Abstract-Reliability assessment of distribution system, based on historical data and probabilistic methods, leads to an unreliable estimation of reliability indices since the data for the distribution components are usually inaccurate or unavailable. Fuzzy logic is an efficient method to deal with the uncertainty in reliability inputs. In this paper, the ENS index along with other commonly used indices in reliability assessment are evaluated for the distribution system using fuzzy logic. Accordingly, the influential variables on the failure rate and outage duration time of the distribution components, which are natural or human-made, are explained using proposed fuzzy membership functions. The reliability indices are calculated and compared for different cases of the system operations by simulation on the IEEE RBTS Bus 2. The results of simulation show how utilities can significantly improve the reliability of their distribution system by considering the risk of the influential variables.

“…Equation (10) demonstrates that, in addition to the expected negative and zero sequence impedance and positive sequence of voltage, a negative and zero sequence of voltage also appear due to the presence of single-phase PVs that are distributed unequally among the three phases of the network [18].…”

This paper evaluates the effect of randomly distributed, residential single-phase rooftop photovoltaic systems in the low voltage residential networks, during short-circuit faults on the overhead lines. The important parameters such as the fault current, the current sensed at the distribution transformer secondary, and the voltage profile along the feeder during the fault are examined. A sensitivity analysis is carried out in which the rating and location of the photovoltaic systems in the feeder, as well as the fault location and type, are the considered variables. Moreover, to demonstrate the effect of multiple photovoltaic systems with different ratings and penetration levels when distributed unequally among three phases of the network, a stochastic analysis is carried out. The paper summarizes the outcomes of these two analyses to provide a better understanding of the impact of single-phase rooftop photovoltaic systems on the residential feeders during shortcircuit faults.

“…The rotor efficiency of a wind turbine depends on the mechanical design of the rotor blades. Power coefficient is used to calculate the amount of power captured by turbine that was available in the wind On the other hands, the generator efficiency depends mostly on the electrical design of the generator [19].…”

A small scale vertical axis wind turbine (VAWT) with axial flux permanent magnet (AFPM) generator has been designed and magnetic levitation method is used to increase the efficiency of this type of wind turbine [1]. Magnetic levitation is inserted by using rare earth permanent magnets, the repelling force of magnets are used to suspend the rotating part of both turbine and generator. Moreover, design of simple generator which can easily drive without geared mechanism, lessen cost and the complexity of the system by reducing the quantity of driving components. Three phase output is obtained from designed generator which is converted into direct current through three-phase rectifier to charge the batteries. The performance of proposed prototype is also tested experimentally. The turbine performs as predicted by the design process.
