分布式光伏集群反向潮流过载抑制动态控制方法
Dynamic control method for reverse power flow overload suppression in distributed photovoltaic clusters
摘要
Abstract
Construct an optimization control algorithm aimed at maximizing the consumption of photovoltaic power,accurately calculate the minimum reduction amount,and introduce a dynamic threshold adjustment mechanism.This mechanism can flexibly adjust the dynamic reverse power flow threshold according to the acceptance capacity and stability requirements of the main grid to adapt to the grid demands under different working conditions.The results show that the proposed intelligent control method can effectively suppress reverse power flow overload,reduce the transformer load rate from a maximum of 78%to within 75%,and strictly control the reverse power flow within the dynamic reverse power flow threshold.The proportion of photovoltaic reduction by this method is only about 4.9%.While effectively alleviating reverse power flow,it retains the maximum amount of power generation,achieving the goal of effectively suppressing reverse power flow overload on the basis of ensuring the safe operation of the power grid.关键词
