分布式能源技术与发展现状

Technologies and Development Status for Distributed Energy Resources

分布式能源具有能源利用效率高、环保、可靠性高的优点,是实现能源可持续发展的关键。将分布式能源分为热电联产、可再生能源、储能和燃料电池四大类,从技术原理和发展现状两个方面对其进行讨论。另外,分布式能源追求能源、环境和经济三者的效益最大化,而影响用户选择分布式能源的主要因素是经济性。

Distributed energy resources(DERs) is key to sustainable development of energy, which has the advantages of high energy efficiency, environmental protection and high reliability. This paper dividing DERs into four types: combined heat and power, renewable energy, energy storage and fuel cells and discusses it from two aspects: technical principle and development. In general, DERs seek to maximize the benefits of energy, environment and economy. But the main factor affecting users’ choice of distributed energy is economy.
