Mana-i-wela-i-mana no ka PV luna

Ua loiloi nā kānaka ʻepekema ma Sepania i ka hiki ʻana o ka 'mana-to-heat-to-power storage' i loko o kahi hoʻonohonoho solar hale ma Madrid.Hiki i ka ʻenehana ke hōʻemi i nā bila uila ma mua o 70% a loaʻa iā 12 a 15 mau makahiki uku uku, e like me ka poʻe noiʻi.

Ua noiʻi nā mea noiʻi ma ke Kulanui Polytechnic o Madrid i ka hiki ke mālama i ka mana i hana ʻia e ka lā ma luna o ka hale ma ke ʻano he wela a laila hiki ke hoʻohana ʻia e hana i ka mana inā ʻaʻole ʻā ka lā - 'power-to-heat-to-power storage,' a i ʻole ʻenehana PHPS.

ʻO ka ʻōnaehana hale ma Madrid i aʻo ʻia e ka poʻe ʻepekema i loaʻa kahi hana maikaʻi loa,ʻumehana wela hoʻoheheʻe ʻiaa me nā mea ʻohi wela o ka lā.

ʻO ka ʻōnaehana 'trigeneration', a i ʻole ka ʻenehana hui ʻana, ka wela a me ka mana (CCHP) ʻelua ʻano o ka hale kūʻai wela: kahi haʻahaʻa a i ʻole ka pae waena no ka wai wela a me ka hoʻomehana ākea a me kahi hale kūʻai wela kiʻekiʻe no ka wela a me ka mana. hanauna.Hiki ke hoʻohana ʻia ka wela i hana ʻia ma mua no ka hoʻoluʻu ʻana a me ka makemake hoʻomehana.

Hoʻokumu ʻia kahi hihia kuhikuhi ma ka hoʻohana ʻana i ka mana grid me kahi pā wela hoʻokele uila no ka hoʻoluʻu.

Nā kumu

Ua ʻōlelo ka hui ʻo Madrid i nā mea me kake kumukūʻai o ka mana grid a me ka wahiea ʻo ke kumu kūʻai a me ka hoʻonui ʻana o nā papa hana PV e hoʻopili i ka nui kūpono o nā ʻōnaehana trigeneration.Ua manaʻo ka poʻe noiʻi i kahi kumukūʻai €900-1,200/kW no nā ʻōnaehana PV a hoʻokumu i kā lākou manaʻo o ka loaʻa kālā PHPS ma ka hopena o ka mālama uila.

Hiki i kahi ʻōnaehana mālama mana-i-wela-i-mana ke hoʻokele i ka mālama uila ma mua o 70%, e like me ka poʻe noiʻi, akā e koi ana i 12-15 mau makahiki e uku nona iho."He ʻoiaʻiʻo kēia inā ʻo ka hoʻololi ʻana i ka wela-i-mana [efficiency] haʻahaʻa haʻahaʻa (20-30%), inā ʻoi aku ka maikaʻi o nā kūlana waiwai," wahi a nā mea noiʻi.

Ua ʻae ka hui ʻo Madrid i ka lilo ʻana o ka wela ma ka hale kūʻai wela wela, ʻo ia hoʻi, ʻo ka PHPS ka manaʻo he 40-60% wale nō."ʻO nā ala e hiki ai ke hōʻemi i kēia mau poho, ʻo ia ka hoʻomohala ʻana i ka moʻolelo, nā hale kūʻai wela ultra-dense i nā haʻahaʻa haʻahaʻa haʻahaʻa, a i ʻole nā ​​​​pūnaewele wela ʻoi aʻe," wahi a nā mea noiʻi.

Hōʻike ʻia nā ʻike o ka hui ma ka haʻawinaʻIke ʻenehana-economic o ka mālama ʻana i ka mana-i-wela-i-mana a me ka trigeneration ma ka ʻāpana noho.r,paʻi ʻia maHoʻohana i ka ikehua ma ka pūnaewele ScienceDirect.
