电力系统常用动态等值方法的比较与改进
Comparison and Improvement of Common Methods of Dynamic Equivalence in Power System
摘要
Abstract
In order to improve the accuracy and practicality of EMS, the dynamic equivalent methods was investigated in detail. In this paper, coherency method and evaluation method are investigated and compared in detail from the aspects of advantage, disadvantage, development status and development prospects. Finally, the evaluation method based on improved immune algorithm is applied in the engineering practice of real power system. Compared with the least square method, the dynamic equivalence method based on improved immune algorithm has higher precision and better effect, and can well meet the requirements of engineering applications.关键词
