This paper presented a new approach to address the frequently encountered Standing Phase Angle (SPA) reduction problem during a power system restoration process. The proposed method was based on a modified Genetic Algorithm (GA). The problem of the SPA reduction was modeled as a mixed discrete-continuous optimization problem with various constraints. The objective function that needed to be minimized...
The control strategy of sustained over-voltage during the early stages of power system restoration is studied and a new method is presented in the paper. According to the results of load flow calculation and sensitivity analysis, the method applies expert system technique and non linear programming in turn to solve the control scheme of sustained over-voltage for each target bus. Differences between...
