Active Distribution Network Optimization Based on Improved Tunicate Swarm Algorithm

As distributed power sources and power electronic equipment are continuously connected to the distribution network, the power electronics on the distribution network side are increasingly deepened. At the same time, unreasonable access to a large number of distributed power sources can negatively affect the radial distribution network. In this paper, we consider drop control to realize power distribution for the impact brought by power electronics on the distribution network, and on this basis, we consider the improved Tunicate Swarm algorithm(ISC-TSA) to conduct simulation experiments in IEEE-69 system to realize the optimal allocation of distributed power sources and compare the scenarios with and without considering the impact brought by power electronics respectively. The experimental results show that using drop control as a power allocation strategy will have an impact on power quality and active losses.
