Analysis and Discussion on Technical Requirements for Operation of Photovoltaic Power Generation

The grid connection and operation of photovoltaic power generation in China follows the national standard GB/T 19964 Technical requirements for connecting photovoltaic power station to power system, released in 2012. This paper firstly interprets and analyze the clauses in this standard, including active/reactive power control, frequency control, voltage control and fault ride through. Then these clauses are compared with those in the standard of some countries in Europe and U.S., and the problems in application of these clauses in China are analyzed. Finally, the suggestions to improve the standard are proposed considering the technical developing trend of photovoltaic power generation in China.
