Abstract
The sustainable transition to a fossil-free energy system with a high penetration of energy conversion technologies based on fluctuating renewable energy resources, like wind and solar, calls for a paradigm shift in power systems. Traditionally, the systems have been designed with centrally-situated large power generation operated to meet the demand. However, to support the transition to a renewable energy system a change is suggested, where demand is adjusted to the available generated power. Moreover, this modification moves towards a bi-directional decentralized system with smaller units and multiple prosumers. The use of model predictive control in buildings is seen as a strong opportunity to minimize costs, while still meeting the comfort requirements. This control can either be centralized or decentralized by each building owner, which is the focus of this paper.
