Performance analysis of a hybrid power system with three phase interleaved bidirectional converter

A utility interface converter is one of the key components in the hybrid power systems. This Paper addresses a novel three phase interleaved bi directional power converter circuit for economical solar, wind & battery hybrid power system (HPS). HPS consists of both AC and DC networks connected together by three phase interleaved bi directional converter in combination with 3phase pulse width modulation controlled converter. Here PWM controlled converter switches are used for smooth power transfer between AC and DC links and to maintain stable operation with various renewable sources (Both AC and DC), different loads. The addressed hybrid architecture is very flexible to decrease the required power conversions stages and hence the system cost and efficiency. The HPS is simulated in MATLAB/Simulink Environment and the simulation results show that the system can maintain stable operation with three phase interleaved bi directional converter both in the grid tied, autonomous modes.
