Item Impact Analysis of Electric Vehicle Charging Station on Bharatpur-2 Feeder(I.O.E. Pulchowk Campus, 2023-10) Paudel, DibyashoriThe rapid proliferation of Electric Vehicles (EVs) in recent years has brought about significant advancements in sustainable transportation. However, this surge in EV adoption has raised pertinent concerns regarding the potential consequences on power distribution networks. This thesis investigates the multifaceted influence of EV charging stations on the Bharatpur-2 feeder, a representative segment of the electrical grid. The research entails a comprehensive analysis that encompasses load profile characterization, voltage stability assessment, power quality evaluation, and an exploration of the dynamic relationship between feeder load and voltage levels. The findings from load profile analysis unveils temporal patterns and peak demand periods, aiding in grid management and capacity planning. The voltage stability assessment elucidates potential challenges arising from EV charging and offers solutions to mitigate voltage fluctuations. Furthermore, the power quality analysis sheds light on the impact of EV charging on the grid's overall quality and suggests measures for enhancement. The correlation between feeder load and voltage dynamics offers valuable insights into grid resilience and performance optimization strategies. Finally, the simulation results, including THD and power loss calculations, provide quantifiable data for decision-makers to formulate effective strategies for grid modernization and sustainable transportation integration.Item “Optimal Placement of Charging Station in Om Distribution Feeder of New Chabahil Substation Considering Dynamic Nature of Electric Vehicle Load”(I.O.E. Pulchowk Campus, 2023-12) Sah, NandkishorGlobally, the main goal of environmentalist is to reduce the problem of global warming and climate change whose one of the major sources is the existing fossil dependent transportation system, has forced many nations to implement pollution free battery-operated electric vehicle (EV) system which requires electrically operated charging station (CS). Due to this, the number of charging station integrated in the existing distribution system is increasing day by day and the increase in number is further motivated by the research being carried out for development of enhanced battery with cost optimization and subsidies provided by the Government body which is of big concern for the existing electrical distribution systemItem Optimal Placement of EV Charging Station with Randomly Distributed PV System in Bishnumati Distribution Feeder Kathmandu, Nepal(I.O.E. Pulchowk Campus, 2023-10) Paudel, SumanThis thesis presents the optimal placement of EV charging stations with randomly distributed PV system. MATLAB software is used to analyze the load flow of distribution network using sweep algorithm. The Bishnumati feeder of Balaju DCS is used under analysis and IEE 33 bus system used for theoretical part for the load flow and EV stations. The 372 kW (mix of 60 kW and 42 kW) charging stations are considered and it is evaluated that the system loss increases and voltage regulation is found poor upto 0.732 pu at distribution secondary side voltage. This shows that EV charging capacity does not fulfilled by existing distribution network and transformer. The randomly distributed rooftop solar PV system is considered in this system as distributed generation and that allows the power to flow at day time. Genetic algorithm is used for the EV charging station location and size of PV. The total 1381.2 kW of PV system is used that improves the voltage to 0.84 pu. The system loss also decreases by using PV system and is reduced from 412.55 kW to 279.15 kW. The financial analysis shows the positive NPV and payback period of 12 years.
