Title: Energy Access and Off-Grid System: An Opportunity to Empower a Billion Lives!

Abstract: “Affordable and Clean Energy” is the objective of UN Sustainable Development Goal 7 where all the means and ways to achieve 100% electricity to all is being worked out. Renewable energy sources such as PV, Wind energy, hydro power is considered as clean energy. Power electronics can play a key role in integrating the various renewable energy sources to the point of load. It can be achieved through scaled down converter prototypes and distributed converter prototypes. IEEE Empower a Billion Lives is a global competition aimed at fostering innovation to develop solutions to electricity access. Empower a Billion Lives unleashes innovation through the development and demonstration of new regionally relevant, holistic, scalable, and economically viable solutions by leveraging 21st-century technologies that feature exponentially declining prices and have shown rapid global adoption.

Title: Computational Modelling and Analysis of Tidal Current Turbines

Abstract: The global energy system is going through a transformation phase and renewables are replacing conventional fossil fuels based energy resources. Tidal current energy has the potential to provide a new renewable energy source to the world. Tidal current energy is a form of hydrokinetic energy extracted from the water flows in tidal channels. Such flows takes place due to the relative motion of the gravitational fields of the moon, sun and earth. Tidal energy technology has successfully gone through various development phases, with demonstration systems currently operating in relevant environments at pre-commercial scales.
In this talk, an overview will be presented on the ocean current energy and the devices for extraction of tides energy. Then a specific interest will be given to the computational modeling of tidal current turbines. Tidal Current Turbines (TCTs) often derive their design principals from wind turbine design. However, there are certain key differences that needs careful consideration. The proper understanding of device behavior is necessary to make this technology cost effective and reliable.
Different methods are used for simulation of performance parameters and wake of tidal current turbine to provides greater insight into flow-physics and unsteady loading. Although RANS CFD based numerical models can model the hydrodynamic behavior of a TCT but it has the limitation that it assumes the blades to be rigid. Numerical models capable of accounting for the Fluid Structure Interaction (FSI) and hydroelastic behavior of the turbine blade can provide a better approximation of the turbine performance and near flow fields. Some FSI studies have already been conducted to gain an insight into the performance of tidal turbine. However, more such studies are still needed to further the understanding of the design and performance of turbine
