Description

technical field [0001] The present invention relates to a primary frequency modulation control system and method, in particular to a primary frequency modulation control system and method for grid power flow section partition control. Background technique [0002] Nowadays, with the rapid development of wind power, photovoltaic and other new energy power generation, the power structure has undergone major changes, and the impact of new energy power generation has developed from simple local voltage fluctuations, harmonic pollution and other power quality issues to power grid safety issues. The available primary frequency modulation response resources of the power grid are gradually decreasing, resulting in a further increase in frequency security risks. In recent years, new energy stations have also gradually participated in the primary frequency modulation work of the power grid. [0003] The main reason for the instability of the interconnected grid is that the power trans...

Problems solved by technology

[0004] The above reasons lead to the simultaneous input of the primary frequency modulation function of multiple power sources in multiple sections. When the frequency of the power grid deviates, various regions and power sources cannot coordinate with each other, which will lead to fluctuations in the frequency of the power grid or even oscillation and divergence, threatening the power grid.
