Abstract:

In order to solve the problems of low power transmission efficiency in AC distribution network, a comprehensive energy system configuration method is proposed based on AC/DC hybrid distribution network that integrates medium voltage and low voltage levels, which can improve the new energy consumption capacity and power supply reliability. Firstly, a two-level programming model of integrated energy service equipment configuration and daily operation economy is established. Then, the improved moth flame optimization algorithm is combined with CPLEX to solve the problem. Finally, the optimal integrated energy equipment configuration scheme is obtained under the given example, and the various costs under the traditional AC distribution network are compared and analyzed, which proves that the integrated energy system based on the AC/DC distribution network is more advanced and reliable.

Key words: integrated energy systems, AC/DC distribution network, double planning, improved moth flame optimization(IMFO) algorithm
