Abstract

Abstract:

With the rapid development of energy networks， integrated energy systems significantly improve general utilization rate of energy by making comprehensive use of various energy sources， such as heat，cold energy and electricity. Thus，the system has become the research focus. In view of the capacity allocation and scheduling strategy for regional integrated energy systems， an optimization method is proposed. Based on the structure of the system and the mechanisms of energy conversion， a mixed integer linear programming model is constructed， whose optimal solution for the allocation and scheduling strategy can be obtained simultaneously by the solver.The simulation results show that the proposed method can achieve the economic， flexible and efficient operation of regional integrated energy systems， reduce the operation cost and balance the energy supply and demand.

Key words: integrated energy system, capacity configuration, scheduling strategy, mixed integer linear programming, sensitivity analysis
