Description

Technical Field

[0002] Source-grid-load-storage is an operating model that includes an overall solution for power supply, power grid, load and energy storage. It can accurately control society, interruptible electricity load and energy storage resources, improve the safe operation level of the power grid, and solve problems such as grid volatility in the process of clean energy consumption. Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels, controllers and inverters. The main components are composed of electronic components. After the solar cells are connected in series and packaged for protection, they can form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

[0003] The construction of photovoltaic power generation and energy storage device with integrated source, grid, load and storage is one of the important new energy development infrastructures of the country.
