In recent years, renewable energy power generation has developed rapidly in China. However, renewable energy resources represented by wind energy and solar energy are random, volatile, and intermittent, and are affected by their power generation equipment. Large-scale renewable energy generation and grid connection will have certain impacts on some areas of power system and sometimes even the entire system. The renewable energy grid-connected technology is a key technology to solve the renewable energy development problems. Therefore, on-site grid-connected testing of renewable energy power station is of great importance.
Ti Balun is committed to the testing activities related to renewable energy power station acceptance and grid-connected performance, and has the corresponding technical capabilities and experience.
