Description

technical field [0001] The invention relates to the technical field of new energy power generation, in particular to a primary frequency modulation control method and system for a new energy power station. Background technique [0002] As an important index to measure power quality, grid frequency is related to the normal operation of electrical equipment and the quality of power consumption of users. When the power system is running, the real-time and random changes in the power system load will cause real-time and random fluctuations in the grid frequency. With the continuous expansion of the grid scale, new energy power sources have become the main power source of the grid. In order to ensure that the grid can fully absorb new energy power generation, the output of thermal power units has been continuously reduced. In some areas, the number of thermal power plants has even been reduced. This reduces the system inertia. Frequency volatility is getting worse. After retrie...
