Hosting Capacities of LV Distribution Network with Dispersed and Concentrated PV systems connection

Increased integration of photovoltaic (PV) production creates new challenges and opportunities for the Distribution System Operators (DSO). It is crucial to establish comprehensive standards for the maximum integration of PV systems without disrupting normal operations. This paper explores the hosting capacity of concentrated and dispersed PV systems connected to LV network. The aim is to determine the maximum amount of PV generation for the low-voltage network considering voltage, line loads and transformer thermal constraints. Simulations are performed on a model of real power systems in DigSilent Power Factory software. This paper encompasses a wide range of activities vital for the successful integration of PV systems into low voltage distribution network that has been converted into micro-grid. Goal was to ensure stability, security, and efficiency of the grid while exploring best possible ways of connecting new renewable energy sources.
