Test of Advanced Functionalities of Photovoltaic Inverters Integrated in Algerian LV Distribution Network

The integration of solar photovoltaic (PV) systems into the low voltage distribution network (LVDN) has recently amused interest. This is due to various advantages, including low production costs, high efficiency, scalability, etc. Due to the obvious potential impact of these additional PV systems on voltage violations, penetration limits are frequently imposed. Distribution network operators must consider additional control functions that can cost-effectively organize the current and future utilization of grid-connected PV systems (GCPVs) in order to defer potential network reinforcements. Active power control Volt/Watt and reactive power control Volt/Var methods can mitigate voltage violations in such situations. This work aims to investigate the use of new PV inverters in critical PV systems, where there are large voltage violations due to high PV penetration. A real case study, with data and parameter measurements of a PV generator connected to the Algerian network, is used to validate the simulation methodology proposed to show how new PV inverters can be implemented to integrate PV systems in the LVDN. Using advanced Volt/Watt and Volt/Var functionalities.
