Abstract

Abstract: The difficulty of clean energy accommodation is one of the problems affecting the sustainable development of park integrated energy system (PIES). This paper constructs a comprehensive price demand response model based on the design of time-of-use prices of power and heat and the conversion demand response model including power to gas (P2G)， electric refrigerator (ER) and electric boiler (EB). Firstly， a park integrated energy system， which is composed of an energy supply center and an energy conversion center， and its trading strategy， are constructed. Secondly， on the basis of considering the comprehensive price demand response and the conversion demand response， an optimal scheduling model with the objective function of maximum system net income is constructed with the constraints of the energy balance before and after the demand response. Then， the performance evaluation indicators are constructed from economic and environmental aspects. Finally， an example analysis is carried out to verify that the model has the effect of improving clean energy consumption and system economy.

Key words: park integrated energy system（PIES）, comprehensive price demand response, conversion demand response, combined cooling, heating and power（CCHP）, power to gas（P2G）
