MicroGrids (MGs) are one of the possible alternatives to efficiently include RESs in the main utility grid. An MG is a small-scale power entity which includes local loads, RESs-based distributed energy generation, such as PhotoVoltaic (PV) modules and wind turbines, and Energy Storage Systems (ESSs), e.g., lithium-ion batteries [3].

Solar battery storage systems operate best within a specific temperature range. Extreme heat or cold can affect the battery''s performance and lifespan. Ensure that your battery is in a location that stays within the recommended temperature range. If necessary, consider installing insulation or cooling systems to regulate the temperature. Check
Several energy storage systems have been introduced in the practice however, the storage by battery is still widely used due to its low cost and its simple maintenance. However, the continuous changes of metrology conditions give a random change in the battery inputs (current and temperature) which make it complex in terms of modeling, control and real-state

In a standalone photovoltaic system battery as an electrical energy storage medium plays a very significant and crucial part. It is because in the absence of sunlight the solar PV system won’t be able to store and deliver energy to the load.
Guidelines under development include IEEE P2686 “Recommended Practice for Battery Management Systems in Energy Storage Applications” (set for balloting in 2022). This recommended practice includes information on the design, installation, and configuration of battery management systems (BMSs) in stationary applications.
Batteries with a large charge-discharge cycle are the most suitable for the application of a standalone PV system. Other factors that add up to the selection of the battery are the cost and availability of the batteries. Before choosing a battery, we need to make sure its availability in the market.
Such rechargeable batteries with many cycles are widely applicable in solar PV applications as they ensure the continuity of the power to the load in the presence of low or even no sunlight, without which the implementation of a standalone solar PV system would be very unreliable and difficult.
