This paper discusses implications applying different net methods on prosumer’s grid, and subsequently effect costs self-consumption. The differ whether netting based each individual phase (or overall flow) interval used settlement. Besides describing illustrating those differences, real data from Danish household to quantify their impact. Results show that self-consumption increases 38% 53%, when moving instantaneous per hourly summation netting. corresponding annual imports decrease 1459 kWh 1087 kWh. economic quantified discussed, we savings at least €50 can be achieved by simply switching smart meter.
