Fairness quantification of congestion management measures in distribution systems based on customer impacts

The global energy transition poses major challenges to the electrical distribution grid. The increasing number of high-consumption appliances, such as heat pumps and battery electric vehicles, raises the risk of congestion, making effective congestion management necessary. As congestion management measures can lead to undesired comfort losses or financial implications, a fair design is crucial. This paper presents a methodology for systematic evaluation of fairness by considering customer impacts, tailored to direct congestion management methods. For this, different customer impacts are made comparable by assigning monetary values to them, and distributional fairness is evaluated using the Gini Coefficient. To enable comparison of different congestion management methods, a reasonability indicator is introduced, additionally considering the overall extent of impacts. The results demonstrate the utility of the methodology for evaluating the fairness of different congestion management methods.
