Joint optimization method of distribution network grid planning and multi-module intelligent terminal configuration

Aiming at the problems that the existing grid planning method of distribution network fails to fully coordinate with the secondary equipment and the incomplete consideration of the types of secondary equipment, a joint optimization method of grid planning and multi-module intelligent terminal configuration is proposed. The component module of the multi-module intelligent terminal is introduced and the fault handling strategy for protection and automation is analyzed. Based on the fault handling strategy, the fault handling time and feeder zoning logic of the distribution network with the multi-module intelligent terminal is defined. Then, the collaborative planning framework of distribution network grid planning and multi-module intelligent terminal configuration is proposed. Besides, the alternate optimization mathematical model is constructed, and the particle swarm optimization algorithm is adopted to solve the model. The effectiveness and practicability of the proposed method is verified through two examples of IEEE RBTS BUS-2 distribution system and a 60-bus urban distribution network.
