混合光伏-風(fēng)力系統(tǒng)由太陽能光伏,風(fēng)力發(fā)電機(jī)組,逆變器,電池和其他組件組合而成。一旦電力資源(風(fēng)能和太陽能)充足,所產(chǎn)生的多余電能需由電池消納,直至電池完全充電。電池作為電能儲存單元是任何隔離式可再生能源系統(tǒng)中最關(guān)鍵的部分。電池管理直接決定系統(tǒng)運(yùn)行的效率和優(yōu)化程度。因此,當(dāng)可再生能源(太陽能和風(fēng)能)不能滿足負(fù)載需求時,電池可以作為電源供電,直到電池能量耗盡。混合太陽能PV風(fēng)微電網(wǎng)框架的運(yùn)行依賴于單個組件。本文所建模型的混合動力系統(tǒng)由于其互補(bǔ)性而成為風(fēng)光互補(bǔ)系統(tǒng)。該系統(tǒng)主要由太陽能和風(fēng)力發(fā)電機(jī)組,蓄電池和電力電子轉(zhuǎn)換器組成。當(dāng)太陽能和風(fēng)力發(fā)電機(jī)組的輸出超過負(fù)荷需求時,多余的能量儲存在電池中,以便在發(fā)電量不滿足負(fù)荷需求時使用。因此,電池充放電控制對于提高系統(tǒng)效率和降低成本具有十分重要的意義。建模系統(tǒng)以約3KW的風(fēng)力和1KW的太陽能作為可再生能源。為了能夠從每個部件獲得最佳輸出,首先我們對單個部件進(jìn)行建模,通過評估它們的組合,以滿足所需的可靠性。本研究提出了一種基于模糊邏輯控制器的智能電池能量管理系統(tǒng),選擇三角隸屬函數(shù)來配置模糊邏輯控制器。這種基于控制器的電池管理框架專為有效的電力使用而設(shè)計。...
