　　在競爭激烈的零售市場中,電源商正在尋求通過智能電表分析客戶的每一個(gè)用電數(shù)據(jù),這將為他們提供大量機(jī)會,以便在非常大量的智能電網(wǎng)中實(shí)現(xiàn)對客戶電力消耗需求的額外了解。通常,有大量的分析解決方案來呈現(xiàn)家庭的設(shè)施使用情況,但這些類型的解決方案并未提供準(zhǔn)確的信息。因此,我們嘗試對個(gè)體家庭能源消費(fèi)模式進(jìn)行全面分析,并設(shè)計(jì)一個(gè)家庭層面預(yù)測模型,利用歷史能耗數(shù)據(jù)預(yù)測未來有價(jià)值的實(shí)際需求和相應(yīng)的有關(guān)需求。本文提出了一種完全獨(dú)特的方法來預(yù)測配電系統(tǒng)中的輸電時(shí)間序列分析,該方法顯示了不同消費(fèi)行為的比例,以及相鄰時(shí)段內(nèi)不同時(shí)段的消費(fèi)水平。所提出的方法預(yù)測了客戶使用智能電表管理其家庭電力數(shù)據(jù)收集的合法性,并幫助客戶系統(tǒng)操作員檢測和控制負(fù)載需求。該模型在大型數(shù)據(jù)集中查找不同時(shí)期的各種功率趨勢。通過使用時(shí)間序列數(shù)據(jù)方法和預(yù)測模型的預(yù)測來進(jìn)行評估。結(jié)果表明,具有良好準(zhǔn)確性的預(yù)測可以幫助公司和最終用戶通過將功耗從高峰時(shí)段轉(zhuǎn)移到非高峰時(shí)段來控制其負(fù)載需求。應(yīng)用知識發(fā)現(xiàn)回歸模型,在一周內(nèi)明顯改善了電力趨勢消費(fèi),并幫助用戶改善客戶需求,如節(jié)能,低價(jià)和管理。
