Scope and Objectives

The overarching goal of the project is to provide technology solutions for enabling residential, commercial and industrial loads to participate in energy efficiency and demand response programs. A key idea behind the solution development is to collect meaningful information using basic sensing technology and process the same on suitable platforms to control end-use consumption. Specifically, it entails designing of low cost, energy efficient sensor nodes and data processing software platforms as well as devising of control mechanisms for demand management applications. Given that commercial building constitute a third of the electricity demand, and roughly half of commercial load can be typically attributed to air conditioning systems, the project will extensively focus on managing the air conditioning load. In particular, live test beds would be created on IIT Bombay campus for testing and validating the proposed solutions. Furthermore, a simulator capable of emulating an air conditioning load would be designed to investigate how different control strategies impact the load consumption. This would help ascertain the best way to participate in energy efficiency and/or demand response programs.

Deliverables

1. low cost and energy efficient sensor nodes for demand management applications
2. software platforms for processing and analyzing the sensor data
3. interactive web interfaces for collecting as well as displaying information
4. control algorithms for demand management applications
5. actuators for controlling air conditioners, fans and lights
6. live testbeds on IITB campus generating data sets for energy optimization
7. air conditioning load simulator
8. sensor data sets.

Scientific Output

The design methodology adopted in this project embraces the paradigm of plug-and-play architecture so that solutions are modular, expandable, and easy to deploy. The design choices made by the team have lead to highly efficient sensor and actuator nodes. The data sets generated during the course of this project can be used extensively for various studies such as those focused on energy optimization/control as well as those pertaining to study of energy consumption patterns. The testbeds created on the campus would provide live environments to validate the proposed solutions. The project team will publish papers and/or reports documenting the solution development as well as testing.

Societal benefit and impact anticipated

Lower energy demand is desirable since it reducing the generation demand. While on the other hand, enabling demand response has other benefits in terms of coinciding

Next steps

The sensor nodes will be further honed allow for USB-powered charging and on- air programming for easy maintenance. Control strategies for appliance control using laws of thermodynamics as well as sensor data will be developed. Sensors, actuators and control mechanisms will be extensively field tested and validated.
