摘要
能源运输体系是目前中国经济体系中的一个薄弱环节。中国传统的能源运输体系包括铁路、公路和海运,已经不能满足日益增长的能源运输要求。构建包含输电网络在内的现代能源综合运输体系成为当务之急。中国地域辽阔,能源资源与需求逆向分布,能源综合运输体系除了承担基本能源输送功能之外,还可肩负能源和环境资源优化配置的功能。本文分析能源运输系统现状后发现,目前以铁路为主、以运煤为主的能源运输系统并非最优。通过构建模糊多目标多指数运输模型,综合考虑能源外部成本以及时间成本、损耗和投资等各个因素,本文得出最优的能源运输体系。实现这一最优体系,需要改变现有电力就地平衡的布局原则,提高区域间输电比例和输电效率。
The current system of energy transportation is a fragility part for the China' s economic development. Traditional energy transportation system including railway, highway and water transportation can not satisfy increasing energy transportation requirement. It is an urgent matter to construct a modem energy transportation system that integrates electricity transmission. China is a large country and its energy resource distribution is very uneven. In addition to performing basic function of energy transportation, the proposed modem integrative energy transportation system will play an important role in optimal allocation of energy and environmental resources. By analyzing the problems of current energy transportation in China, we found that the current transportation system, which mostly relies on railway coal transportation, is not the best choice. In this study, applying a fuzzy multi-objective and multi-index transportation model, we propose an energy transportation system to optimize time cost, system loss and investment requirement. The proposed integrative energy transportation system will require changes of present power plant location principle that balances power demand and supply at local level. The new integrative energy transportation system will result in increasing the share and efticiency of power transmission between regions.
