Adaptive demand response to improve economic performance of microgrids

Recently, increased attention has been focused on the demand response (DR), especially in the smart grid environment, where bi-directional communication can be implemented between smart meters and power grid. The smart household appliances can be controlled to actively respond to the control and fre...
