Implementation of a demand elasticity model in the building energy management system

Abstract

Nowadays, crucial part of modern Building Automation and Control Systems (BACS) is electric energy management. An active demand side management is very important feature of a Building Energy Management Systems (BEMS) integrated within the BACS. Since demand value changes in time and depends on various events, factors and parameters, a demand elasticity model has been proposed to provide reliable information about current and expected energy demand. In this paper we propose extension of this model with respect to parameters available in the BACS, determining energy demand level. Real data from the BACS had been imported into a calculation algorithm and proposed approach has been verified in simulation. For easy implementation of the demand elasticity model in the BACS, an extension for logical interface with a new functional profile has been proposed and described. It is ready for integration within the BACS with Internet of Things paradigm.
