Operation of Residential Integrated Energy System under Integrated Demand Response

Abstract

The integrated energy system is an important carrier to improve energy utilization efficiency and promote the coordination and complementarity of multiple energy sources. In view of the complex multi-energy flow load demand in the residential integrated energy system (RIES) and insufficient consideration of the subsidy mechanism for user participation in demand response, a solution is proposed. The economic dispatch method of intelligent buildings that takes into account the comprehensive demand response. First of all, a building integrated energy system model of combined cooling, heating and power is constructed. Secondly, according to the user's temperature comfort and electricity price demand response, a flexible load demand model including cooling and heating load reduction and electric load transfer is established, and a comprehensive demand response mechanism based on stepped compensation is established. Then, an economic dispatch model with the goal of maximizing system operating profit is constructed, and the CPLEX optimizer is used to solve it. Finally, a simulation example shows that the building integrated energy system optimization strategy that takes into account the comprehensive demand response can coordinate the resources on both sides of supply and demand, and improve the economic benefits of the system and users.
