Active Power Flow Optimization Method for Multi Terminal Flexible DC Transmission System Based on Improved Sparrow Search Algorithm
In this paper,an active power flow optimization method for multi-terminal flexible DC transmission system based on improved sparrow search algorithm is proposed.With the goal of minimizing power consumption,an optimal active power distribution model is established to reduce network loss.By restraining the active power,the AC line losses in two bus brackets are calculated,and the total losses and rated capacity of the converter system are obtained.Calculate the impact capacity of DC power in the process of transferring to AC line,and get the power transfer in AC channel.At the same time,the improved sparrow search algorithm is used to optimize the active power flow of multi-terminal flexible DC transmission system,calculate and sort the individual fitness,select the optimal individual to update the position,and output the optimal value to distribute the power of the equipment output of AC network.The experimental results show that the node voltage of the multi-terminal flexible DC transmission system power flow optimization method is below 0.92 p.u.,and the network loss is the smallest,which has a good application.
