摘要:Microgrid is a new type of power supply structure and will play an important role in ensuring power supply. Because of the high cost of micro grid construction, this is very necessary to determine the lowest capacity configuration and realize the best function configuration, which is an urgent problem in engineering construction. Therefore, this paper first establishes simulation analysis model, puts forward economic optimization model and constraints, and formulates system configuration scheme and construction cost. The results show that the method is feasible and effective. This scheme not only reduces the operation cost of the system, but also provides a reference for the construction of microgrid engineering.
