Estimation of Electrical Energy Not Supplied in Reliability Analysis of Distribution Networks

There are many aspects about the energy not supplied (ENS) price, about estimation of the economies losses and the social economic benefit losses in the different kinds of human activity, education and life or about similar estimation in suppliers money losses due to not charged ENS. Detailed technical analyzes of some real power system faults, real demands and real deliveries are described in this paper. The ENS quantity evaluation during real power line's faults is given here. Power supplier aspect of the ENS evaluation is presented in the paper. Fault period without voltage of the day is compared with the same time period of the next or previous day. The values of ENS calculated until now have been overestimated due to magnified initial power demand neglects. The real value of ENS is evaluated by integrating function power (or electric current) in depends on time for each day (two consecutive days).
