*4.2. Voltage Control*

Capacitor banks, tap changers, voltage regulators, and static VAR compensators are equipment used to manage voltage during grid distribution. This is because DG injection makes the regulation of equipment at the substations useless, such as transformer tap changers, with many units scattered around the network selectively creating reactive power to allow for simpler voltage management. For example, a PV generator produces overvoltage at the network's end [43]. Therefore, implementing BESS in such cases has been proven to be effective and potentially reduce overvoltage [47,48].
