Study On Long Term Load Forecasting Of Power Grid In Anyang County

In recent years, with the rapid development of our social economy and the electric power market, the importance of load forecasting has become increasingly prominent, which has become an important part of the power management system.Power load forecasting is mainly for the power supply of the pre arrangement, firstly we can understand the load time and quantity, so as to arrange power generator overhaul and maintenance of order; secondly, according to the load forecasting for power grid construction plan, gradually into the new unit, to meet under the new load prediction appears for the power system design,set aside power supply capacity, prolong the life of technology system, and lay a solid foundation for power grid planning work.Therefore, the data from load forecasting it is very important and far-reaching significance for control of the whole power system planning and operation etc.The accuracy of load forecasting is the key index for them. In the long term power load forecasting is the basis of power grid planning work. The operation of power system planning and decision-making, economic good requires accurate power load forecasting.Accurate load forecasting can provide strong data support and technical support for power engineering construction, and it is very important to the security and economy of power system reliable good operation and healthy national economy rapid development.The traditional prediction method is relatively mature, the prediction results have certain reference value, but to further improve the prediction accuracy, you need to make some improvement to the traditional method, at the same time, along with the progress of modern science and technology, the gradual deepening of theoretical research, the emergence of new interdisciplinary theory based on the Grey theory, the theory of expert system, fuzzy mathematics etc, they provide a solid theoretical foundation and basis for the rapid development of mathematical load forecasting.This paper firstly introduces the load forecasting significance and the domestic and foreign theory development, expounds the factors influencing the long-term load forecasting, and power load forecasting methods and steps. According to the actual situation of Anyang county area, with emphasis on the application of Grey theory and its improvement in the power network of Anyang County in the mid and long-term load forecasting, developed software for Anyang county power grid load forecasting, analyses and summarizes the method,points out the direction of future research.
