:1, the continuous discharge time of the energy storage system is 3 h, the cooperative configuration of the source storage system is subject to the electricity price, the load, the income composition, the storage cost, and the storage cost. The simulation results prove the validity of the model and its solution method, and provide a reference for the collaborative allocation of source and storage in microgrid.
