Commercial and Industrial (C&I) energy storage systems play a crucial role in maximizing the self-consumption rate of solar energy, reducing electricity expenses for industrial and commercial owners, and aiding in energy conservation and emission reduction efforts. These systems are categorized as user-side energy storage solutions, enabling enterprises to optimize their energy usage and become more sustainable.

Kuna miundo miwili ya msingi ya biashara ya kuendesha mifumo ya hifadhi ya nishati ya C&I. Katika mfano wa kwanza, watumiaji wa kibiashara na wa viwandani huweka vifaa vya uhifadhi wa nishati wenyewe, na kusababisha kuokoa moja kwa moja kwa gharama ya umeme. Hata hivyo, watumiaji hawa wanapaswa kubeba gharama ya awali ya uwekezaji na gharama za matengenezo ya kila mwaka. Mfano wa pili unahusisha makampuni ya huduma ya nishati kusaidia watumiaji katika mchakato wa ufungaji. Makampuni haya huwekeza katika kujenga rasilimali za kuhifadhi nishati na huwajibika kwa uendeshaji na matengenezo ya mifumo. Watumiaji wa viwandani na kibiashara basi hulipa kampuni za huduma ya nishati kwa gharama zao za umeme.

Utumizi wa mifumo ya uhifadhi wa nishati ya upande wa mtumiaji umepanuka kwa kiasi kikubwa, ikijumuisha matukio mbalimbali kama vile vituo vya kuchaji na kubadilishana, vituo vya data, vituo vya msingi vya 5G, nishati ya ufuo wa bandari, na ubadilishaji wa lori kubwa. Mifumo hii imekuwa muhimu katika kuruhusu vifaa hivi kufanya kazi kwa ufanisi huku ikipunguza athari zake kwa mazingira.

The structure of C&I energy storage systems typically involves separate Power Conditioning System (PCS) units and battery systems. The inverter boost unit consists of the PCS, grid-connected cabinets, and transformers. Containers housing the battery cabinets, confluence cabinets, and monitoring equipment provide independent power supply, lighting, temperature control, humidity control, fire protection, safety escape, and other automatic control and safety assurance units. Additionally, the power station requires a power system to provide self-consumption power for the energy storage unit and a booster station to facilitate grid connection.

Paneli za jua ni sehemu muhimu ya mifumo ya kuhifadhi nishati ya C&I. Muundo wao lazima ukidhi mahitaji ya kila siku ya matumizi ya umeme ya mzigo chini ya hali ya hewa ya wastani. Hii inamaanisha kuwa nishati inayotokana na paneli za jua inapaswa kuendana na matumizi ya kila mwaka ya mzigo. Walakini, ni muhimu kuzingatia kwamba sio nguvu zote zinazozalishwa zinabadilishwa kuwa matumizi ya umeme. Mambo kama vile ufanisi wa kidhibiti, upotevu wa mashine na upotevu wa pakiti ya betri wakati wa kuchaji na kutoa chaji lazima yahesabiwe.

Kwa kuzingatia mahitaji ya muda wa chini wa majibu ya mifumo ya hifadhi ya nishati ya C&I, betri za aina ya nishati hutumiwa kwa kawaida kutokana na utendakazi wao wa gharama, maisha ya mzunguko na muda wa kujibu. Kazi ya msingi ya betri ni kuhakikisha matumizi ya nguvu bila kuingiliwa wakati mionzi ya jua haitoshi. Uwezo wa kifurushi cha betri unaweza kutengenezwa kulingana na mahitaji na masharti mahususi ya kila mfumo, kwa kuzingatia vipengele kama vile mahitaji ya voltage, mabadiliko ya muda wa nishati, usuluhishi wa bonde la kilele, na nguvu mbadala kwa siku za mvua.

C&I energy storage inverters have a relatively simple function, primarily based on two-way conversion. They are smaller in size and easier to integrate with battery systems. The flexibility of these inverters allows for expansion based on future needs. With an ultra-wide voltage range of 150-750V, they can cater to various battery types such as lead-acid batteries, lithium batteries, and Lithium Iron Phosphate (LEP) batteries. In addition to basic converter functions, coupling functionality is crucial, including primary frequency regulation, fast dispatch of source, grid and load, and strong adaptability to achieve quick power response.

Wakati wa kuchagua PCS, ni lazima kuzingatia mahitaji ya mzigo. Mizigo kwa kawaida huainishwa kuwa ya kufata neno au ya kupinga. Mizigo ya kufata neno, kama vile mota zinazopatikana katika viyoyozi vya kati, konishi, na korongo, zina nguvu ya kuanzia ambayo ni mara tatu hadi tano ya nguvu iliyokadiriwa. Kwa hiyo, ni muhimu kuzingatia nguvu ya kuanzia ya mizigo hii wakati wa operesheni ya nje ya gridi ya taifa katika hatua ya kubuni ili kuhakikisha kwamba nguvu ya pato ya inverter inazidi mahitaji ya nguvu ya mzigo. Kwa programu zilizo na mahitaji madhubuti, kama vile vituo vya ufuatiliaji na mawasiliano, jumla ya nishati ya pato inapaswa kuwa jumla ya nguvu zote za mzigo.

The energy management system (EMS) for most C&I energy storage systems does not require grid dispatching, resulting in relatively basic functionality. The primary focus of the EMS is local energy management, supporting battery balance management, ensuring operational safety, enabling millisecond-level fast response, and facilitating integrated management and centralized control of energy storage subsystem equipment.

Tukiangalia mbeleni, kipindi cha kuanzia 2023 hadi 2024 kinatarajiwa kushuhudia kilele kipya katika maendeleo ya hifadhi ya nishati ya viwanda na biashara. Mahitaji ya mifumo hiyo, ndani na nje ya nchi, ni muhimu. Ingawa muundo wa ushindani haujajitokeza kikamilifu, soko liko kwenye hatihati ya kuzuka. Uhifadhi wa nishati ya viwandani na kibiashara una uwezo wa kuwa usanidi wa kawaida katika uzalishaji wa viwandani na wilaya kubwa za kibiashara, zenye nafasi ya kutosha ya ukuaji.
