The two types of classification of photovoltaic power generation
A photovoltaic power station refers to a power generation system that utilizes solar energy and consists of special materials such as silicon panels, inverters, and other electronic components. It is connected to the grid and supplies power to the grid.
Photovoltaic power stations have advantages in promoting the development of the "dual carbon" goals, accelerating the transformation of the power system, optimizing the energy structure, enhancing grid regulation capabilities, and fostering technological innovation.
Photovoltaic power generation generally includes centralized photovoltaic and distributed photovoltaic:
Centralized Photovoltaic: Large-scale photovoltaic power stations built in open areas rich in solar resources. Direct current is converted into alternating current through grid-connected inverters and transmitted to the high-voltage transmission system to supply long-distance loads. It is characterized by large investment scale, long construction periods, and large land areas.
Distributed Photovoltaic: Power systems located near the user's site, typically consisting of photovoltaic modules, combiner boxes, inverters, etc. These are mainly built on the roofs of factories, office buildings, and residential homes. The electricity generated is consumed in a "self-consumption and surplus power fed to the grid" or "full-grid connection" manner. It has the advantages of small land area, low dependence on grid power, and flexibility.
