Influence of small consumption customers in the category of distribution customers

The total number of customers in EP BiH was estimated to be 150,000. Weekend houses in the supply area of EP BiH were assumed to be at least 50,000. The average monthly consumption of customers from categories c-d was 29 kWh. Daily consumption of 100,000 customers from groups c, d, and e peaked in two periods lasting two hours within a day. Analysis of customer categories c, d, and e revealed that customers c, which included garages as individual facilities or spaces within a housing/business facility, used energy during working hours, particularly from 16/17 hours. Customers d, which included common areas within a housing/business facility, used energy during specific periods, although the exact usage patterns were not specified. Customers e, which included staircases and elevators, used energy during afternoon/night hours and 7-9 hours and 15-17 hours, respectively. Customers f, which included weekend houses, used energy on Saturdays and Sundays, with peak usage on Sundays until 15-17 hours. The analysis showed that the peak power for garages, elevators, and common areas represented 6% of the peak power for the category of households obtained by the load research process done by EP BiH Team. Based on this finding, the proposal was made to eliminate customers from groups c, d, e, and f from the load research analysis, as it would not significantly change the load curve of household customers. However, it was recommended to organize load metering for individual characteristic customers from these groups in the future to obtain necessary information about their load and consider the results in future analysis if justified.
