能源效率是解决环境问题、增强经济竞争力和确保能源安全的关键因素,是实施可持续发展战略的优先选择。20世纪90年代我国引入“电力需求侧管理”(简称DSM),这一先进的思维方法和管理技术是从提高终端电能利用效率出发来提高能源效率的。其优越性在于:对政府,可以更合理有效地利用能源资源,发挥市场经济优化社会资源和配置的功能,同时控制环境质量;对用户,可以降低单位节电成本,减少电费支出,更加合理地用电并促进实现成本效益;对电力系统,可以避免新增电力成本和峰荷容量成本,减少对电力建设的投资。实行电力需求侧管理技术是一项一举多得的好事。
Energy efficiency is a key factor in solving environmental problems, enhancing economic competitiveness and ensuring energy security. It is a priority choice for implementing sustainable development strategies. In the 1990s, China introduced “Power Demand Side Management” (referred to as “DSM”). This advanced thinking method and management technology is to improve energy efficiency by improving terminal energy utilization efficiency. Its advantages lie in that it can use energy resources more rationally and effectively for the government, exert its function of optimizing the social resources and configuration of the market economy, and at the same time control the quality of the environment; for users, it can reduce the unit’s energy-saving cost and reduce the electricity bill, which is more reasonable. Electricity is used to promote cost-effectiveness; for power systems, new electricity costs and peak-to-charge capacity costs can be avoided, and investments in power construction can be reduced. The implementation of power demand side management technology is a good thing that can be done in one fell swoop.
