Modeling of power-supply subsystems of microgrid using Petri nets

The modeling of power-supply systems such as photovoltaic system and wind-power system by using Petri nets was considered. The models were created for different inputs conditions such as states of photovoltaic elements and of accumulator battery, wind power, power of loads and for different combinations of these conditions. These models are the base for creating of flexible algorithms for control of electric energy flows in microgrid subject to some optimization criterions.
