Abstract

Increasing penetration of distributed renewable energy resources (DRES) and smart loads into the LV network lead to new power quality challenges. Important power quality challenges are overvoltage and undervoltage. A number of solutions are already developed to mitigate these voltage variations. In this research, On Load Tap Changer (OLTC)-based control technique is used to mitigate overvoltage and undervoltage. A specific voltage variation case is assumed in this research, in which, both overvoltage and undervoltage occur simultaneously. In this paper, a solution to mitigate the aforementioned voltage problems is proposed. Importantly, the proposed control is capable of mitigating both overvoltage and undervoltage simultaneously. The solution includes coordination of OLTC and the photo voltaic systems. Furthermore, the proposed control is verified using a co-simulation platform.
