Combination of SVC with PV-Inverter for Voltage Regulation in Distribution Networks

in this paper, the static var compensator (SVC) combined with photovoltaic (PV) inverter system is suggested for completely solve the voltages deviations in distribution networks as a simplest method. The PV-inverter is playing a significant part in this voltage regulation control method. The SVC is integrated with the PV-inverter for permitting extra reactive power source. Therefore, they can successfully avoid voltage drop/rise produced by the loading and the intermittent PV generation system. A cooperative control technique can manage the reactive power capabilities of the PV-inverter and SVC. The 12.66 kV IEEE 33-bus distribution network is exploited to confirm the efficiency of the suggested integrated system. A certain complete day (24-hours) simulation is accomplished considering a variation of PV generation and presence different types of loads (domestic, industrial, commercial, and light). The results of simulation validate that the integrated control system succeeds in entirely eliminating the voltage deviations troubles with great PV penetration.
