摘　　要：光伏微网储能系统(PMESS)用电峰谷差的增大会导致电网负荷波动增大,影响电网的稳定性。为了有效降低电网的峰谷差,提出一种光伏微网储能系统用电峰谷差自适应控制技术。通过估计光伏微网发电系统的负荷,计算光伏微网储能系统的充电功率和电量,并根据该计算结果计算光伏微网储能系统的额定容量。设置用电峰谷差自适应控制约束条件,并结合二轮迭代的方式实现光伏微网储能系统用电峰谷差自适应控制。实验结果表明,所提技术可以准确估计光伏微网发电系统负荷,并将用电峰谷差控制在200 kW左右,同时,可以有效提升光伏微网储能系统的有功功率,具有良好的实际应用效果。The increase in peak valley difference in electricity consumption of photovoltaic microgrid energy storage system(PMESS)can lead to increased load fluctuations in the power grid,affecting the stability of the power grid.In order to effectively reduce the peak valley difference of the power grid,a PMESS adaptive control technology for the peak valley difference in electricity consumption is proposed.By estimating the load of photovoltaic microgrid power generation system,the charging power and quantity of PMESS is calculated,and the rated capacity of PMESS based on the calculation results is calculated.The constraints for adaptive control of peak valley difference in electricity consumption are set,and combining with a two round iteration method,the PMESS adaptive control for peak valley difference in electricity consumption is implemented by means of two rounds of iteration.The experimental results show that the proposed technology can accurately estimate the load PMESS and control the peak valley difference in electricity consumption to around 200 kW,which can effectively improve the active power of PMESS and has good practical application effects.
