Incorporating Power Angle Stability and Frequency Stability in Generation Optimization Planning with High Renewable Energy Penetration

With the high renewable energy(RE) penetration, the power system is facing more and more stability issues. Among them, the power angle stability(PAS) and frequency stability(FS) have close association with the power generation status. A generation optimization planning method integrating PAS and FS is proposed in this paper, which incorporates the power angle stable cut constraint obtained through PSAT based on EEAC, and frequency stable cut constraint obtained through Simulink based on equivalent frequency response model, achieving the stability requirement while ensuring economic efficiency. The approach collaborates the construction of thermal power units, wind power, solar power and energy storage using the column and constraint generation algorithm. The advantages of the proposed approach are validated through a provincial power system in China.
