【 摘 要 】

The construction of large-scale renewable energy sources has caused challenges to frequency stability of power system. This paper presents a method to evaluate the frequency stability of power system with high penetration of renewables. Based on input-to-state stability (ISS) theory, security/stability indices reflecting the frequency stability of the system are established. In addition, a simplified analysis method of local input-to-state stability (LISS)/ local input-to-output stability (LIOS) attributes is proposed based on System Frequency Response (SFR) model. Case studies are performed to verify the validity of the proposed method, and the corresponding security/stability indices are calculated.
