Abstract: To address voltage violations introduced by the extensive integration of DERs into distribution power grids, a voltage control system is provided to maintain the proper voltage levels essential for a stable and reliable distribution power grid. The voltage control system uses a two-stage approach. In the first stage, the system regulates voltage at the local level, typically at the consumer's premises. Local level control relies on the flexibility of various DER systems, such as EV charging systems, photovoltaic systems, and battery energy storage systems, which can be controlled and adjusted to maintain stable voltage levels within acceptable limits. In the second stage, distributed control is implemented by coordinating distributed voltage-regulating devices such as PV inverters, OLTCs, and capacitor banks to control network voltage in real time.
