Research on optimization operation mode of park integrated energy system for demand response
In order to show the characteristics of coordination and cooperation of various energy networks better in the park integrated energy system,and effectively improve the economy of the system operation,an optimal operation model of the park integrated energy system based on combined heating and cooling power supply is proposed,which considers the comprehensive demand response under four kinds of network load constraints.Firstly,four kinds of energy networks of electric heating and cooling are established in a park,and mathematical models of various energy conversion equipment and energy storage devices inside the system are established.Meanwhile,the thermal inertia of heating or cooling system is considered.On this basis,the optimal scheduling model is carried out with the optimal economy of the system,and the Gurobi solver in MATLAB platform is used to solve the proposed model.Through the analysis of examples,it can be concluded that the comprehensive demand response mode can plays the role of"peaking and valley filling"on the load,and can alleviate the energy supply pressure better than the mode without considering the comprehensive demand response during the peak period of the system,and can more effectively reduce the daily operating cost of the integrated energy system in the park,the total operating cost of the system is reduced by 5.7％,so that the economy of the system operation is improved.
