The Design And Implementation Of A Region Electricity Consumption Forecast And Decision Support System Base On UML

With the development of national economy, the electricity industry has been greatly improved. Meanwhile, the problem on the rational use of energy has become increasingly prominent, which is aimed to achieve the coordination between the power supply and consumption. Electricity consumption forecast becomes a key issue in this problem. How to forecast the electricity consumption is a hot topic of the related field in recent years.Electricity consumption forecast is a kind of mathematic modeling study, which is based on mathematics statistics method. In order to identify its regular pattern and to obtain impact factors, the historical data of electricity consumption should be analyzed. Then, the internal pattern can be simulated and deduced through the use of modern simulation and computer technology. The factors of low real-time and low precision had been plaguing the power company's decision-makers. To improve the precision of electricity consumption forecast and provide support to decision-makers, this paper develops a convenient and efficient electricity consumption forecasting decision support system.According to the practical scenario, C/S mode is applied to realize the regional electricity consumption forecast system. In order to solve various types of data problems in the system, huge data import function based on Excel is developed. For the purpose of system development, many predict models are also developed to achieve accurate forecasting.Chapter 1 presents the development background and research significance of the regional electricity demand forecasting system. Many existing related works are discussed in this chapter. The content framework and section arrangement are also presented.Chapter 2 discusses the background technologies, which would be conducted this research, such as .NET framework, relationship database and Unified Modeling Language.In chapter 3 the system modeling, requirement analysis and data base design are introduced. According to the software development process, this paper also proposes the development process of the region electricity consumption forecasting decision system.Chapter 4 gives the architecture and modules division of the region electricity consumption forecasting decision system. After confirming the system model, the forecast method is added to system modules for completing the main features of the system.The last chapter summarizes the work and some new questions which are related to the forecasting decision support system. The futures of work are also proposed.
