Since the existing capacity load ratio calculation methods do not take into account the impact of different voltage levels on AC grid,they cannot ensure the optimization of the reliability and economy of AC grid at the same time.To solve this problem,a capacity load ratio calculation method for AC grid at multiple voltage levels is proposed on the basis of considering voltage levels.The power supply capacities of AC grid in high-and low-voltage modes are calculated,respectively.According to the power supply capacity,the discrete particle swarm optimization algorithm is used to calculate the particle number of capacity load ratio at different voltage levels,and the optimal capacity load ratio calculation results of AC grid at multiple voltage levels are obtained,so as to realize the capacity configuration optimization of AC grid at multiple voltage levels.Experimental results show that the proposed method can optimize the transformer's capacity load ratio,and the power supply reliability,economy and satisfaction score of AC grid are higher.
