Comparative Study On Energy Transmission Mode

With the rapidly growing economy, the energy demand increases greatly. Due to energy distribution imbalance in the space, part of the areas lack of energy resources, relying on energy call to ensure energy security. National energy strategy layout transfers to the Midwest to maintain healthy and stable development of economy. Because economic benefit and the external cost of different kinds of energy is different, the choice of energy transmission mode will directly affect energy production and consumption patterns, as well as the society, economy and environment of energy output area. Therefore, how to quantitatively measure the influence of different energy transmission modes has an important sense for the choice of energy transmission mode and the coordinated development of economy, energy and environment.This paper introduces domestic and foreign research status, as well as the related theories, which laid a solid theoretical foundation. Then the energy transmission driving force is analyzed from the national strategy and regional development two aspects. On the basis of the analysis of energy supply and demand spatial pattern, interregional energy transfer trend is discussed. Besides, comparative analysis of the effect of coal transport and power transmission on energy output area is performed. Afterward, a social economic-energy transmission-ecological environment system is established, and the influence elements of the energy transmission contrast are determined. This paper considers the impact on regional sustainable development caused by energy consumption transfer as a system, and uses system dynamics theory to identify system elements. The causal relationships between each factor are analyzed, the element causality diagram and system flow chart are constructed, and a system dynamics model of energy consumption transfer is set up. At last, taking Shanxi Province transferring coal and power energy for example, this paper simulates the effect of energy consumption transfer using system dynamics model, and compares the simulation results of different energy transmission mode.
