Capacity allocation strategy of integrated energy system considering seasonal factors and flexible load

First of all, taking the northern industrial and commercial park as the research object, the comprehensive energy system architecture and mathematical model of the park are established. Considering the constraints of energy supply network and aiming at the lowest total cost in the whole life cycle, a coupling model of electric hot gas multi-energy flow is established, and the capacity allocation is carried out in the period of season. According to the user's electricity consumption behavior, the flexible electric heating load is included in the optimal configuration of four seasons, and the mixed integer linear programming is applied to solve the problem. The example shows that the capacity demand of gas turbine and gas boiler is the largest in spring, and the power demand of the park can only be satisfied according to this configuration. Flexible load participation planning can promote coordinated operation of equipment, reduce configuration cost, improve economy, smooth load curve and system stability.
