Behaviour of Photovoltaic Power Plants in Low-Demand Power Systems

This paper analyzes the behavior of photovoltaic (PV) power plants in low-demand power systems, with a focus on the power system of Bosnia and Herzegovina. To achieve a realistic representation of operational conditions, meteorological data specific to the region were incorporated into the analysis using a custom Python application for data collection and visualization. Simulations were performed using the EMTP software package to evaluate system performance under normal and faulty conditions. The behavior of both distant and close PV power plants was analyzed across various scenarios, with special attention given to the effects of different types of short circuits, the most common failures in power systems. The findings provide insights into the dynamic response of PV power plants in low-demand scenarios, contributing to improved stability and fault management strategies.
