Title- How will India scale its Electric Vehicles


Over 83% of India’s vehicles are two and three-wheelers (including small goods vehicles), 3% are buses and trucks, 12% are economy cars, costing less than ₹1 million and only 2% are premium cars with a cost over ₹1 million. The world’s program of electrification of its vehicles is focused on this 2% premium cars. India’s vehicle-electrification program have to be different, in tune with it affordability. India would have to design the most energy-efficient vehicles to bring the cost down. It has to come with a different EV charging / swapping infrastructure, as compared to that in the West. Its focus has to be first on 2-wheelers and 3-wheelers, small cars and buses. Its batteries have to be smaller. Charging have to take into account India’s hot temperature. It has to have the most energy-efficient motors. Industry and Academia have been working in India to drive India’s EV program without any Government subsidy and has taken early steps. Scale up will become visible within two years. The talk will elaborate on approach and technological challenges.

Abstract :

The energy paradigms in many countries (e.g., Germany and Denmark) have experienced a significant change from fossil-based resources to clean renewables (e.g., wind turbines and photovoltaics) in the past few decades. The scenario of highly penetrated renewables is going to be further enhanced– Denmark expects to be 100 percent fossil-free by 2050. Consequently, it is required that the production, distribution and use of the energy should be as technologically efficient as possible and incentives to save energy at the end-user should also be strengthened. In order to realize the transition smoothly and effectively, energy conversion systems, currently based on power electronics technology, will again play an essential role in this energy paradigm shift. Using highly efficient power electronics in power generation, power transmission/distribution and end-user application, together with advanced control solutions, can pave the way for renewable energies. In light of this, some of the most emerging renewable energies — , e.g., wind energy and photovoltaic, which by means of power electronics are changing character as a major part in the
electricity generation —, are explored in this paper. Issues like technology development, implementation, power converter technologies, control of the systems, and synchronization are addressed. Special focuses are paid on the future trends in power electronics for those systems like how to lower the cost of energy and to develop emerging power devices and better reliability

  Title – Microgrids


A microgrid is defined as an aggregation of electrical loads and generation. To the utility, a microgrid is an electrical load that can be controlled in magnitude. This load could be constant, or could increase at night when electricity is cheaper, or could be held at zero during times of system stress. A microgrid can improve the reliability of the power supply, possibly at a lower cost. The technology can be effectively used for combined heat and power applications. It reduces the transmission power loss. It reduces the environmental impacts. It is also well suited for off-grid, remote area applications.
The microgrid concept has been around for over a decade now. It has matured from this to demonstration and implementation phases though research and development activities. This talk will start with the basic concepts of both ac and dc microgrids. This will be followed by the operation and control challenges of microgrids. Finally the usefulness of microgrids under the smart grid umbrella will be outlined.

Arindam Ghosh is a Professor (Research Academic) at Curtin University. Prior to joining Curtin University in November 2013, he was a Research Capacity Building Professor in Power Engineering at Queensland University of Technology, Brisbane, where he joined in May 2006.

Title –  Predictive Control – When to use and when not?


Switching losses contribute the major portion to the total losses in medium voltage drives. Operation at extremely low switching frequency is therefore mandatory. Low harmonic current distortion can be nevertheless achieved when predictive current control is applied.
The method is presently attracting the interest of many researchers. Even specific conferences are being organized on this novel topic. The predictive algorithm directly generates the firing pulses of the inverter, thus eliminating a pulsewidth modulator. A preset magnitude of the current error is maintained, defined as the difference between the current reference and the actual current space vector. The inverter gate pulses are generated while maximizing the time differences between any two switching instants. This minimizes the switching frequency, and thus the switching losses. The decision is based on predicting the currrent trajecories of all possible switching states. The method reduces both current distortion and switching losses. It increases the utilization of the inverter hardware.

Joachim Holtz graduated in 1967 and received the Ph.D. degree in 1969 from the Technical University Braunschweig, Germany.
In 1969 he became Associate Professor and, and in 1971 Full Professor and Head of the Control Engineering Laboratory, Indian Institute of Technology in Madras, India.
