This paper investigates PHEVs effect on a distributed network while they charge in charging stations. In this paper, voltage profile and power factor improvement are made in the presence of PHEV. PHEV Charge modeling parameters such as battery capacity, PHEV daily traveled distance and PHEV entrance time to charging stations all are probabilistic. Thus, a(More)
Fault diagnosis is a vital discussion in power systems restoration. Recently, much research endeavors have been done for fault section diagnosis of power systems by using several techniques, such as rule-based expert system, logic-based expert system, fuzzy relation based expert system, neural network, optimization techniques based approach, etc. They(More)
Load shedding is the latest and most expensive operation action in order to prevent the loss of voltage and frequency of electricity networks. In this paper LS (load shedding) is occurred by means of four-step frequency relays and five-step frequency and voltage relays which consider the importance of loads and their priority.
