A Study for Integrated Measures for Installation of Photovoltaics by Stochastic Analysis of Hosting Capacity in Distribution Networks

Abstract

Though installation of photovoltaic (PV) systems already exceeds 40GW, more and more PV will be needed for de-carbonization. The capacity of PV will be several times of the load or more, especially in rural area distribution feeders. This paper proposes integrated measures for such PV installations which combine grid reinforcement and PV power factor control. The reinforcement includes not only replacing to heavier lines, but also using 22kV lines partially. Hosting capacities are analyzed stochastically to evaluate and compare the impact of these measures.
