Abstract

Variable renewable energy integration makes the revolution in modern power system operation and control which lead to perform the preventive and corrective control for maintaining the system continuity againts the voltage security and instability. On the other hand, the power system utility should maintain the economical aspect for its operation, which is hard to be obtained in the system prioring the preventive and corrective scheme. This paper proposes the optimal management between preventive and corrective scheme for achieving the most economical operating cost to solve a stochastic security-constrained optimal power flow for the upcoming time-slot considering voltage stability, line contingency occurence and renewable energy source fluctuation by controlling the generation power, compensator and load shedding scheme while maintaining the computation speed. The main contribution of the proposed method is the active control between preventive and corrective schemes simultaneously for achieving the most economical solution. Scenarios developed in modified IEEE 57-bus test system are used to demonstrate the effectiveness of the proposed method. The simulations show that the proposed method can make a significant contribution for achieving more economical solution while maintaining the computation speed.
