The Application of Global Forecast Function in the Fower Fystem Load Forecasting Software Sevelopment

摘要

First of all, this paper analyzes the calculation process of the load forecast of power system, and puts forward a new ideas of varieties of load forecasting method according to the classification on this basis, this paper will establish a global predictive function corresponding to different kinds of load forecasting methods, and designed the software on the load forecasting on the basis of such function. This paper describes the programming ideas of using the global predictive function to conduct the single forecast method and combined forecast, which demonstrates its advantages. Finally this paper has introduced the realization of global predictive function in Visual Basic language in programming, and the corresponding interface-building and use method. Actual use shows that, the use of global predictive function can significantly reduce the program size, add flexibility in the load forecasting software, which improves the scalability as well as the extensibility of the program.
