Performance comparison of bidirectional converter designs for renewable power generation

This paper aimed at comparing the performance of bidirectional converter designs for renewable source power generation such as wind. The bidirectional converter is supposed to allow a bidirectional power flow between power line and a battery system. In order to determine the most applicable bidirectional converter circuit which meets a set of requirements, four types of designs which were based on previous work of others were simulated with PSCAD software. The ability of each design to maintain a set voltage at the power line and also the direction of current flows at the battery as well as at the output of the converter are investigated.
