PROJECT: Electric Vehicle Charging infrastructure with smart chargers to reduce degradation of the battery
Supervisor: Prof Dr.-Ing. Praveen Kumar
Brief Description: The rise in environmental degradation concerns has led governments and organisations worldwide to look for electrification of systems running on fossil fuels. Inspired by the benefits of electrification of the transportation sector, this work focussed on developing charging infrastructure for electric vehicles. The first work in the project developed an algorithm to reduce the cost of sampling by improvising the controllers that monitor and control the flow of power between electric vehicles and the electric grid. The second work focuses on reducing the impact of communication issues such as data loss and delay by developing an intelligent controller using an artificial neural network. The third and fourth works focus on developing smart chargers with capabilities to estimate parameters of the battery, decide the type of charging technique to fast charge and reduce battery degradations. The third and fourth work involves the use of electrochemical models of Li-ion batteries and development of hardware prototypes.

PROJECT: Design and Analysis of PQ improvement technique for three-phase SEIG in single phase operation
Supervisors: Dr. Abhishek Kumar and Dr. Ralli Sangno
Brief Description: This project aims at the power quality aspects of a 3-phase generating system (Induction Generator) for distributed generation system, emphasising the imbalances in reactive power and harmonics in the current waveform when fed on single-phase loads. A three-Φ self-excited induction generator in single-Φ operation by employing Fukami’s configuration is modelled using MATLAB/Simulink to feed single-Φ diode rectifier load. For this purpose, a general mathematical model of the system in a synchronously rotating reference frame has been used. A control scheme is developed to ensure a balanced operation and to improve the power quality of the system. For this purpose, a STATCOM based mitigation technique has been designed. The STATCOM provides the required reactive power and eliminates the unbalances in generator voltage and current and removes the system's harmonics under application of a single-Φ diode rectifier load.
