Description

technical field

[0001] The invention relates to a primary frequency modulation capability testing technology of a new energy power station, in particular to a primary frequency regulation capability testing system and a testing method for a new energy power station. Background technique

[0002] As of the end of 2015, the installed capacity of wind power in the country reached 129 million kilowatts, and the installed capacity of photovoltaic power generation reached 43.18 million kilowatts. In many provinces and regions in Northwest China, the penetration rate of new energy power generation has exceeded 30%, becoming one of the main power sources. In order to ensure the safe and stable operation of the power grid under the condition of fully consuming new energy power generation, it is necessary to fully grasp the ability to test the frequency response of new energy power generation.

[0003] At present, more and more new energy power stations have the capability of primary ...
