Item Electric vehicle powertrain design with battery swapping and vehicle to grid implementation.(2021-03-31) Adegbohun, Feyijimi R., 1995-; Jouanne, Annette von.; Lee, Kwang Y.Described in this work are methodologies for the design and development of electric vehicle (EV) powertrains through modeling, simulation and validation on a real-world systems, with detailed analysis of results. A system for swapping, storing and managing EV batteries, including a Deep Neural Network (DNN) based state of health estimation model is developed and analyzed. The system is designed to enable advanced interface with the electric grid and address challenges in the adoption of EVs which include : Cost, range anxiety, charging time and charging infrastructure, battery state of health, and impacts of vehicle to grid (V2G) operations. The EV battery swapping system (BSS) consists of the EV powertrain equipped with swapping capability, modular swappable battery packs, battery storage apparatus, bidirectional charging system, battery and charge management system, and battery swapping equipment. This system provides a cost-effective way of adopting electrification, reducing strain on the electricity grid during peak periods and extending the life of EV batteries.Item Real-time modeling, simulation and analysis of a grid connected PV system with hardware-in-loop protection.(2017-03-29) Adegbohun, Feyijimi R., 1995-; Lee, Kwang Y.Renewable energy resources have become an integral part of the power and energy industry in the world today. Photovoltaic (PV) systems are one of the most common and established forms of renewable energy technologies. With the increased installation of PV systems both on a small and large scale, it is high critical that the impacts and operations of PV systems are accurately modeled, simulated and studied. This thesis focuses on introducing a real-time simulation approach to the study of renewable energy resources that are grid connected. PV systems are the main focus of this thesis, highlighting some of the technical challenges involved in the integration of PV to the main power grid and presenting technical solutions that mitigates some of these challenges. The real-time simulation environment presented in this thesis is the Real Time Digital Simulator (RTDS). Furthermore, the model is interfaced with protection relay testing equipment to simulate hardware-in-the-loop testing.
