 The rapid growth of renewable energy sources has created new challenges and difficulties in maintaining reliable and sustainable electricity supply. These include the need to balance the energy system, analyze voltage stability, overcome the consequences of increased short circuit currents, increased transmission capacity of the system, and accurately predict future load and consumption levels. To address these issues, this paper examined the impact of connecting photovoltaic plants to a microgrid and analyzed the effects on voltage stability. The study was conducted using the Netplan software environment and data on the type and cross-section of the conductor of the studied power line. The results showed that the number of loads connected to the microgrid must be limited to avoid an imbalance in the network. Additionally, the optimal operating mode of the system was identified by evaluating the permissible limits for network stability.
