According to the time-domain spectrum,the demand value of the current photovoltaic power generation capacity in the distribution network was calculated,the demand value was taken as the input,the power fluctuation variance and power average value of the contact line in the distribution network of the distributed photovoltaic power generation capacity were taken as the objective to construct the distributed photovoltaic power generation capacity optimization model,and the adaptive dynamic programming algorithm was used to solve the distributed photovoltaic power generation capacity optimization model to realize the optimization of distributed photovoltaic power generation capacity.The experimental results showed that the maximum deviation of the current distributed photovoltaic generation capacity calculated by the proposed methodwas only 0.003 MW,which can effectively improve the total capacity of distributed photovoltaic power generation in the distribution network.
