Load Forecast Of Yiwu Power System

As the basis of electric network planning, load forecast is very important work in grid research. Load forecasting is according to the operation characteristics, system capacity, natural conditions and social influence and so on, In certain conditions, determine the load data of a specific point in the future. Load forecasting of power system for the importance of people have been recognized. This paper has conducted in-depth analysis and summary on the method of load forecast, and innovative ideas to Yiwu grid load forecasting.This paper systematically elaborate the work of load forecast in power system, introduce the last load forecast research situation both inland and oversea, have good mastery of most newly emerged information and knowledge in this field. And puts forward the innovative use of weighted comprehensive prediction method in the load forecasting idea. According to the actual situation of Yiwu power grid, select the Logistic model method, electricity elasticity coefficient method and gray model method of three methods, detailed introduces the basic concept, each method generating method, model building theories, which lay a theoretical foundation for the further development of load forecasting. The use of weighted comprehensive prediction method this paper creatively carried out the Yiwu power grid load forecast,the result is satisfied.This paper calculated the "Twelfth Five Year Plan" period of Yiwu power grid load data of each year, the reference is provided more accurate as" The Twelfth Five-Year Guideline" period of Yiwu power grid planning and construction of power grid.
