Abstract

A community based energy management method which avoids energy peaks oftentimes associated with the restart of appliances after the delayed start of an appliance due to energy use restrictions is lifted by a utility company. The method includes the application of a queue model, such as a first-in, first-out model for the restart time of any delayed electrical device.
