Introduce the grid-connected technology and application examples of distributed power supply.
The commonly used grid-connected control of photovoltaic systems mainly includes two closed-loop control links: the maximum power point control link and the output waveform control link. 1. Maximum power point control link According to the output characteristics of photovoltaic cells, under certain sunshine intensity and temperature, the output power of photovoltaic cells can reach the […]Read More
Distributed wind power and photovoltaic power are the main components of distributed power, usually connected to medium-voltage or low-voltage power distribution systems, which can effectively make up for the lack of large-scale centralized power generation and transmission. The grid-connected distributed generation system has the advantages of effectively utilizing electric energy, but it must meet the […]Read More
Grid-connected equipment selection (1) General principles. The selection of engineering equipment for distributed power supply access to the user’s distribution network should follow the following principles: ① Distributed power supply access system engineering should select equipment whose parameters and performance meet the safe and reliable operation of power grid and distributed power supply. ② The […]Read More
The voltage level connected to the distribution network The grid connection point of the distributed power supply refers to the connection point between the distributed power supply and the power grid, and the power grid may be a public power grid or a user power grid. The legend of the grid connection point is shown […]Read More
