摘要：The paper presents photovoltaic power systems interconnected with a power grid.Power generated by renewable energy sources tends to be unstable as it is affected by weather conditions.However,cooperation of solar Power stations with energy storage systems (e.g.electrochemical cells) significantly improves operational parameters and stability of the power system.Moreover,solar Power stations often operate at sites accessible for people,so they require galvanic isolation between the cells and the power grid.As the PV plants are required to maintain high energy conversion efficiency,the energy conversion is carried out with resonant power electronic converters with very low energy losses.Another significant component of the system is the line-side converter which transmits electricity from photovoltaic cells to the grid.
