Abstract

Abstract: Combined cooling, heating and power system (CCHP) can realize the cascade utilization of energy and improve the energy utilization efficiency. Focusing on the phenomenon that the traditional self-sufficiency mode is easy to cause insufficient or excess regional energy supply, considreing the complementarity between different regional load characteristics, an internal multi-region interconnected complementary energy supply method based on aggregator mode was proposed. In order to solve the problem of uncertainty in the optimal dispatching of multiple resources in the region under the aggregator mode, an optimal dispatching model based on interval linear programming was constructed, which took the minimum operation cost of aggregator as the objective function. The feasibility and effectiveness of the method are verified by analyzing the aggregator mode in residential area, commercial area, office area and industrial area. The results show that the operation cost can be reduced and the economic benefit can be improved under the aggregator mode.
