A novel method for demand response by air-conditioning systems in a microgrid with considering wind power generation variation

The role of demand response becomes more decisive when there is a large penetration of intermittent renewable energy resources into the electrical grid. One of the demand response programs is the direct load control methods. With the current rapid growth of computing resources and communication systems, the ability to extend the direct load control systems now exists. Demand response systems now have the ability to not only engage commercial and industrial customers, but also the individual residential customers. Moreover integration of intermittent electrical power resources to power system, such as wind power, creates new concerns for operation engineers. One way to deal with this uncertainty is demand response programs. Air-conditioning system is one of the high consumption end use loads. This paper presents a novel method for direct controlling of residential air-conditioning systems with regards to the welfare level of the residents. In this method the amount of energy consumption of these loads has been coupled with wind power generation rate, by attention to the outside temperature. Then this method has been implemented for air-conditioning systems of a Microgrid, consists of dispatchable and non-dispatchable power resources and loads. The simulation results of this proposed controlling method have been shown in the short term operation planning of a Microgrid.
