Isolated Wind Hydro Hybrid Generation System with Battery Storage
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 3
Abstract
In this paper, a new isolated wind- hydro hybrid generation system comprising one squirrel - cage induction generator (SCIG) driven by a variable-speed wind turbine and another synchronous generator driven by constant power hydro turbine feeding three phase four wire local loads is proposed. The system utilizes two back to back connected voltage-source converters (VSCs) with a battery energy storage system at their dc link. The main objective of the control algorithm for the VSC is to achieve control of the magnitude and the frequency of the load voltage. The proposed wind-hydro hybrid system has a capability of bidirectional active- and reactive-power flow, by which it controls the magnitude and the frequency of the load voltage. The proposed electromechanical system is modelled and simulated in MATLAB using Simulink.
