Hybrid Isolated Wind–Hydro System by Using Induction Generators and Battery Storage
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 6
Abstract
Now a days Most of natural energy sources such as wind, geothermal, solar, biomass, and hydro show predominance for energy production. Out of these natural energy sources, small wind and small hydro energy which are complements each other. induction generators (SCIGs) is used to Power generation by wind as well as hydro systems. The wind turbine in recent year which has switched from fixed variable speed as later has advantages of 1) dynamically balance for power pulsations,torque 2) reduce in mechanical stresses,3) improves power quality 4) system efficiency. There are however some isolated locations where hydro and the Simultaniously exist the given wind potential but these cannot connected to thepower station i.e. Grid. For these locations , a “innovative isolated hydro wind hybrid system by using battery storage and cage generators” is presented in this paper. It employs two SCIG out of these two SCIG; One squirrel-cage induction generator (SCIG) is drive by a wind turbine having variable-speed and other SCIG driven along with constant-power hydro turbine BESS which feeds loads having four leg three phase system. To achieved maximum power tracking (MPT) Control technique is implemented for the VSCs . under variable wind speed using wind turbine with the help of rotor speed we can achieve maximum power. We can achieve it with controlling load voltage and frequency.Bidirectional power flow control is proposed in this paper.this proposed system analysis we did with the help of variable load and variable speed wind speed.
