Abstract

The invention relates to a new energy power station primary frequency modulation capability testing system and a testing method thereof. According to the invention, data exchange between a fast communication interface module and a new energy power station plant-station level active / reactive power control system and a power grid is realized through building a new energy power station model a power grid model framework, a test scene is designed in a power grid model, frequency static characteristics of the power grid in different frequency bands are simulated, various responsive indicators of primary frequency modulation of a tested primary frequency modulation system of the new energy power station under frequency variations of the power grid are tested, and the capability of the new energy power station for participating primary frequency modulation is evaluated.

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 ...
