Research On The States Of Electricity Supply And Demand In North China Grid

Based on the historical states of electricity supply and demand in NorthChina grid (NCG), especially based on the growth of max/mix load of NCGand Beijing-Tianjin-Tangshan network (BTTN) in 2005, and the statemacro-economic situation is take into account, than the 2005's increasetendency of NCG is presented. Subsequently, the 2005's load curves areanalysed, and weather evaluation method of PJM electric network of USA isused, the relevancy curve of load and weather of NCG and BTTN is drawed,and the 2005's load characteristic is maken. Later, the linear simulation andexponential simulation are used to simulate the load of NCG and BTTN in2006. At same time, due to the effection of the weather, feast, socialmovementthe, load simulation resulte is amended. Think about running ofnew units, examine plan, electricity limit and standby state, power balance iscalculate and the manage strategy is present.
