Abstract
S obzirom na porast integracije niskougljičnih tehnologija u distribucijskim mrežama potreban je razvoj alata koji analiziraju njihov utjecaj na tehno-ekonomske prilike u mrežama te omogućuju kvalitetno planiranje i vođenje distribucijskog sustava. U radu je dan kratak pregled i usporedba raznih modela optimalnih tokova snaga. Prikazan je model trofaznih optimalnih tokova snaga koji je pogodan za analizu niskonaposnkih mreža u kojima je zbog velikog broja jednofazno priključenih niskougljičnih tehnologija prisutna nesimetrija. Pomoću modela trofaznih optimalnih tokova snaga analiziran je utjecaj vrste priključka (jednofazni/trofazni) te udjela čvorišta sa instaliranim fotonaponom na kapacitet instalacije fotonapona u niskonaponskoj mreži. Također, analiziran je i utjecaj faktora poput lokacije izvora i oblika mreže na dosezanje strujno-naponskih ograničenja te su prikazane određene metode povećanja kapaciteta instalacije u distribucijskim mrežama. Na kraju su predstavljeni modeli upravljanja punjenjem električnih vozila čija fleksibilnost punjenja operatoru distribucijskog sustava omogućuje pogon sustava unutar dozvoljenih ograničenja, a korisnicima vozila određenu naknadu.
Abstract (english)
Considering the increase in the integration of low-carbon technologies in distribution networks, the development of tools that analyse their impact on the techno-economic conditions in networks and enable high-quality planning and management of the distribution system is needed. The paper provides a brief overview and comparison of various models of optimal power flows. The model of three-phase optimal power flows is presented, which is suitable for the analysis of low-voltage networks in which unbalance is present due to the large number of single-phase connected low-carbon technologies. Using the model of three-phase optimal power flows, the influence of the type of connection (single-phase/three-phase) and photovoltaics penetration level on the hosting capacity of photovoltaic installation in the low-voltage network was analysed. Also, the influence of factors such as the location of the source and the shape of the network on reaching the current-voltage limits was analysed, and certain methods of increasing the installation capacity in distribution networks were presented. At the end, electric vehicle charging management models are presented. The flexibility of charging allows the distribution system operator to operate the system within the permitted limits, and the users of the vehicle receive a certain fee.
