Operation optimization and analysis of office building integrated energy system considering comprehensive demand response of heat and electricity

Abstract

With the problem of energy shortage and environmental degradation becoming more and more serious, the integrated energy system (IES) based on the distributed energy supply of clean energy and multiple heterogeneous energy supply has become an important method to solve this problem. In this paper, the office building is taken as the object, and proposes the operation optimization strategy of IES considering energy storage coordination to participate in comprehensive demand response (CDR) of heat and electricity. Firstly, the IES is constructed to improve the energy supply flexibility. Secondly, taking the CDR as the breakthrough point, the energy storage collaborative optimization is further used to fully tap the potential of the demand side management. Finally, with maximizing the demand response (DR) rate and minimizing the daily energy consumption cost as the objective function, the operation optimization mathematical model of IES considering CDR is established. By analyzing the simulation results of different schemes, it is further verified the strategy proposed in this paper makes IES complete DR task, reduces the energy consumption cost of 1120 yuan, and improves the energy-using comfort.
