Microgrid photovoltaic power generation model
This study presents a machine learning-based photovoltaic (PV) model for energy management and planning in a microgrid with a battery system. A microgrid is a group of interconnected loads and distributed energy resources that acts as a single controllable entity with respect to the grid. It can connect and disconnect from the grid to. . These factors motivate the need for integrated models and tools for microgrid planning, design, and operations at higher and higher levels of complexity. This model can be applied to improve the consumptive ability of new energy resources, optimize the power combination, and realize the sustainable development of the power system. 8 March 2021; 2333 (1): 090020.
