摘要
为解决光伏在并网过程中功率波动的问题,首先根据国标设置功率波动的死区限值,然后对光伏控制系统进行理论分析,并且选取测试过程中功率波动较大的光伏数据,采用自适应指数移动平均算法对其优化,最后在MATLAB中搭建仿真模型,验证光伏和储能系统能够将超出死区的功率控制在一定范围内,同时维持系统电压的稳定。
In order to solve the problem of power fluctuation in the process of photovoltaic grid connection,firstly,the dead band limit of power fluctuation is set according to the national standard.Then,the photovoltaic control system is analyzed theoretically,and the photovoltaic data with large power fluctuations during the test process are selected,and the adaptive exponential moving average algorithm is used to optimize it.Finally,a simulation model is built in MATLAB to verify that the photovoltaic and energy storage systems can control the power beyond the dead zone within a certain range while maintaining the stability of the system voltage.
