This paper presents the analysis of voltage profile and active power losses in a low voltage distribution network (0.4 kV) with connected prosumers that have installed photovoltaic (PV) power plants in their houses. A computer model of three radial low voltage feeders is created in DIgSILENT PowerFactory software for simulation purposes. The analysis is done for various scenarios of PV active and reactive power production. Conventional as well as optimal power flows (OPF) are analyzed and compared. In two scenarios, optimal power flows are used to optimize voltage profile and losses using PVs reactive power injections. The obtained results indicate that the OPF did not achieve a significant reduction in active power losses. However, a noticeable improvement in voltage profile is accomplished regarding conventional power flow. |
