 abstract={In recent years, the increase in the share of unstable energy sources classified as renewable energy sources, wind turbines, and photovoltaic installations in the national (Polish) energy mix has led to the emergence of new challenges. These challenges include what to do with excess energy production in the face of low prices and low storage capacities. The solution used in 2023 and 2024 was the forced shutdown of sources on the scale of the national power system. A gap was noticed in the methodology for assessing which installations (wind turbines or photovoltaics) should be shut down on the scale of one power connection in the so-called cable pooling cooperation formula. In this respect, a decision-making methodology was developed for shutting down generating capacity based on operating costs. Scenarios for the installed capacity of individual sources were defined: photovoltaic installations and wind turbines. Then, an analysis of scenarios of different capacities of individual farms was performed compared to one side of the power connection. It was proven that in most cases of cooperation between photovoltaic farms and wind farms, wind farms should be shut down first in the event of exceeding the capacity from the point of view of one owner for one connection for these farms. The results also voiced the discussion on compensation for installation shutdowns on the scale of the entire power system in Poland. Nevertheless, the estimates in this area have a wide area for in-depth analyses for individual sources, taking into account various conditions, e.g., age of devices, local conditions.},
