THE PRIVATE ENERGY USER CHALLENGEGovernments and energy companies are currently developing alternative electricity smart grid solutions to address energy independencies, reliability and issues of sustainability (Massoud and Wollenberg 2005, Gellings 2009, Lin, Yang and Shyua 2013. These developments will lead to a disruption of the continuous evolution of energy use practices both in private households and in energy production companies (Farhangi 2010, Lin, Yang andShyua 2013). The Danish government has determined that by 2050 Denmark will be independent of fossil fuels and the way to achieve this goal is to base the energy system on electricity from mainly wind turbines. This means that a smart grid system in this context will not only optimize the distribution of energy between the energy company and the user, but also the smart grid must integrate the unstable character of electricity produced by wind turbines. Energy users will have to cooperate with the system and use electricity when it is available -when the wind blows. A future electricity smart grid is based on an intelligent bidirectional communication between a range of different energy producing units and energy demand units -including our Danish energy company and the private energy end users
