Research on Energy Management Scheme of Commercial Buildings Cluster Considering Demand Response

Aiming at the problems of high energy consumption cost and insufficient demand response potential of commercial buildings cluster, a comprehensive energy management system for commercial buildings cluster considering distributed generation, energy storage equipment and electrical load is constructed. The optimization model is established with the lowest electricity cost of building operation as the objective function. Meanwhile, through the evaluation and assumption of the demand response potential of various loads in commercial buildings, the demand-price elasticity model under the real-time electricity price mechanism is introduced, and the double-layer optimization algorithm is adopted to optimize the solution of the given model. Through the simulation of the example, the power operating costs of the commercial buildings cluster under three different cases of distributed power generation outputs, as well as whether to participate in demand response are compared. The results show that the energy management scheme and demand response strategy given by the double-layer optimization algorithm can effectively reduce the electricity costs of the commercial buildings cluster and achieve economic operation.
