戶儲的含義是什么？
戶儲就是戶用儲能，也稱“家儲”，它是一種用于家庭用戶的儲能系統(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，多余的電能則存儲在蓄電池中，夜間則使用蓄電池供電，從而減少電費支出并保障用電的穩(wěn)定性。戶儲系統(tǒng)在全球儲能市場中占據(jù)重要地位，尤其在歐洲和美國市場。
戶儲系統(tǒng)在技術(shù)路線上通常采用電化學儲能，具有裝機規(guī)模靈活、產(chǎn)業(yè)鏈條成熟、安裝運維簡便等優(yōu)點。此外戶儲電源的核心優(yōu)勢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，滿足民用場景的待機功耗需求。
市場驅(qū)動力
峰谷價差拉大、儲能成本下降、FIT到期等因素都將驅(qū)動家儲經(jīng)濟性進一步提升，同時若VPP模式成熟，將為家儲帶來更高額的收益。
直接補貼：政對家儲配置給予直接補貼，如美國ITC政策給予配套光伏的儲能項目以稅收抵免，日本、澳大利亞等國家也均推出針對家儲的直接補貼政策以提升其經(jīng)濟性。
分時電價機制：美國加州、澳大利亞、意大利等國家均設(shè)有分時零售電價機制，在中午時段光伏發(fā)電量大、用電需求小，居民電價較低；傍晚時分光伏發(fā)電量驟減、用電需求快速提升，分時電價上升。戶用光伏配置儲能后，可在中午時分將光伏多余發(fā)電量對電池充電，并在傍晚家庭用電需求高峰時進行放電，減少傍晚時分（高電價時段）購電量，降低家庭用電成本；對于單獨配儲用戶，也可在電價低谷時間內(nèi)對電池充電并在高電價時段向電網(wǎng)放電實現(xiàn)套利。
