Research on optimal location of energy supply centers of integrated energy system based on K-means++

The integrated energy system can improve the utilization rate of various kinds of energy, solve the problem of energy waste effectively and have good prospects for development. This paper focuses on the location of energy supply centers and region division in integrated energy system. The electric, heat and cold loads at each load point were all considered. According to the characteristics of three kinds of loads, the weight was proposed to distinguish loads, the Manhattan distance which was closer to the actual energy supply route was adopted and the concept of integrated load moment was put forward. The established model takes the minimum of the integrated load moment of the whole region as the objective function and determines the number of partitions based on the constraint condition of the energy supply radius. Combined with the improved K-means++ algorithm, the location of the energy supply centers and the region division were adjusted dynamically. Finally, an example of a northern city was taken to verify the applicability of the method.
