Coordinated Voltage Control in Distribution Systems with Distributed Generations

This paper presents a centralized coordinated voltage control algorithm for distribution systems with distributed generations (DGs). The control algorithm coordinates the use of available distributed generation (DG) with the traditional voltage regulation devices, taking into consideration the reactive power limits of the DG inverters to maintain the system voltage within predefined limits. With the help of the developed algorithm the reactive power generation capacity of the DG inverters can be used to cope with the dynamic generation of the DGs without increasing the operations of the traditional voltage regulation devices available.
