| Outline of Final Research Achievements |
In the project, a novel power conversion system for smart grid application was proposed, and the validity and effects of the system were demonstrated by simulation and experiment. The system consists of renewable energy source as a power source, a soft-switched buck chopper, electrical double layer capacitors (EDLCs) as a energy storage, and interconnected parallel current source inverters (parallel-CSIs). The soft-switched chopper realized the maximum power point tracking of the photovoltaic generation system and suitable energy charge to EDLCs. The parallel-CSIs also realized reactive power control for the suppression of the increased distribution line voltage caused by reverse power flow.
