Prevention of Transient Instability and Reactive Power Mismatch in a Stand-alone Wind-diesel-tidal Hybrid System by an ANN Based SVC

Abstract

This paper gives a novel idea of application of ANN based SVC controller for Reactive Power compensation in an isolated hybrid system and also discusses the improvement of stability in the hybrid system. For detailed analysis a small signal linear model of the hybrid wind- Diesel- tidal model is considered with different loading conditions. The reactive power compensation and stability analysis have been thoroughly analysed by a SVC Controller. A feed forward neural network with back propagation technique is designed to tune the parameters of SVC controller. Simulation result shows that the system parameters attend steady state value with lesser time and complexities.
