This research has analyzed the current status of hybrid photovoltaic and battery energy storage system along with the potential outcomes, limitations, and future recommendations. The practical implementation of this hybrid device for power system applications depends on many other factors.
The PV unit and battery storage system both operates to minimize the demand profile optimally and economically. The peak shaving technique can control the charging/discharging mechanism of the battery storage system to maintain optimal operation.
The major findings of the simulation case study on the peak shaving strategy are presented as follows: The existing peak shaving strategy can minimize the peak demand using a photovoltaic and a battery storage system. The PV unit and battery storage system both operates to minimize the demand profile optimally and economically.
Considering the advantages and disadvantages, BESS is the most promising energy storage system to integrate with the PV system to mitigate the power fluctuation and power-related issues arising from PV unit , .
PV system based on operation and applications Photovoltaic systems are classified into two categories based on the operations and applications which are stand-alone PV systems and grid-connected PV systems , , . The PV systems can operate independently or can be interconnected with the utility grids.
The photovoltaic installed capacity set in the figure is 2395kW. When the energy storage capacity is 1174kW h, the user’s annual expenditure is the smallest and the economic benefit is the best. Fig. 4. The impact of energy storage capacity on annual expenditures.
