A Study on Maximum Potential of PV Installation Considering Bus Voltage Constraints

—An Impact of Pre-specified PV Installation on the Maximum Potential—

Abstract

This paper presents an impact study of pre-specified PV installation and network configuration on the maximum PV potential in distribution networks. Although there is an optimal solution for installing PV systems to achieve the maximum potential of PV installation under a bus voltage constraint in a distribution network, the practical installation of PV systems may not exactly equal to the optimal solution. A sensitivity analysis of maximum PV installation by varying a pre-specified PV installation capacity at a particular bus is performed to investigate the impact on the change of PV installation capacities at other buses and on the degradation of the maximum potential of PV installation of a distribution network. The impact of pre-specified PV installation is also considered in different configurations of the distribution network. Finally, decisions for the PV installation in a distribution network are discussed.
