Svrha projekta je smanjiti troškove električne energije korisnicima u zgradarstvu te omogućiti korisnicima elektroenergetske mreže aktivno sudjelovanje u pogonu sustava, čime se povećava njegova sigurnost. Navedeno će se postići razvojem umreženog stacionarnog sustava za pohranu energije u baterijama. Proizvod ima tri osnovne značajke: i) smanjuje vršnu potrošnju korisnika mreže; ii) prebacuje potrošnju iz skuplje (dnevne) u jeftiniju (noćnu) tarifu; iii) omogućuje sudjelovanje u pružanju rezerve operatoru sustava. Predmetni proizvod od velike je važnosti za moderni elektroenergetski sustav jer omogućuje integraciju veće količine obnovljivih izvora energije. Naime, u klasičnom elektroenergetskom sustavu potrošači su bili pasivni, a zadatak upravljivih konvencionalnih generatora (plinski, nuklearni, termo i hidro agregati) bio je pratiti krivulju potrošnje sustava. Porastom udjela obnovljivih izvora energije sve je više neupravljivih i slabo upravljivih proizvođača električne energije (vjetroelektrane i solarne elektrane) te se balansiranje sustava prebacuje na stranu potrošnje koja postaje aktivni sudionik elektroenergetskog sustava. Aktivni potrošači koji mogu pomicati svoju potrošnju u vremenu, tako da koincidira s proizvodnjom iz obnovljivih izvora energije, ključni su za vrlo visoki udio proizvodnje električne energije iz obnovljivih izvora, te posljedično održivi razvoj modernog društva. Balansiranjem sustava aktivni potrošači električne energije s baterijskim spremnicima smanjuju izdatke za električnu energiju. Naime, potrošači kategorije poduzetništvo, odnosno potrošači čija priključna snaga iznosi preko 20 kW, plaćaju tzv. angažiranu snagu, odnosnu vršno opterećenje koje ostvare tijekom mjeseca. Korištenjem spremnika energije koji se prazni tijekom vršnog opterećenja potrošač smanjuje naknadu za angažiranu snagu. (Croatian)

The aim of the project is to reduce the cost of electricity to users in the building sector and to enable users of the electricity grid to participate actively in the system’s operation, thereby increasing its security. This will be achieved by developing a networked stationary energy storage system in batteries. The product has three basic features: and) reduce the peak consumption of network users; II) switches consumption from the more expensive (daily) in the low priced (night) tariff; III) allows for participation in the provision of a reservation to the system operator. The product concerned is of great importance for a modern electricity system as it allows for the integration of more renewable energy sources. Indeed, in the classic electricity system, consumers were passive and the task of operating conventional generators (gas, nuclear, thermoand hydro) was to monitor the system’s consumption curve. The increase in the share of renewable energy sources is becoming more and more non-manageable, poorly managed electricity generators (wind turbines and solar power plants) and shifting the system shifting to the consumption side of the power system player. Active consumers who can move their consumption at a time, in such a way that they gamble with generation from renewable energy sources, are crucial for a very high share of renewable electricity generation and, as a result, the sustainable development of modern society. Balancing the system of active electric consumers with battery tanks reduces the cost of electricity. Indeed, consumers of categories of entrepreneurship, i.e. consumers with a power that are more than 20 kW, pay for what is known, the peak load underlying they achieve in the month. Using the energy reservoirs that is empty during peak hours, the consumer shall reduce the charge for the service power. (English)
