Optimal Configuration Method of Distribution Network Sensing Control Terminal Considering Source-Load-Storage Coordination

With the continuous development of the new distribution network, the degree of distribution automation is bound to be higher and higher. The distribution network perception control terminal can realize the observability, measurability and controllability of the distribution network, and improve the dynamic perception ability of the distribution network. In order to ensure the safety, stability and economic operation of the new distribution network, it is urgent to study the optimal configuration method of the sensing control terminal of the distribution network. Aiming at the current situation of large-scale access of distributed new energy in new distribution network, an optimal configuration method of sensing control terminal based on source-load-storage collaboration is proposed. Firstly, based on the output model of distributed generation (DG), flexible load and energy storage, the optimal configuration model of the terminal is established with the goal of minimizing the comprehensive operation cost and the constraints of different business communication requirements. Secondly, based on the improved particle swarm optimization algorithm, the optimal configuration results of the distribution terminal are obtained. Finally, the effectiveness and superiority of the proposed method are verified by the simulation analysis of IEEE 33-bus distribution system using MATLAB and OPNET software.
