| 英文摘要 |
| 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. |
