In the existing typical architectural design

solar photovoltaic power generation

energy storage system

DC power distribution

and flexible control have been introduced to form a photovoltaic-energy storage-DC-flexible microgrid system. It connects distributed photovoltaic

energy storage

and loads through a "DC bus"

enhancing the flexibility of load power consumption and improving the utilization rate of solar energy. This article takes the design project of a photovoltaic-energy storage-DC-flexibility microgrid system for a high school as an example

providing a detailed explanation of the design structure and application of the photovoltaic microgrid system.
