Dvosmerna izmenjava električne energije V2G za razvoj storitev prožnosti z agregacijo voznega parka električnih vozil. (Slovenian)

The paper presents a vehicle-to-grid (V2G) technology. On an example of a vehicle fleet using the V2G technology, the ability of electric vehicles (EVs) is demonstrated to participate in flexibility services to ensure the grid stability. A simple simulation tool in Python with the PuLP library, is developed to calculate the optimal scheduling of the EVs charging and discharging. The optimization written with linear programming assures minimum number of EV charging and discharging hours while meeting the EVs and grid requirements. From the aggregator's point of view, we found that the most suitable use case is the one with the EVs charged at 20% at plug-in and the required state of charge at disconnection at 80%.

V članku smo raziskali koncept dvosmerne izmenjave električne energije med električnimi vozili (EV) in omrežjem (angl. vehicle to grid, V2G). Na primeru voznega parka, ki uporablja tehnologijo V2G, smo demonstrirali zmožnost sodelovanja EV v storitvah prožnosti in posledično zagotavljanja stabilnosti omrežja. Za iskanje optimalne razporeditve polnjenj in praznjenj EV za izbrani primer uporabe, smo razvili preprost simulator v jeziku Python s knjižnico PuLP. Cilj optimizacije, ki smo jo zapisali z linearnim programiranjem, je doseči najmanjše število ur polnjenj in praznjenj EV, da so izpolnjene vse zahteve EV in omrežja. Z vidika agregatorja smo za izbrane primere uporabe ugotovili, da je primer službenega parkirišča z 20% napolnjenostjo (angl. state of charge, SOC) ob priklopu in zahtevanem SOC ob odklopu na 80% najustreznejši za sodelovanje v storitvi V2G.
