Abstract

It is a defect that PV power generation is only useful for clear daytime conditions. However, a new 24 hours application as an extended area can be added by the active utilization of the potential ability of PV power conditioners. For this purpose, a new multi functional power conditioner was developed which has a smoothing function to reduce PV output variation and load fluctuation, and also has additional function to compensate harmonics current and reactive power caused by customer´s load. As a result of indoor testing, a reduction rate of 1/5 for harmonic currents and 1/7 for reactive power were achieved. In addition, a 1/10 reduction rate for smoothing of PV output variation and load fluctuation was observed. The work has been promoted by NEDO as a part of New Sunshine Project in Japan
