Energy management between power generation, storage, and consumption for building microgrid

In recent years, the use of renewable energy has been increasing and energy storage equipment is standard equipment for renewable energy. Under the strong development of green energy by the government, it has also driven the application of a large number of energy storage equipment. It uses batteries as energy storage. In the island strategy, only the internal energy storage and green energy are used. To perform the energy management for the building microgrid, the energy scheduling algorithm designed in this paper is based on the remaining battery power and solar power as the benchmark, because all commercially available energy storage equipment has been abandoned. The method is used to reduce the state of virtual charging. The main reason is that the load control requires additional hardware and control methods. Therefore, when using the abandoned method, insufficient power consumption is present at night. This has led to a reduction in battery life, and this aspect has been taken as the research direction for this purpose. It is planned to apply the optimization algorithm for controlling the load, so that the power generation and battery power can be effectively used. Besides, the loads can be graded to perform the demand management when power is interrupted.
