Renewable Energy Technology
Renewable energy integration to electric power grid is a challenge even in developed countries as the intermittency and variability of the energy sources like solar radiation and wind speed affect the essential power balance on the grid, if a large share of the demand is required to be met from renewable resources. In order to address research in this domain, the Renewable Energy Technology (RET) Lab was established. RET laboratory developed through assistance from C-WET (presently, NIWE), MNRE and DST, Government of India, equipped with hard and soft experiment systems and real field data collection systems, provides active training support to the graduate and post graduate programme. Collaborations with global academic and industrial establishments too help in imparting quality research in the lab.
Wind and solar power generation are geographically distributed and such power plants are to be connected to electric distribution network in many places. These are called micro grids. The Amrita solution involves operation of wind-solar microgrid also integrated with energy storage systems like battery and pumped hydro. A technology has been developed to automatically decide in real time to charge or discharge these storage systems in a dynamic fashion as and when required so that the power balance on the grid is always ensured – that is DEMS.
