Abstract
The liberalization of the electricity market, the transition from fossil fuels, and the ambitious goals for achieving climate neutrality strongly encourage the integration of distributed renewable energy sources. However, this shift can lead to significant challenges in maintaining power quality. Issues such as voltage fluctuations, frequency deviations, and harmonic distortions are more likely to occur, potentially compromising the stability and reliability of the power grid. The key solution to these challenges comes from a Hosting Capacity Analysis which provides a precise estimate of the maximum capacity of distributed renewable energy sources that can be integrated into a selected part of the network. In the example of an “Elektro-Kreševo“ operating unit Hosting Capacity Analysis was conducted considering technical limitations, emphasizing determining the capacity for photovoltaic power plants.
