Optimized Energy Management in Smart Buildings with Energy Trading

In this paper¡ has been proposed the collaboration between smart buildings as a solution for improving the energy efficiency and increasing the contribution of the consumers in energy consumption management of residential buildings integrated with micro-grid. In the proposed model¡ the scheduling of power consumption in smart building and the optimal operation of distributed energy resources through molding of the exchange energy among smart buildings is presented using mixed-integer linear programming (MILP). The smart buildings are equipped with building energy management system (BEMS)¡ distributed generation¡ and energy storage system. Being considered as a small micro-grid¡ each building is able to feed parts of its own electricity demand and all thermal demand. The proposed model is applied to the two smart buildings consisting of 30 units and 90 units. The simulation results indicate that the collaboration among smart buildings will lead to the more power trade options¡ the reduction of energy consumption costs¡ the reduced received power from the grid¡ and the balance between supply and demand.
