In order to improve the operation safety and power supply quality of medium and low voltage distribution network,the power planning method of medium and low voltage distribution network based on multi-objective optimization is studied.The two-layer power planning model and adaptiveε-dominated multi-objective particle swarm optimization(PSO)are used to solve the two-layer power planning objectives of medium and low voltage distribution networks.The test results show that this method can reduce the construction cost and voltage deviation of the distribution network,and ensure the stable operation of the distribution network.
