摘 要:將電能成本和用戶的需求與電能的質(zhì)量水平直接聯(lián)系起來,分析了考慮多質(zhì)量等級電能時發(fā)電商發(fā)電容量獲利情況,并通過算例進(jìn)行了驗證。結(jié)果表明發(fā)電商提高或降低電能質(zhì)量水平出售電能,而不是在用戶的目標(biāo)電能質(zhì)量水平時出售電能,從而獲得更大的經(jīng)濟(jì)利益,即實現(xiàn)了質(zhì)量持留,是容量持留的表現(xiàn)形式之一。
關(guān)鍵詞:電力市場;多質(zhì)量等級;發(fā)電容量;持留

Abstract: Connecting power cost and customers’ demand with power quality level directly, this paper analyzed profit-obtaining situations of power supplier’s generation capacity in consideration of multi-quality grade power. The calculation examples verified that power suppliers sold power according to ups and downs of the power quality level, not according to customers’ target power quality level, thus to obtain more economic benefit, which realized the quality withholding. It is one of indication forms of capacity withholding.
Key words: power market; multi-quality grade; generation capacity; withholding
