Power‐frequency oscillation suppression algorithm for AC microgrid with multiple virtual synchronous generators based on fuzzy inference system
نویسندگان
چکیده
In the microgrid, virtual synchronous generator technology can significantly enhance anti-interference characteristics of system frequency and bus voltage, as well solve problems insufficient damping low inertia. However, active power oscillation caused by fluctuations grid faults threaten stable operation seriously. Therefore, for an alternating current (AC) microgrid multi-virtual (VSG) parallel system, improved control algorithm based on a fuzzy inference is proposed, which adjusts values inertia coefficient dynamically through logic rules to realize coordinated two. The enhanced VSG described in this research has substantial influence power-frequency suppression, decreases overshoot, shortens adjustment time, improves stability power, according simulation experimental findings.
