摘要

在分析风力发电系统和微型燃气轮机动态模型及运行特性基础上，提出利用可控的微型燃气轮机平滑风电功率波动从而改善电压质量的方法。建立了风力发电系统与微型燃气轮机互补发电的混合微电网系统模型，并对其控制策略进行了研究。在所建立的混合微电网系统中，风力发电系统承担馈线基荷，微型燃气轮机承担馈线剩余负荷并作为热备用，在风速变化时平滑风电功率波动，从而实现对母线电压的优化控制。对该方法进行了PSCAD仿真，仿真结果表明:出现阵风、渐变风等风速扰动时，系统电压波动可以得到有效抑制;在发生线路故障时，系统电压波动和电压恢复时间也能得到有效减小。

Abstract

Based on the analysis of the dynamic models and operating characteristics of wind power generation systems and microturbines，a method for smoothing the fluctuations of wind power by using controllable microturbines is proposed to improve the voltage quality.The model of the hybrid microgrid with wind power generation systems and microturbines is developed，and its control strategy is studied.In the hybrid microgrid，the wind power generation systems share the baseload of the feeders，while the microturbines share the remaining loads of the feeders for use as reserves to smooth the fluctuations of wind power during wind speed changing to achieve optimal control of bus voltage.The PSCAD-based simulation results of the proposed method show that should there be a gust of wind，a gradually changing wind or other wind disturbances，the system voltage fluctuations can be effectively suppressed;when the line goes faulty，the system voltage fluctuations and voltage recovery time can be effectively mitigated.
