Advanced evaluation model of expected energy not supplied in distribution power network

Expected energy not supplied (EENS), caused by faults and maintenance activities, is overestimated with classical approach. There are important direct financial losses (power system's company, industry sector, financial institutions) and indirect losses (education, culture, life standard) due to non voltage periods. System controlling and data acquisition (SCADA), integrated in modern distribution power system, improves possibilities in data analyzing and prediction of the EENS in more exact and efficient way. Power demand and energy grow up immediately after non voltage period, for several analyzed cases (less than 1 hour) are twice greater then usually (power memory effect), so the EENS during the non voltage periods are even more then 50% less.
