Microgrid works as a local energy provider for domestic buildings to reduce energy expenses and gas

emissions by utilising distributed energy resources (DERs). The rapid advances in computing and communication

capabilities enable the concept smart buildings become possible. Most energy-consuming

household tasks do not need to be performed at specific times but rather within a preferred time. If these

types of tasks can be coordinated among multiple homes so that they do not all occur at the same time

yet still satisfy customers’ requirement, the energy cost and power peak demand could be reduced.
