What is distributed photovoltaic power generation? Distributed photovoltaic power generation refers to the photovoltaic power generation facilities characterized by the balance adjustment of the power distribution system, which is specially constructed near the user's site. It is a new type of comprehensive utilization of power generation and energy with broad prospects for development. It advocates nearby power generation and nearby Network, the nearest conversion, the nearest use of the principle.
The country has a quantitative definition of distributed photovoltaic power generation, the concept of distributed photovoltaic power generation released by the State Grid as follows:
1. located near the user, the use of electricity generated in situ;
2. Photovoltaic power generation projects connected to the grid at voltage levels of 10 kV and below, with a total single installed capacity of no more than 6 MW.
The first category: less than 10 kV voltage level access, and a single network with a total installed capacity of not more than 6 MW of distributed power supply;
The second category: 35 kV voltage level access, the annual spontaneous use of more than 50% of the distributed power supply; or 10 kV voltage level access and a single grid connection point of total installed capacity of more than 6 MW, the spontaneous use of electricity more than 50% Distributed power supply
The third category: the access point for the public connection point, all generating capacity of the Internet power generation projects, small hydropower, in addition to the first and second category of distributed power. In line with the principle of simple and efficient grid and good service, the implementation of the State Grid Corporation of conventional power-related management requirements.
The first and second categories basically represent the roof-distributed and the land-based distributed projects, and the third type are the distributed projects corresponding to the full-scale internet-access mode.
What is the issue of distributed photovoltaic power generation is very important, we must study clearly, otherwise in the acceptance of power plants, will be limited to the nature of the project and subsidies.
