Complex System Modeling for Coal Demand in Electricity Industry

Based on the analysis about the complex structural features and the dynamic feed-back of the coal demand system in the electricity industry, it constructs SD model of coal demand in the electricity industry and conducts emulation simulation. Study shows that the factors influencing coal demand in the electricity industry are so complex that the speed of economy, technological advances in energy-saving and policy regulating are playing important roles. In order to control the over-increase of coal demand in the electric industry, focus should be on adjusting the industry structure, lowering investment rates and perfecting investment structure. It is necessary to regulate the development of coal and electric power, advocate the contributions to energy-saving and consumption reduction, etc..
