Razvoj distribucijskega omrežja v luči »Nacionalnega energetskega podnebnega načrta«

PERPAR, JAN (author), Mihalič, Rafael (mentor)

Distribucijska podjetja bodo predstavljala pomembno vlogo pri razvoju distribucijskega omrežja, saj bo zanesljivost in kakovost električne energije predstavljala pomemben del pri doseganju evropskih in slovenskih ciljev glede podnebno nevtralne družbe. Za tako hiter razvoj tehnologij in posledično povečano povpraševanje po električni energiji bo potrebno sorazmerno hitro prilagajanje, razvoj, širitev in nadgradnja obstoječega srednjenapetostnega omrežja in predvsem nizkonapetostnega omrežja, pri čemer se bo manifestirala množična elektrifikacija prometa in ogrevanja. Diplomska naloga je sestavljena iz prvega dela, v katerem govorimo o nacionalnih načrtih za prihodnost, ki so v skladu z evropsko energetsko in podnebno politiko o razogljičenju družbe in doseganju podnebno nevtralne družbe. Nacionalni energetski podnebni načrt je predstavljen skozi pet razsežnosti energetske unije. Pod prvi del pa spada tudi predstavitev nacionalnega standarda SIST EN 50160, ki podaja mejne vrednosti parametrov napetosti na mestu odjema. V srednjem delu govorimo o sestavi distribucijskega načrta in bolj podrobnem pregledu nizkonapetostnega omrežja. Poleg tega zajema še postopek pridobitve koničnih moči gospodinjskih odjemalcev na področju distribucijske enote Trbovlje, ki smo jih uporabili za namen diplomske naloge – tj. pregled stanja na nizkonapetostnem omrežju z usmeritvami za prihodnost. Sledi drugi, analitični del diplomske naloge, v katerem so predstavljeni problematika padcev napetosti v omrežju in način ter namen izračuna padcev napetosti, katerega rezultati se odražajo v stanju na nizkonapetostnem omrežju DE Trbovlje. Poleg dejanskega stanja pa je še predstavljeno predvideno stanje NN omrežja glede množične elektrifikacije prometa in ogrevanja. Narejeni so izračuni, v kakšnem stanju bo omrežje do leta 2030, ko bo potrebno vgraditi nove toplotne črpalke v gospodinjstva in uvesti električna osebnih vozila v gospodinjstva z namenom, da bi dosegli zastavljene nacionalne cilje. Na koncu so predstavljene možne rešitve, ki se jih bodo posluževala distribucijska podjetja za reševanje problematike padcev napetosti zaradi hitrega prehoda v podnebno nevtralno družbo. Zadnji del pa predstavlja pregled stanja in predvidene finančne stroške, ki bi pestili distribucijska podjetja (tukaj govorimo predvsem o stroških distribucijske enote Trbovlje) zaradi nacionalnih načrtov, ki bi se jim morala hitro prilagajati tako distribucijska podjetja kot tudi odjemalci sami.

• Title: Development of distribution network in light of "National Energy Climate Plan"

Abstract

Distributive companies will represent an important role in development of the distributive network, because reliability and quality of electric energy will represent an important role in achieving European as well as Slovenian goals regarding a climate-neutral society. Such rapid development of technologies and consequently increasing demand for electric energy will require a relatively quick adaptation of development, as well as expansion and upgrading of the already existing medium and low voltage network, where mass transport electrification and heating will manifest. This diploma consists of two parts. The first part is about future national plans, which are in conformity with European energetic and climate policy, dealing with decarbonization of society and achieving climate - neutral society. The national energy climate plan is presented through five dimensions of energy union. The first part also deals with SIST EN 50160 national standard presentation, which gives the values of voltage parameters at the place of consumption. The middle part deals with composition of distributive plan and more detailed overview of the low voltage network. In addition, it includes the process of achieving peak powers of household consumers in the area of Trbovlje distribution unit, which we used for the purpose of the diploma thesis. It gives an overview of the low voltage network state, with future directions. The second part, analytical part of my diploma, introduces issues of voltage drops in the network, as well as the way and the purpose of calculating voltage declines which results reflect in the state/condition in low voltage network of DE Trbovlje. Besides the actual state, the projected state of low voltage network, regarding mass traffic electrification and heating is presented. Calculations of what network condition will be by 2030 are made. By the time, it will be necessary to install new heat pumps into households and introduce electric vehicles in order to achieve the already set national goals. Possible solutions, used by distributive companies, to deal with problems of voltage declines, due to the rapid transition to a climate – neutral society, are also presented. The last part presents an overview of the state and estimates financial costs, which could threaten distributive companies (we are mainly dealing with the costs of the Trbovlje distribution unit), due to national plans, which both, distributive companies and customers would quickly need to adapt.
