Abstract

Paper presents features of renewable energy sources (RES) that have unstable nature. Therefore the RES are connected to stiff grid that stabilizes the AC voltage and provides power in case of low level power produced by the RES. The paper proposes to use an adjustable speed generation system operating in common microgrid. The adjustable speed generation system produces high quality AC power with high efficiency that makes whole system more modern. In case of high step load at low speed the adjustable speed system us not able to produce stiff voltage. Therefore a hybrid adjustable speed generation system is applied. Application of energy storage supplying the DC link of the adjustable speed generation system converter makes output AC voltage not sensitive to any step load.

调速解耦发电系统的性能研究
本文介绍了具有不稳定性的可再生能源的特点。因此,RES连接到刚性电网,稳定交流电压,并在RES产生低电平电力的情况下提供电力。本文建议在普通微电网中使用可调速发电系统。调速发电系统生产高质量、高效率的交流电源,使整个系统更加现代化。在低速高阶跃负载的情况下,调速系统不能产生刚性电压。因此,采用混合调速发电系统。采用储能供电调速发电系统变换器直流环节,使输出交流电压对任何阶跃负载都不敏感。
