Dynamic and Reliable Power Control Scheme for a Hybrid Autonomous System using a M-FLC based Nine Switch Converter

摘要

In this proposed work, a hybrid autonomous system (HAS) is considered. The HAS consist of a micro-hydro based 22KW self-excited induction generator, a photo voltaic system of 18KW and Mamdani-Fuzzy Logic Controller based Nine Switch Converter which is assembled with a BESS. This entire system dynamic response is studied by subjecting it to local time varying loads (linear, non-linear, dynamic). The benefits of fuzzy logic based Nine Switch Converter are discussed. The uninterruptible PS to the load is also investigated by detaching Self excited induction generator system & Photovoltaic system at different time intervals. Two different methodologies for independent control strategy are designed, firstly for source side voltage and frequency and secondly for load side voltage and frequency. The entire system is modelled with the use of MATRIX Laboratory environment.
