A simple vocabulary for semi-decentralised management of energy demand in households

This paper presents a demand-side management approach for electrical energy in households which can utilise locally available renewable energy resources like wind and photovoltaics. The concept which was developed gave rise to two kinds of vocabularies: The first one is a classification of household appliances which bundles appliances having similar interfaces, user interaction and demand side management opportunities. In particular, the local control actions are the same for each appliance class. The second vocabulary is used for the communication between a central energy management unit and the appliances. Simple control signals are not sufficient here, since the energy management unit might need a lot of information about the specifics of the appliance and its current state of service. Therefore the EMU issues cost profiles for certain future time periods to be taken into account for the local control. We also give two examples on how these cost profiles are used in the case of schedulable and thermal services for local control planning.*
