Abstract
In order to promote building energy conservation and realize the coordinated control and management of distributed energy in different buildings, this paper firstly builds a building virtual power plant framework including wind power, photovoltaics, energy storage equipment, electric vehicles and flexible loads, and expounds the flow of energy and information in the virtual power plant. Then, taking the lowest net cost as the objective function, a coordinated and optimized scheduling model of building virtual power plant is constructed, which also considers the optimal sharing of electric energy between different buildings. Finally, taking a building virtual power plant including a residential building, a commercial building and an office building as an example, three scenarios, i.e., not constructing a virtual power plant, building virtual power plant scheduling each unit in the building and building virtual power plant scheduling units in a building and power sharing between buildings, are analyzed. The scheduling results in the three scenarios are compared to verify the effectiveness of the above models. The results show that the model can realize the coordinated optimization of electric energy within the building and among different buildings, and effectively improve the economy and load of the virtual power plant.
