Abstract
This paper reports an experimental implementation of a flexible prosumer that adapts its behavior according to occupants’ objectives and system operator’s request. Model predictive control is incorporated into an existing building energy management system such that the energy management system can achieve user-defined objectives while quantifying energetic flexibility to support a stable and efficient system operation. Context-awareness is demonstrated through a series of experiments with energy efficiency, cost reduction, and carbon footprint reduction as occupants’ objectives. Besides, the flexibility of the prosumer is quantified in real-time and communicated to system operators. The results show occupants’ comfort and preference can be sufficiently guaranteed. Moreover, the flexibility quantification shows that the energy management system has considerable impacts on the levels of available flexibility.

Summary
Digitalization enables building energy management systems to operate in an occupant-centric manner [1]. Objectives such as user comfort, cost, energy efficiency, selfconsumption, and flexibility can be included or combined according to the occupants’ needs [2]. Buildings have the potential to provide the much needed energetic flexibility to support the operation of the future distribution system [3]. The results show that an implemented control strategy has notable impacts on the level of available flexibility. The remainder of the paper is organized as follows: Section 2 presents the overall methodology of implementing the context-aware and flexible prosumer. The experimental results related to control of Space Heating (SH) and Domestic Hot Water (DHW)
