Optimal SVC placement for maximizing photovoltaic hosting capacity in distribution network

Abstract

It has become a challenging task to accommodate the proliferation of distributed photovoltaic (PV) generation in distribution networks (DN). In order to enhance the PV generation hosting capacity (HC) in DN, we propose a novel optimal static VAR compensator (SVC) placement model in this paper. The objective is to maximize the PV admissibility and minimize investment cost of SVC while maintaining required levels of power quality and system stability. To reduce the complexity of the problem, linearization is utilized to transform the original nonlinear problem into a mix-integer linear program. Finally, the effectiveness of the proposed model is validated using a modified IEEE 37-bus distribution system with excessive PVs.
