To prevent the overvoltage in high PV penetration conditions, EESS can be applied in order to store a part of the energy generated by PVs and limit the amount of active power injected into the grid by PV units.
In residential feeders, in which the load consumption is relatively small during high PV generation periods, the potential for overvoltage is greater, and a lower share of PV systems may cause reverse power flow and an unacceptable voltage rise in the grid.
Coordination of EESSs and active and reactive powers of PV inverters through a combination of localised and distributed control methods can minimise the active power curtailment and prevent the overvoltage while reducing the energy storage need .
However, overvoltage is the main challenge in many LV grids with PV, and is one of the main limiting factors in increasing PV penetration in LV grids. Overvoltage caused by PV systems happens when the power flow path is reversed from customers to the LV transformers.
Electrical energy storage application has a high potential for overcoming the challenges associated with PV systems, and, in addition to its application for overvoltage prevention, it can be used to prevent the overloading of the grid components and trade power in electricity markets.
Grid reinforcement is suggested as a solution to improve the voltage profiles of customers in the condition of high EV penetration. In a similar way, grid reinforcement seems one of the most effective methods for solving the overvoltage issue in high PV generation conditions .
