Lion Hirth Releases Paper on EV Smart Charging Rebound Peaks
Get up to speed
Lion Hirth published a working paper, pointing out that previous studies on price-optimized electric vehicle charging generally assumed that wholesale electricity prices are unaffected by electric vehicle load shifting, overestimating the rebound load peak problem in low-voltage distribution networks. This study conducts real-time electricity price simulations based on 2025 calibrated data from Germany. The results show that when the electricity price-load feedback is not considered, the peak of synchronized local grid imports increases by 260%, and after incorporating the equilibrium wholesale electricity price model, the increase drops to 5%; when vehicle-to-grid power delivery is allowed, the peak export increase drops from 115% to 6%.

- arXiv q-finSmart Charging without Rebound Peaks: How Wholesale Price Feedback Mitigates Distribution Grid Peaks Caused by Price-Responsive Electric Vehicles
Research on price-optimized electric vehicle charging commonly assumes that wholesale electricity prices are unaffected by EV load shifting, which overestimates the rebound load peak problem in low-voltage distribution grids. Real-time price simulations calibrated to German 2025 data show that when price-load feedback is ignored, synchronized local grid import peaks rise by 260%, while the increase falls to 5% after incorporating an equilibrium wholesale price model. When vehicle-to-grid export is allowed, the increase in export peaks drops from 115% to 6%.
