A New Method to Solve Large-Scale Building Energy Management for Energy Saving

摘要

Building energy saving has attracted more and more attention around the world recently. However, there are many challenges and difficulties in optimization for building energy saving due to a large amount of rooms in the buildings. So in this paper, we provide a method to manage the building energy systems for energy saving. In particularly, the proposed method is effective that can be applied to the large-scale buildings. We make the following major contributions. First, an iterative and decentralized solution method is developed. Based on this framework, the optimization problem of building energy management is divided into three sub-optimization problems. This method iteratively solves the three sub-problems to obtain the solution of the building energy management problem. Second, the three sub-problems are converted into mixed integer programming problems, respectively, and they can be solved using CPLEX. Numerical examples are used to demonstrate the performance of the method.
