This paper proposes an approach coupling security-constrained optimal power flow with time-domain simulation to determine an optimal combination of preventive and corrective controls ensuring a voltage stable transition of the system towards a feasible long-term equilibrium, if any of a set of postulated contingencies occurs. A security-constrained optimal power flow is used to adjust the respective...
Network optimization especially in power industry is one of the main goals of system engineering. It not only reduces the cost of the system but also improves its stability. Among various methods of optimal control of power networks, like Linear Optimal Control (LOC), a model-based adaptive optimal method has been presented here which can also be used in multi machines systems with multimode high...
This paper represents an alternative approach on designing PSS for a single machine and infinite bus (SMIB) system based on sliding mode control (SMC) technique. SMIB system is chosen as it is such a simple configuration which is extremely useful in understanding basic effects and concepts of PSS. In order to test the effectiveness of the proposed scheme, simulation will be carried out to analyze...
