Incorporating dynamic building load model into interconnected power systems

A driving force behind improving the information embedded power system is the ever growing need to enhance the controllability of electrical demand. The smart grid initiative approaches this problem by enhancing the communication between power system components. Bi-directional communication and increased data acquisition/transmission speeds help to portray system dynamics as was not widely available in the past. With enhanced metering/actuating infrastructures building dynamics can be incorporated into the grid with an appropriate dynamic model. The presented work proposes to utilize a dynamic building load model to integrate a building and/or a group of buildings to the electric grid and thereby evaluate its dynamic performance. The model leverages the electro thermal coupling of the building and thereby also evaluates the demand response capability of the building. This work further enhances the scope of the “smart building” classification by providing a simple tool for a network operator or planner. The model can be used to investigate the dynamic behavior of grid connected buildings under load variations or demand response actions.
