The key function of a battery in a PV system is to provide power when other generating sourced are unavailable, and hence batteries in PV systems will experience continual charging and discharging cycles. All battery parameters are affected by battery charging and recharging cycle.
In power system applications, battery energy storage systems (BESSs) were mostly considered so far in islanded microgrids (e.g., ), where the lack of a connection to a public grid and the need to import fuel for conventional generation makes it convenient to store surplus electricity from local renewables to use during generation shortfalls.
The uncontrolled charging–discharging method is very simple and directly exposes the grid. In this method, the grid operator does not receive any user information about the system, which may result in problems with grid stability, power quality, operational efficiency, and battery state-of-charge (SOC).
All battery parameters are affected by battery charging and recharging cycle. A key parameter of a battery in use in a PV system is the battery state of charge (BSOC). The BSOC is defined as the fraction of the total energy or battery capacity that has been used over the total available from the battery.
The charging/discharging current of a battery cell is expressed in terms of its C-rate, which is defined as the current in ampere (A) over the cell energy capacity in ampere-hour (Ah). Power-rating-to-energy-capacity ratios of commercially available BESS are generally between 0.75 and 2.
Intelligent charging–discharging refers to a system whereby a data connection is shared between an EV and a charging station, and the charging station is connected to a transmission/distribution system operator.
