Abstract：Stability is an important element to be considerated in the design and analysis of isolated power system. Due to the conservatism of the existing stability criterion, which makes the isolated power system cost a lot for stable operation. Tighter restrictions are also put forward for system cascade. In this paper, consider the gain margin and phase margin constrain at the same time and deduce the stability criterion with smaller forbidden region to calculate generalized impedance constraint set and generalized load admittance set of the multi operating point system. An isolated power system consisting of a synchronous machine with a rectifier as a source and a constant power as load is analyzed by using the proposed method and which compared with existing method shows it can get more accurate results and reduced conservatism effectively.
