Power Flow Analysis on Networks with High Integration of Distributed Photovoltaic Generation

This article proposes the use of a controlled current source as a photovoltaic generator, due the fact that recent work shows that this choice provides faster processing speed and agile implementation to obtain the power flow. This phasorial analysis will be tested using, with some considerations, the 13-Node Test Feeder topology and its input data. Initially, no distributed generation will be considered connected to the feeder and, for a second analysis, photovoltaic distributed generation will be inserted in the system to perform the power flow calculation with the proposed model. The reference simulator will be the Knowledge's Virtual Academy (KVA), because it is a free-access software with a high-level solver to perform the numerical calculation. While the proposed methodology will be implemented in the software Matlab. This study compares and analyze the voltage magnitude, mainly, and angle values obtained for both methods, the KVA result and the proposed method, for the scenarios with and without distributed generation.
