Design and Implementation of an Voltage Compensation with SSSC for Distributed Energy Systems

Today’s modern interconnected power system is highly complex in nature. Reliability and security are one of the most necessary requirements of an electric power system during the normal operation. Wind Energy Conversions Systems (WECS) has reached a level of most importance during recent years. A primary source of distributed generation systems has the variable speed wind turbines along with a direct driven PMSG and power electronic interfaces. These are the most frequently used systems that are displaying the variability in output power levels as a result in change of the prime mover speed. When the grid is interconnected with such a configuration then it will introduce various challenges to the network related to stability, power quality and voltage regulation issues. It can cure by providing modern power electronic devices known as FACTS (Flexible AC Transmission System) devices, along with their controllers. Among the FACTs device, Static synchronous series compensator (SSSC) due to high speed changes its reactance characteristic inductive to capacitive, is effective power flow controller and proposes a Sliding Mode Controller (SMC) for FACTS controller which has the ability to withstand all the faulty conditions that are taken into considered. The Stability of WECS can be enhanced by using a FACTS based device which is a Static Synchronous Series Compensator (SSSC) that can improve the voltage compensation capability.
