【正文】 在實際情況下MPPT性能沒有顯示，或是其性能沒有充分研究以確定最優(yōu)功率偏差。 總結(jié)本文描述了一種新的風(fēng)力發(fā)電最大功率跟蹤系統(tǒng)，由 高效Buck型DC/DC變換器和基于單片機的控制單元組成。該方法有以下優(yōu)點：1）無需風(fēng)電最優(yōu)功率特性或風(fēng)速的測量；2）風(fēng)電機運行在變速狀態(tài)，同恒速系統(tǒng)相比，減輕了轉(zhuǎn)軸、齒輪的壓力。該方法不依賴于風(fēng)速或轉(zhuǎn)速的額定值，也不依賴于DC/DC變換器的額定功率。該系統(tǒng)的實驗結(jié)果表明，與經(jīng)由整流器直接和電池組相連的風(fēng)電機相比，此風(fēng)電機輸出功率提高了11%50%。該方法可以更好地開發(fā)可利用風(fēng)能， m/s的低風(fēng)速范圍內(nèi)，相比之下電池整流器結(jié)構(gòu)的功率則較低。該方法可以擴展到電池充電管理或附加可再生能源(RES)控制等領(lǐng)域。適當(dāng)改進(jìn)后，還可以控制風(fēng)能轉(zhuǎn)換并網(wǎng)系統(tǒng)中的DC/AC逆變器。參考文獻(xiàn)：[1] , , and , Power variation control of a wind turbine generator using probabilistic optimal control,include feedforward control from wind speed, Wind Eng., , , ,.[2] , Wind Energy Conversion Systems .
