Abstract

The photovoltaic power plants (PVPP) have various applications. PVPPs are used for household applications,
electricity production in off-grid systems, electric consumption reduction from the power grid, generation of
electricity to the grid, etc. Solar energy is a primary energy source which can be converted into electricity. This
type of energy source is highly dependent on the weather conditions, or in other words, they are intermittent.
PVPP without supporting devices could not produce electricity directly for the energy market, since they would
have too large deviations between the traded and produced electricity, what would lead to high financial penalties.
Batteries are one of the possible solutions to overcome the intermittent electricity production from PVPP, by
controlling the energy output. Collaboration of PVPP and battery storage systems would potentially enable a
direct energy production of the PVPP on the market, and new operating options.
