Building Energy And Demand Response Simulation Model: Automatic Modeling And Calibration

Since the reform and opening of our country, we have gotten great development in the economic as well as people's lives. At the same time the energy consumption of building is growing rapidly. According to the statistic it accounts for about one fourth of the whole society energy consumption and is still growing. After the new century coming, the problem of lack of energy is more and more serious in China. There is not much time left for us to do research about building energy savings. With the development of computer technology, building energy simulation becomes an important method in the research of building energy savings because it is cheap, convenient, fast and unlimited. The lack of energy especially the power always occurs at peak load time. So through the demand response research, adjusting the running of buildings properly may reduce the energy consumption at peak load time and this reduction will help to resolve the energy problem. Building energy simulation and demand response research have become new research focus now. They are also the focus of this thesis.In this thesis, the author first introduced the background and the importance of this research and analyzed the shortcuts of current building energy simulation tools. Then the author introduced the building energy simulation software—EnergyPlus briefly including its characteristics, related theory and simple comparison with other famous building energy simulation tools. Likewise the basic model used in this thesis and the demand response modeling method were given as well as the automatic modeling method and process. In the following, the author introduced the model calibration method in detail, including basic calibration method, model assessment criteria and particle swarm optimization algorithm. At last, a simulation tool based on above research was developed and an example was given to illustrate the function and the validation of this tool.Through above research and software development and test, the author got the following conclusions. As the new generation building simulation software, EnergyPlus is powerful and veracious. It is reasonable to use it as the kernel of building energy simulation tool. Automatic Modeling process can make a correct model quickly. Modern optimization algorithm works well in the automatic model calibration, which can find optimization solution automatically. The building energy and demand response quick simulation tool developed by Delphi AWK and DOS works perfectly. Easy input and visual output make this tool easy to use. In addition, the report of this tool is comprehensive. The accuracy of this tool meets the requirement of Federal Energy Management Program(FEMP).
