Abstract

A high penetration of solar photovoltaics will result in the voltage violations in residential distribution networks. In addition, increased power demand during peak load conditions exacerbates the risk of extreme voltage violation. Enhanced voltage regulation and reactive power control is difficult to be achieved by a centralized control as they are limited by communication and computational burden. In contrast, local voltage regulation is based on measurements in real-time and will have a faster response to the PV power fluctuations and its associated stabilization of the system. This paper proposes a local voltage control strategy based on the reactive power capability of PV inverters. A Q-V based control curve is formulated for the PV inverters and further to ensure its faster response, tuning parameters based on active power and bus voltage measurements are introduced. Considering different value of R/X ratio, the proposed control strategy has been evaluated for urban and rural residential distribution network.
