DC-DC converters with high voltage step-up ratio are having increasing demand because of its applications in photovoltaic (PV) power generation systems, fuel cell based energy conversion systems, UPS, etc. Conventional boost or buck-boost converter with high duty ratio can be used for such application. However, in practical implementation, the extreme high duty ratio operation may result in serious reverse-recovery problem, low efficiency and EMI problem. My main motive is to design new converter topologies in order to obtain the higher boost with lower duty ratio. The other objectives include minimization of input current ripple, reduce the loss associated with the components and design of controllers for the high gain DC-DC converters.

(Power Electronics), VNR VJIET, Hyderabad, India Assistant Professor, Dept. of EEE, National Institute of Technology Tiruchirapalli, India. |
The rapid growth of integration of renewable energy sources and non-linear loads injects harmonics and causes disturbance in the existing power system. Moreover, the deregulated electricity market allows customers the flexibility to choose the supplier and hence it is essential to maintain the quality of supply. The continuous power quality monitoring helps in understanding the characteristics of the disturbances occurring in the system and identify their major causes. My research focuses on continuous monitoring, analysis and automatic detection of power quality disturbances using adaptive signal processing and artificial intelligent techniques. The other objective includes DSP-based hardware realization of the fast adaptive techniques for real-time power quality assessment.

(Advanced Power Systems), UCE, JNTU Kakinada B. Tech. (Electrical and Electronics Engineering), GMRIT, Rajam Assistant Professor, Indian Institute of Technology Guwahati, Guwahati, India |
Micro grids are emerging as one of the promising solutions to integrate various types of distributed renewable energy sources such as solar, wind, fuel cells and small hydro etc. with the utility grid. A majority of DG sources are integrated into the microgrid through inverters. The growing penetration levels of inductive, constant power, rectifier interfaced active and dynamic induction motor loads can cause instability of an islanded inverter based microgrid. My research focuses on designing optimal decentralized, optimal centralized, WAMS based centralized and hierarchical controller to stabilize the islanded microgrid under various load configurations and load current step disturbances.

My Ph.D. research work was focused on assessment and minimization of impacts that will be caused by the charging load of electric vehicle (EV) aggregation on the power grid. EV aggregation also have the potential to function as a widely dispersed flexible energy resource for controlled G2V (Grid-to-Vehicle) and V2G (Vehicle-to-Grid) power transfer. The exploitation of this trait of the EVs for catering the grid ancillary services under the smart grid framework also forms the subject of my thesis research work. In summary, my Ph.D. thesis work presents the charging/discharging impacts and introduces grid assistance models through G2V and V2G, exploring the technical and operational challenges in integrating this storage, a movable and changeable of its kind, with the power system.

Tech. (Power Systems), SRM University, Tamil Nadu, India B. Tech. (Electrical Engineering), Pondicherry University, Puducherry, India |
Synchronized phasor measurements provide a real-time measurement of electrical quantities from across the power system. A synchrophasor is a sophisticated monitoring device that can measure the instantaneous voltage, current and frequency at specific locations on the grid. This gives operators a near-real-time picture of what is happening on the system, and allows them to make decisions to prevent power outages. Applications include wide-area control, system model validation, determining stability margins, maximizing stable system loading, islanding detection, system-wide disturbance recording, and visualization of dynamic system response. The basic system building blocks are GPS satellite-synchronized clocks, Phasor Measurement Unit (PMU), a Phasor Data Concentrator (PDC), communication equipment, and visualization software. My PhD dissertation work mainly focuses on the utilization of phasor measurements and thereby developing subsequent techniques for enhanced monitoring and assessment of power systems. Thus, my thesis includes the development of appropriate and novel framework for monitoring and assessing the static (SSA) and transient (TSA) security of power systems using these synchronized measurements obtained from PMUs optimally placed in the system. We have tested our approach on various test systems IEEE 14-bus and IEEE 30-bus systems and on a practical Indian 246 bus network. Studies demonstrated the effectiveness of our approach in enhancing the security assessment.

Phasor Measurement Units (PMU) are power system devices that provide synchronized measurements of real-time phasors of voltages and currents. But due to the high installation costs, it is uneconomical and infeasible to place them at all the buses. My research work focuses on obtaining the optimal locations of PMUs with improved measurement redundancy for complete power system observability. Other objectives includes investigation of how synchronised phasor measurements can be used for detecting post contingency problems in real time operations and developing a methodology for real time wide area security assessment for PMU measurements.
