The major role of power system is voltage stability. It is required to plan properly and smooth operation and control. It presents a new approach of voltage stability improvement in IEEE 57 bus system using hybrid algorithm. The hybrid algorithm (PSO-MVO) is combination of PSO which is used for exploitation and MVO used for exploration. It is used in an uncertain environment. The FACTS device as STATCOM is connected in IEEE 57 test system to check for event of voltage stability improvement through power system analysis tool (PSAT) software. Once the ability of system goes through sudden loading, its stability gets affected. It desires compensation to boost voltage from disturbances. The varied operative condition while not used STATCOM in the system, used with STATCOM tuned by PSO-MVO algorithm are measured judge the performance of the projected system. The hybrid PSO-MVO technique is implemented in this paper to solve the proposed problem. The simulation results are obtained by PSAT software for 57 IEEE bus systems. The hybrid algorithm validates its effectiveness compare to individual PSO and MVO algorithm.

It studies the changing regulation of fast out-of-step separation criterion based on equivalent two-machine power system. Analysis of the characteristics of the caring variables of fast out-of-step separation criterion on sending end and receiving end is mentioned. In order to solve the problem that the out-of-step connecting line cannot be identified correctly apply on the criterion of the existing fast out-of-step separation if the measurement point at the receiving end, it improves the power angle and active power criterion. The simulation is carried out in our actual grid model with using BPA and the results of the simulation handled by MATLAB proves that the out-of-step of line can be distinguished by using the improved fast out-of-step separation criterion in each end of line.
