摘要：With the rapid development of new energy sources such as wind power and photovoltaics, and the intensification of interconnected power grids, power fluctuation problem brings adverse influence on power grid frequency control. The stability of power grid frequency mainly depends on primary frequency compensation (PFC) of thermal power units. How to control and improve the PFC ability is the precondition to realize the safe and stable operation of power grid. By analyzing the PFC assessment system and standard of power grid, the problems in the current unit's PFC were pointed out. By dynamically correcting the current rotation difference according to the actual main steam pressure measurement value of the unit, it can fully compensate the grid power gap by using the unit's heat storage. The application results show that the power-friendly PFC method and system of receiving-end grid can effectively control the thermal power units to achieve the stability of power grid frequency.
