With the high penetration of renewable power in the power system, the inertia level and frequency regulation capability are reduced, the system frequency safety are facing a major challenge. Considering the different frequency support capability of the synchronous generators, the effect of adjustment coefficient of different units on the minimum frequency has been analyzed based on the sensitivity analysis. A multiobjective frequency constraint unit commitment model considering the sensitivity of adjustment coefficient is proposed, and simulation results show that the proposed model increases the minimum frequency value, improves the frequency stability of the power system.
Key words: unit commitment / frequency response / adjustment coefficient / frequency constraint
