Load Forecasting And Pricing Research For Smart Grids

As an important part of the power grid,the smart grid load forecasting has a far-reaching impact on the national economy,energy conservation and emission reduction and sustainable development of the power industry.With the progress of society,and constantly improve the level of information resources and global issues have become increasingly prominent,how to scientific and sustainable development of the power grid,improve the level of intelligent power grid,transmission by a single carrier into multiple functions as a large distribution network.Power generation,transmission,substation,power distribution and efficient operation with the market Chinese energy shortage,uneven distribution,rapid development of the social situation,stable and efficient intelligent power grid,is the inevitable choice for sustainable economic development and national security.For the management of China's electricity forecasting,the new energy distribution has been developed rapidly,and the flexible and reliable access and delivery.But at the same time there are some new challenges,user diversity demand,user peak load growth,and other issues.This paper focuses on the smart grid load forecasting and pricing research to make the experiment and its research.And expounds the power load characteristics at home and abroad and the prediction effect(load intension,load analysis,load characteristics influence factors),short term load forecasting method(ultra short term load forecasting,time net method,BP neural network,support vector machine model prediction method,the prediction method,long-term prediction method)the power load(medium and long term load forecasting,multiple linear regression,gray model prediction method,combination forecasting model based on the proposed method)power load forecast method.At the same time,combined with the smart grid and power load characteristics,construct the pricing model of the smart grid,in order to reduce the power of terminal customers The use of cost,improve the management efficiency of power supply enterprises,optimize the energy structure of our country to provide a certain theoretical basis.
