| Abstract |
The electric utility industry is faced with the growing challenge of providing a stable supply of power to meet the public’s demand, while also integrating rapid growth in distributed variable renewable generation. Traditional means of balancing short- and long-term supply and demand imbalance will be costly. Alternative approaches to using flexible loads in buildings are needed to mitigate the imbalance at a lower cost. In this paper, a agent-based distributed control strategy is proposed for commercial buildings to coordinate the electricity consumption of air handling units with variable air volume, chiller system, and lighting systems. Based on the market-based control, the electricity consumption is adjusted by changing temperature set-points and dimming levels in response to the market equilibrium price. The proposed strategy was tested and validated in a simulation environment. The results demonstrate the agent based-distributed control strategy managed the controllable loads in the building to maintain the electricity consumption at the desired level without significant impact on occupants’ comfort. Overall, the results demonstrate that the ILC allows coordination of the controllable loads and provides energy consumption savings. |
