戶儲(chǔ)的含義是什么？

戶儲(chǔ)就是戶用儲(chǔ)能，也稱“家儲(chǔ)”，它是一種用于家庭用戶的儲(chǔ)能系統(tǒng)，它通常與戶用光伏系統(tǒng)結(jié)合使用，以分散電力需求和資源分布，提高可再生能源的消納率。

戶儲(chǔ)系統(tǒng)的工作原理是白天利用光伏發(fā)電直接供電，多余的電能則存儲(chǔ)在蓄電池中，夜間則使用蓄電池供電，從而減少電費(fèi)支出并保障用電的穩(wěn)定性。戶儲(chǔ)系統(tǒng)在全球儲(chǔ)能市場(chǎng)中占據(jù)重要地位，尤其在歐洲和美國(guó)市場(chǎng)。

戶儲(chǔ)系統(tǒng)在技術(shù)路線上通常采用電化學(xué)儲(chǔ)能，具有裝機(jī)規(guī)模靈活、產(chǎn)業(yè)鏈條成熟、安裝運(yùn)維簡(jiǎn)便等優(yōu)點(diǎn)。此外戶儲(chǔ)電源的核心優(yōu)勢(shì)在于低功耗和超寬輸入電壓范圍，這有助于提升整體續(xù)航能力，滿足民用場(chǎng)景的待機(jī)功耗需求。

市場(chǎng)驅(qū)動(dòng)力

峰谷價(jià)差拉大、儲(chǔ)能成本下降、FIT到期等因素都將驅(qū)動(dòng)家儲(chǔ)經(jīng)濟(jì)性進(jìn)一步提升，同時(shí)若VPP模式成熟，將為家儲(chǔ)帶來(lái)更高額的收益。

直接補(bǔ)貼：政對(duì)家儲(chǔ)配置給予直接補(bǔ)貼，如美國(guó)ITC政策給予配套光伏的儲(chǔ)能項(xiàng)目以稅收抵免，日本、澳大利亞等國(guó)家也均推出針對(duì)家儲(chǔ)的直接補(bǔ)貼政策以提升其經(jīng)濟(jì)性。

分時(shí)電價(jià)機(jī)制：美國(guó)加州、澳大利亞、意大利等國(guó)家均設(shè)有分時(shí)零售電價(jià)機(jī)制，在中午時(shí)段光伏發(fā)電量大、用電需求小，居民電價(jià)較低；傍晚時(shí)分光伏發(fā)電量驟減、用電需求快速提升，分時(shí)電價(jià)上升。戶用光伏配置儲(chǔ)能后，可在中午時(shí)分將光伏多余發(fā)電量對(duì)電池充電，并在傍晚家庭用電需求高峰時(shí)進(jìn)行放電，減少傍晚時(shí)分（高電價(jià)時(shí)段）購(gòu)電量，降低家庭用電成本；對(duì)于單獨(dú)配儲(chǔ)用戶，也可在電價(jià)低谷時(shí)間內(nèi)對(duì)電池充電并在高電價(jià)時(shí)段向電網(wǎng)放電實(shí)現(xiàn)套利。
