The Coordination Of Urban Economy And Power Network Based On System Dynamics

As China's urban economic develop rapidly,the contradiction between economic development and power network become more and more prominent.How to effectively achieve the coordinated development between urban economy and grid is of great practical significance.First of all,this paper realizes the combination of system dynamics(SD) and econometric methodology.Based on SD method,it establishes the grid-economy model,from which we study the economy saturation of Beijing city,then,we get the load saturation based econometric methodology,which provides a reference for power network planning.Beijing's economy will reach its saturation point in 2036,and Beijing's load will reach its saturation point in 2038 due to the lag of economic development on power demand; Second,by analyzing the development of London,Tokyo,Beijing and Tianjing city's power grid and the relationship between grid and economic development of the above four cities,this paper set up the coordination model of city economic and grid development.The conclusion shows that the coordination between city economic and grid is more ang more optimized.
