Abstract
In this study, the penetration effect of wind generation on voltage stability in a weak multi machine power system has been investigated. In terms of static and dynamic voltage stability, the most critical bus of IEEE 10-machine 39-bus system has been determined by using sensitivity analysis. The comparison has been made for various wind power penetration levels. It is shown if a large amount of wind power is integrated into power system, the system stability will be deteriorated. In the paper, a static synchronous compensators (STATCOM) is proposed to improve the stability. The calculations and simulations have been conducted by DIgSILENT Power Factory 15.0. Comparative simulation results show that the STATCOM can effectively increase voltage stability margin of the AC system which was considerably decreased due to wind power's penetration.
本文研究了风力发电对弱多机电力系统电压稳定性的渗透效应。在静态和动态电压稳定性方面，通过灵敏度分析确定了IEEE 10机39总线系统中最关键的总线。对不同的风力发电渗透水平进行了比较。结果表明，如果大量的风电接入电力系统，将会使系统的稳定性变差。本文提出了一种静态同步补偿器(STATCOM)来提高系统的稳定性。计算和模拟由DIgSILENT Power Factory 15.0进行。对比仿真结果表明，STATCOM可以有效地提高交流系统的电压稳定裕度，而风力发电的渗透降低了交流系统的电压稳定裕度。
