A solar dashboard for India. A cooperative project between ICER & RBCCPS

Principal Investigator

Duration
1 December 2014 to 30 November 2016

Renewable energyis a critical component of India’s energy portfolio given the ever increasing costs and large capital investments required by fossil fuel based generation. With solar power being a key part of this, a wide range of implementations can be expected from roof-top solar implementations, through micro-grids to large scale solar generation facilities. A huge need exists to develop a comprehensive picture of the deployment, operation and output of such systems, and to couple this information with insolation, geological and climatological models to understand the optimum way to grow and manage solar power infrastrusture in India.

The long term goal of this project is to enable the construction of a data gathering capability that can be deployed at the scale necessary to collect this information and to contribute to a total pathway for solar energy deployment in the country. A key component of this pathway was the development of facilities to ensure optimal operation. The project built a scalable measuring and monitoring infrastructure for development of condition based maintenance of photovoltaic generation systems. In addition to the infrastructure, the project developed algorithms tuned to local deployment and operational practices, and to local environments to optimize the operational efficiency of deployed systems such as in rural micro-grids.

The infrastructure and algorithms were tested and validated against a 5MW photovoltaic implementation that was instrumented and operated as part of the project to provide realistic design and operating data. The system will be extended to cover the solar thermal plant at Chellikere. Subsequent to that, the system will be scaled successively to incorporate corporate and facility solar generation and solar generation facilities with the goal of scaling to a comprehensive national facility. The project also examined the feasibility of providing “micro-monitoring” down to the level of individual roof-top solar installations.


Sensor network based cyber-physical infrastructure for continuous monitoring of water distribution networks

Principal Investigator
Prof M. S. Mohan Kumar (Professor, Department of Civil Engineering)

Duration
1 May 2014 to 30 April 2016

Water distribution systems (WDS) are one of the most critical infrastructures of a nation. It serves drinking water to the millions of people in the country. An accident or damage on the same will risk the life of many people. Hence securing the water network is of utmost importance. Indian water distribution network is under tremendous pressure owing to population growth, ageing infrastructure, poor maintenance, etc. Water supply in most of the Indian cities is intermittent. These factors cause the quality of water in the system to deteriorate to unacceptable levels. Pressure surges due to intermittent water supply cause pipe bursts and leakages which again increases the possibility of contamination (like cross contamination, accidental contamination, etc.)

And this is why the concept of “Smart Water Networks” is important. Such a network is transparent and flexible to meet future challenges and carries out efficient asset management; as a whole it provides a reliable source of water to the consumer. In a smart water network, water quality and quantity data can be collected from the source to the consumer points using sensors, and is transmitted to a central data base where it can be analyzed to understand its change in its hydraulics and quality. Collecting and analyzing water network data enables better understanding of the dynamics of the system and helps in improving system operations and the control on the system. Remote detection of leaks and water losses early detection of contaminant events, real time data acquisition, data analysis, demand forecasting online modelling, energy optimization, sensor placement optimization, real time control, etc. are the key features of a smart water network.
