From Load Forecasting to Demand Response - A Web of Things Use Case

6,177 views

Published on

This paper provides a Web of Things use case from a personalized load forecasting service to a gami ed demand response program. Combining real-world measuring applications with web-based applications opens new opportunities to the smart grid. For this purpose, we propose a Web of Things framework for a novel load forecasting process at the appliance level. Firstly, we illustrate the concept design of the Web of Things framework consisting of the sensing infrastructure,
the activity recognition and the load forecasting modules.
Secondly, we show how we guarantee the modularity and flexibility for implementing all the three modules in a web-
based manner. On top of our infrastructure, we propose an
extended Web of Things use case by integrating our load
forecasting approach into a demand response concept.
