Energy management method of building microgrid considering energy consumption characteristics and virtual energy storage

The proportion of building energy consumption in the total social energy consumption is increasing year by year, and the refined energy management method integrating building attributes and energy consumption characteristics has become the key to the economic and efficient operation of building microgrid. This paper proposes an energy management method of building microgrid considering energy consumption characteristics and virtual energy storage. Firstly, the system model is established for users and buildings, incorporating virtual energy storage with conventional energy storage system, electric vehicles and building virtual energy storage. Secondly, the building energy consumption model is established considering the human behavior characteristics and architectural attributes of buildings. Thirdly, the energy management model based on the Stackelberg game is then formulated, where users minimize costs and building operators maximize profits by adjusting energy prices based on user responses, and a distributed algorithm iteratively solves this to reach equilibrium. Finally, the numeri cal example validates the model and algorithm, analyzing the effects of human behavior on virtual energy storage and comparing generalized storage systems and strategies.
