Multi-Objective Optimal Control for Distribution Network Loop-Closing Operation Using PE-MOPSO Algorithm
2021
The loop-closing operation is usually used to transfer power supply without power interruption in the distribution network, but the excessive current induced by loop-closing will endanger the safety and stability of the distribution network. This paper presents a multi-objective optimal control method of loop-closing in distribution network. Firstly, the mathematical optimization model of loop-closing optimal regulation is established, which not only ensures the security of loop-closing operation, but also takes into account the stability and voltage quality of distribution network operation. Then, Pareto entropy-based multi-objective particle swarm optimization (PE-MOPSO) algorithm is proposed to solve the optimization problem. Finally, an actual example is simulated based on MATLAB platform. The simulation results show that the optimization model is correct, and PE-MOPSO algorithm has good diversity and convergence, and can give a reasonable control scheme.
