- Abstract
With the continuous increase of the proportion of renewable energy power generation connected to power system, the power system has put forward specific requirements for the primary frequency modulation of the renewable energy power generation system. The frequency droop coefficient is an important index for evaluating the amount of primary frequency adjustment of the renewable energy power generation station. The frequency droop coefficient of the system for the renewable energy power generation station is preset. However, when the frequency of power system fluctuates, it is impossible to predict the operation status of the renewable energy power generation station. Under a single control parameter, the renewable energy power generation station cannot guarantee that the frequency modulation amount can meet the system requirements. Therefore, a real-time correction method for the primary frequency modulation control parameters of the renewable energy power generation station is proposed, based on the closed-loop control of the frequency modulation. According to the operating state of the renewable energy power generation station, the frequency droop coefficient is adjusted in real time, so that the renewable energy power generation station can meet the frequency regulation requirements in different states and support system frequency stability.
