A SMC based Nine Switch Converter Topology for Reliable and Efficient Control of Hybrid Autonomous System

In this work a SMC based Nine Switch Converter topology has been used to integrate 2 different Renew able Energy Sources (RES) which feeds power to local time varying load. The Hybrid Autonomous System (HAS) consists of a 22Kw Self Excited Induction Generator (SEIG) based micro-hydro system and a Photovoltaic System. This system is also equipped with a Battery Energy Storage System and feeds power to a concentrated time varying load. The mere advantage of NSC is that it has a DC-link which helps in power control between SEIG and load. The major advantage of SMC based NSC is that continuity of power flow to the load is maintained even if the sources (SEIG & PV) are disconnected. Again the source side is unaffected if any disturbances is prevailed in load side. A couple of decoupled control strategy is designed for SEIG and load side control. This HAS is subjected to 3 different types of time varying loads i.e. Linear, Non-Linear and Dynamic Loads and their analysis is discussed. The above mentioned system was simulated and validated using MATLAB/Simulink environment.
