The power factor and total harmonic distortion (THD) are important considerations when designing an output filter. In the case of the photovoltaic (PV) ac-module, the size and weight also have to be taken into consideration. This paper proposes an output filter to reduce size and weight, and provides the optimal design method for a PV ac-module. The proposed output filter consists mainly of a conventional...
Because AC module system is directly connected to grid source, power pulsation is appeared at AC module input capacitor. So, it can adversely affect maximum power point tracking (MPPT) control. Furthermore, photovoltaic (PV) module power can be fluctuated with varying irradiation while constant load demand. To reduce power fluctuation for MPPT control and stabilize the PV system with varying conditions,...
Recently, active power decoupling method is studied for reducing power oscillation on PV (Photovoltaic) module by grid side instantaneous power. However decoupling circuit input current delay and inverter system efficiency affect power oscillation when decoupling circuit is operating. This power oscillation disturbs MPPT (Maximum Power Point Tracking) control. To reduce power oscillation considering...
