Abstract

The generator reactive power reserve is closely related to the power system voltage stability. The voltage stability margin can be effectively improved by improving the critical generator reactive power reserves. A static stability preventive control approach based on reactive power reserve sensitivities is presented. The proposed approach can be divided into a sensitivity computation sub-problem and a sensitivity-based quadratic programming optimization sub-problem. In the previous sub-problem, critical generators are identified by calculating the load margin and sensitivities of generator reactive power reserve are calculated. In the latter sub-problem, the most effective control actions are selected to improve the computation efficiency of quadratic optimization problem. Simulation results on IEEE 30-bus power system indicate that the proposed method is effective.
