BiographyBroad area of research: Smart Systems
Professor Ghosh has been actively involved in research in the broad areas of
- Power systems
- Power electronics
- Control systems.
He is currently active in the research areas of
- Custom power technology
- Flexible AC transmission system
- Control of power electronic devices
- Hybrid and switching control
- Distributed generation and grid interconnection.
Main areas of research
The areas of activities include theory, computation and experimentation. The current research activities involve the study of the theoretical aspects of the implementation of FACTS and custom power devices in power transmission and distribution systems respectively. This is followed up by extensive simulation using the software packages like PSCAD/EMTDC, MATLAB, SIMULINK etc. to support the developed theory. These are further verified experimentally on laboratory prototypes at a lower voltage and current levels. Currently specifically involved in the following projects
- Performance evaluation and stability studies of multimachine power systems where multiple FACTS devices are installed. This project involves analysing the system stability using trajectory sensitivity, control design, network reduction, development of stability software in MATLAB and verification through extensive simulation studies.
- Hybrid and switching control design for the control of power electronic converters. This project investigates the system stability when power electronic converters are switched at fixed or variable frequency, as well as when they are controlled with space vector modulation.
- Design and testing of multilevel inverters. Currently simulation and implementation of 3 and 5-level flying capacitor inverters are in progress. Also the performance evaluation of cascaded transformer multilevel inverters is in progress.
- Development of custom power devices. This project involves the theory, control design and implementation of devices like DSTATCOM, DVR, UPQC in power distribution systems. This has been the area of major activity for the past few years and all these devices have been studied extensively. Current emphasis is to connect more than one device in a distribution system and study their control interactions.
- Distributed generation, grid interconnection along with hydrogen economy. These aspects will be very crucial for the future power system. Also, since these require extensive power electronics, the experience of the development FACTS and custom power technologies can be directly applied here. The major emphasis is the development of a microgrid through which remote areas can be supplied efficiently.
