Development and performance analysis of Electrical Spring with intermittent renewable energy sources using advanced controller

Electricity is being produced in large amount with power plants with coal, oil as primary source and use of these fuels results in increasing pollution and green house problems. Day by day increasing consumption of these fuels is leading towards the extinction of these conventional fuel sources. Now a days nonconventional energy sources are being installed in modern power systems worldwide to solve the crisis of fossil fuels. But the penetration of these non-conventional sources in the power system affects the quality and stability of system in adverse manner. This paper presents an effective concept called Electrical Spring to regulate the mains voltage despite of fluctuations caused due to intermittent nature of renewable energy sources using different types of control techniques. This technology reduces the voltage fluctuations on grid and stabilizes the power system with substantial penetration of intermittent renewable energy sources.
