This paper furnish the new Metaheuristic algorithm called Cuckoo Search Algorithm (CSA) for solving optimal power flow (OPF) problem with minimization of real power generation cost. The CSA is found to be the most efficient algorithm for solving single objective optimal power flow problems. The CSA performance is tested on IEEE 57 bus test system with real power generation cost minimization as ...

An online auxiliary control was designed for Static Var Compensator (SVC) to improve the poorly damped oscillations in multi-machine power system subjected to small and large disturbances.

This paper demonstrates the enhancement of inter-area mode damping by multiple flexible ac transmission systems (FACTS) devices. Power system damping control design is formulated as an output disturbance rejection problem. A decentralized damping control design based on the mixed-sensitivity formulation in the linear matrix inequality (LMI) framework is carried out. A systematic procedure for s...

This paper proposes an efficient optimization approach to determine the optimal placement and size of Static VAR Compensator (SVC) in a hybrid power system. The hybrid power system consists of conventional thermal generators, wind farms and solar photovoltaic (PV) modules. In this paper, the optimal placement and size of SVC is determined by considering the voltage deviations minimizations and ...
