Residential Demand Response strategies
Permanent address of the item is
Nowadays Demand Response (DR) in Finland is market based, and such approach as controlling of domestic loads by a special type of a controller is developing. It would allow excluding of a human segment from a connection between the system operator and loads, as well as to perform automation processes in the fastest and the most efficient way. Hence, one of the possible implementations of DR is becoming direct control of domestic loads. Thus, the primary aim of this thesis is studying of DR opportunities for a conventional detached house. Another important purpose is to find ways of power consumption peaks clipping that have negative impact on a power network. It is also necessary to reveal actions for decreasing of pay - back energy consumption peaks. Finally, intention behind the paper is to provide information for future works. In this work efficiency of DR actions is measured in terms of saved energy harvested from a specific DR event. For these aims a thermodynamic model of a house and models of electrical appliances have been built. Further, various DR programs (shut off, preheating, temperature settings diversification) and strategies associated with them are probated by the means of these models. The main limitation here is preserving comfort living conditions inside the house. The results of the research method above allow to obtain necessary values of saved energy and power for different tests. Moreover, the most suitable strategies of equipment controlling have been detected, especially in minimization of pay - back power peaks point of view. Finally, utilization of such models in energy management has been determined. In conclusion the main findings of the given thesis and their meanings are presented. Furthermore, points for further application of the achieved results have been given.
