Energy Management for Building Integrated Energy System Considering Generalized Energy Storage

Energy storage equipment can improve the utilization rate of clean energy and reduce the operation cost of the building system. But the development of traditional energy storage is limited because of its high cost. In order to give full play to the advantages of energy storage in the building integrated energy system (BIES), the demand response, electric energy storage and thermal energy storage are integrated into the generalized energy storage (GES) resources for unified coordination. On the basis of fully considering the operation constraints of various equipment, the BIES operation model with the goal of minimizing the operation cost of BIES is constructed. In addition, due to the strong uncertainty of clean energy, the k-means method is used to generate the scenarios of photovoltaic and wind power. And then the conditional value at risk (CVaR) method is used to quantify the risk caused by uncertainties. Finally, the CPLEX solver is used to verify the effectiveness of the proposed model in Matlab environment.
