Despite the individual merits of solar and wind energy systems, their intermittent nature and geographical limitations have spurred interest in hybrid solutions that maximize efficiency and reliability through integrated systems.
In nature, an intermittent characteristic of the wind speed and solar irradiation makes these sources unpredictable, and hence, energy produced by wind and PV system generates uncertain conditions in operation of microgrid. In such cases, the security and reliability of microgrid are enhanced by integration of energy storage system (ESS).
Scheme of PV + WT on grid (a) off grid (b) scenario. The combination of PV and WT systems in an integrated energy storage the model equations for such a system: Both PV and WT power production described in section 2, the energy balance equations for this scenario can be described: For on-grid system (18) P g r i d = P l o a d (P P V + P W T)
In such cases, the security and reliability of microgrid are enhanced by integration of energy storage system (ESS). This work deals with an energy management in a hybrid system incorporating PV source and permanent magnet synchronous generator (PMSG)-based wind energy system.
