Abstract

Objectives: In this paper a comprehensive analysis of DG is done under initial configuration (base case) as well as with the feeder reconfigured environment in order to minimize the losses and to enhance voltage stability index. Methods/Analysis: In today’s trend delivery of power to customers have become a major issue in the field of power systems, one as such solution to this issue is usage of small units named as Distributed Generators (DG) entered the area of distribution systems. Findings: With the involvement of DG’s, a given system can achieve an improvement in terms of reliability, stability and reduction of losses. It just not only by using DG alone will solve the issue, but also mainly we have to focus on its location, size and the type which has to be used. Application /Improvement: For this analysis a standard IEEE 33-bus and 69-bus test distribution system is taken under nominal load consideration and the results are tabulated.

Abstract

Objectives: In Modern world power production and its efficient usage defines the development of the country. In distribution system of an electrical network due to the influence of loads, voltage profile and losses are to be focussed a lot. In order to avoid the maximum losses and to maintain the voltage profile usage of Distribution Generator (DG) plays a major role in the network. Statistical Analysis: Since we have to use an appropriate place and size of DG, a measuring technique based with index through which optimal size and place can be identified and is implemented in the work. Findings: This Paper focuses on reducing power losses by accurately giving the location and size of DG based on two indices (a) Voltage Deviation Index (VDI) (b) Voltage Stability Index (VSI). Results such as power losses, location, size and cost of DG are obtained for both initial configuration and Feeder reconfigured state for IEEE 33 and 69 bus systems were listed. Applications: These analysis help us in installation of Different types of DG to present network where demand side management has to be followed.

Abstract

This paper analyses the essential need for EVs in Indian transport, need for advanced charging infrastructure and technoeconomic comparative analysis of EVs and ICE engine vehicle. India is depending on oil imports largely for the energy needs. The share of oil imported by India was 57% at 1957, and it’ll be 97% for 2020. The escalating price of oil poses a severe problem in Indian energy segment in future. An emission from the transport sector is the key source of air pollution next to power sector in India. 13/ 20 cities in the world with highest air pollution are positioned in India. Transport and power sector have a significant effect in worsening air quality. As for these reasons the exploration of a different kind of transportation is required. Electric Vehicles (EV) are proving to be an absolutely new way to store and consume mass amounts of energy from the power grid. Battery Electric Vehicles (EV) and Plug-in Hybrid-Electric Vehicle (PHEV) offers beneficial rewards compared to the conventional ICE vehicle. Power generation from renewable sources, transmission, distribution, and allocation of energy and energy mix are developed with improved efficiency and consistency. A prearranged analysis is done for the business-related scopes of electric vehicles Indian energy sector. Data aggregator provides supplementary grid services as well as controls the electric vehicles charging.
