为充分发挥分布式电源(distributed generation,DG)优势又保证对负荷经济、可靠供电,在分析各类DG与地区负荷特征基础上,综合考虑经济性、电压质量、供电可靠性和环境效益,提出一种DG与负荷相适应的特征匹配方法,可简单方便地对DG与地区负荷的适应性进行定量分析,为不同负荷地区DG的优选提供指导。算例结果表明:该方法准确直观,可综合考虑各种各样的条件与限制因素,给出较为合理的匹配方案,从而验证了所提方法的可行性与实用性。

In order to completely utilize distributed generations （DGs） and ensure stable and economical operation of the loads, a feature matching method based on the analysis of the features of various DGs and region loads is developed. The proposed method mutually adapts DGs and loads by comprehensively considering various facts, in terms of economy, voltage quality, supply reliability and environmental benefits. The method has the ability to easily and quantitatively analyze the adaptability of DGs and region loads, and provide guidance for DGs＂ selections in different load regions. The results demonstrate that the proposed method is accurate and intuitive and is able to provide a reasonable matching program by taking into account of various conditions and limitations, which can verify the feasibility and practicability of the proposed method.
