  • In this paper, novel concept of a photovoltaic(PV) power generation system adding the function of active filter(AF) is proposed. Even PV power generation system can be treated to a harmonics source for the power distribution system, it is necessary that the function of AF system in grid connected PV power generation system. Active Filters intended for harmonic solutions are expending their functions from harmonic compensation of nonlinear loads into harmonic isolation between utilities and consumer, and harmonic damping throughout power distribution system. So, the PV system combined the function of AF system can be usefully applied in power distribution system. Here, the control strategy of PV-AF system is introduced.

  • The photovoltaic(PV) industry has been growing worldwide. Recently, the PV industries not also in the traditional PV advanced countries but also in other countries are rapidly growing. Especially, China has become the largest supplier in the world PV supply side since 2007. Both the world PV supply and demand rose steadily in 2008 like recent bumper years. In 2008, the world solar cell production reached 6.85GW~7.91GW presenting growth of 85% over the previous year. On the demand side, 81 countries contributed to the 5.95GW presenting growth of 110% over the previous year.

  • So far, because the photovoltaics power generation system can be treated to a harmonics source for the power distribution systems, the PV system combined the function of AF systems as well as the AF systems using the PV module as the power source have never been reported. However, authors have recently proposed a novel concept of the photovoltaics power generation system adding the function of the active filter (PV-AF system). In this paper, in order to confirm the operational characteristics of the PV-AF system, various MPPT controls are applied and analyzed.

  • Operation modes and control strategies for single-phase mobility charging station utilizing photovoltaic (PV) generation and energy storage systems (ESS) are proposed. This approach generates electric power from PV to transmit the mobility, ESS, and then transfer it to the grid when surplus electric power is generated during daytime. However, the PV power cannot be generated during night-time, and ESS and the mobility system can be charged using grid power. The power balance control based on power fluctuations and the resonant current control that can compensate harmonic components have been added to increase the stability of the system. The MATLAB/Simulink simulation was carried out to verify the proposed control method, and the 2-kW single-phase grid-tied PV-ESS smart mobility charger was built and tested.
