ESS are designed to improve the quality and stability of electricity before it is delivered to the load.

Consequently, the PV system fully satisfies the load’s power demand and any surplus of power will be stored in the battery. From t = 1.2s to t = 2s, the power generated by the PV system is lower than the load power requirement, and this depends on the level of irradiation.
PP Optimization Application to PI Controller Tuning PP, also called full-state feedback, is a technique used to control various closed-loop parameters such as overshoot, peak time, rising time, and settling time [45, 47 – 49].
The power generated by the PV system is presented in Figure 15, which shows that the power produced by the PV system is directly linked to the solar irradiation profile, thus highlighting the significant impact of the irradiation level on the energy production of the PV system.
