Sankar Professor, Dept. of EEE JNTUA College of Engineering Ananthapuramu, India vsankar.eee@jntua.ac.in Abstract— The Power distribution system reliability is the Evaluation of halt probability of customers power supply over a given distribution network on power system. The Distributed Generators are like wind renewable energy systems and Modern Electric Vehicles (MEV) taken into the same Distribution System and evaluate the halt of the power supply to the customers. To make reliable power supply, estimating the cost of halted power supply to the different types of customers in different possible situations is of prime concern. The power distribution network modeled in NEPLAN Software and load distribution is evaluated by giving the MEVs and wind generating stations as inputs at different nodes within the power distribution network. Estimated the customer Power Supply Halt Cost (PSHC) by using appropriate customer damage functions by using MATLAB. The aim of the work is to be analyze the PSHC of power consumers and provide reliable power supply to them.

INTRODUCTION There is a vast innovation improvement in the electric power systems which could be identified with the conventional ranges of electric power era, transmission and utilization. Of late, the clients of power turn out to be more dynamic, which can go about as both the consumers and in addition the producers of power. The PDS arranging with wind energy or MEVs having a few drawbacks like both wind era and charging/releasing power profile of MEVs dynamic however not unfaltering. Furthermore, the consumers PSHC has not considered. In General, the Electrical Vehicles are used for transportation purpose only. But in recent days Eco-friendly systems are being used in order to protect our environment by reducing the emission of carbon and hazardous gases into the air. At the same time, reducing the sound pollution is also important. Reducing the sound pollution can be done by MEVs. One more feature of MEV is, whenever power generation fails to meet the consumer demand, the electric power which is stored in MEV, return back to the grid, Charge or Discharge of the vehicle is monitored/ controlled by the owner. Whenever grid demands power, it will send the message to the MEV owners. If user wishes to give back, then DoP to the grid may occur. The MEV vehicles to the grid is well equipped having capability of bi-directional power flow, particularly there MEVs are under residential and commercial power consumers. The renewable energy sources like wind energy systems are comparatively more economical in power generation. So many countries have already proved that getting exceptional power outage while using the wind energy system effectively. But in wind power generation there is some toughness in capturing the random behavior of wind. Naturally wind having irregular property and it is hard to analyze the results. But for the effective analysis the randomness in the behavior of wind generation is also inculcate with the distribution power systems. Past Research work has been centered on wind era and MEVs charging/releasing power [9]. A hybrid learning automata framework is produced to locate the ideal disconnected control settings over an entire arranging time of a PS consolidating WP and EV request/supply power [5]. Andersson et al. [7] concentrated on the cost/advantage examination of MEVs. Some exploration is centered on client interference brought about by feeder shortcoming [6] and the vulnerability of renewable vitality era and MEVs charging/releasing profiles are excluded up to now. Both MEV Bi-directional power flow through the grid and wind power generation are having random behavior. To get the more reliable power to the consumer, these are included in this paper. There is need of power supply to be continuous to the consumers economically. There are several customer damage functions using in the evaluation of customer PSHC [1]. In the power consumer point of view, minimum power halt duration is taken as 1 minute. Load model is hourly based either MEV or renewable energy source like wind generation. The paper has been sorted out in the accompanying way: Section III portrays the strategy of inputs apply to the system.
