摘要：

The connection of high proportion of wind power into the power system results in the reduction of the system inertia and the primary frequency regulation capability, which may highlight the issue of frequency safety under power disturbances. Therefore, the frequency safety constraints need to be considered in the unit commitment. First, a simple and practical frequency safety constraint is proposed. When the system satisfies this constraint, the maximum frequency deviation under a given power disturbance remains in the set range. By incorporating this constraint into the unit commitment model, and on the basis that the system can still bear the corresponding power disturbances when the wind power output is in the extreme case, an unit commitment model is established considering the wind power uncertainty and the frequency safety constraints. Simulation results show that the proposed unit commitment model takes into account the uncertainty of wind power, and can also meet the frequency safety needs of the system under high power disturbances. © 2021, Power System Technology Press.
