An Energy Ontology Focusing on Demand Side Management in Smart Homes

Abstract

By increasing the share of renewable energy sources, the volatility of available energy is rising. More and more fluctuating power generation by solar power plants and wind turbines has to be integrated into the power grid. Demand side management (DSM) represents one possible solution to achieve this goal by including energy production and energy consumption simultaneously. In this paper, we especially focus on the field of electric energy in smart homes. Considering the implementation of different DSM devices, an ontology-based approach can serve as a conceptual foundation for a necessary knowledge base. We propose an advanced energy ontology for smart homes, integrating important aspects for a successful DSM. We describe how power producers, storages and consumers are represented in our ontology. Finally, we show the scenario-based utilization of our approach.

Towards an Open Ontology for Renewable Resource Management in Smart Self-Sustainable Human Settlements

“…Load shifting is implemented within the SSSHS framework [Tomičić and Schatten, 2016] as one of the key mechanisms in maintaining the self-sustainability property. Demand side management represents a broader term and is in the focus of research of authors in [Naser et al, 2016]. Authors have developed an ontology in the domain of energy management in a smart home called DeSMaHo (the term deduced from "demand side management and smart home"), with a special focus on the demand side management.…”

“…The DeSMaHo ontology [Naser et al, 2016] covers the subject of demand side management, being one of the relevant mechanisms for the self-sustainable resource management, and is directly applicable within the "SelfSustainabilityMechanism" class hierarchy of the SSSHS Ontology. The object property "hasLoadShifting" can be directly imported with its values ("NotShiftable", "ProgramDependentlyShiftable", "AutomaticallyShiftable") to the existing SSSHS mechanisms.…”

“…The object property "hasLoadShifting" can be directly imported with its values ("NotShiftable", "ProgramDependentlyShiftable", "AutomaticallyShiftable") to the existing SSSHS mechanisms. However, being not publicly available to the best of authors knowledge, directly importing the partial DeSMaHo ontology into the SSSHS ontology is at this point not possible, so only manual entries, according to descriptions published in the paper [Naser et al, 2016] could be implemented. Within the hierarchy of the "WindTurbineTechnology" class, the ontology of wind energy systems [Küçük and Arslan, 2014] is practically compatible and complementary.…”
