Dynamic feed-in from prosumer households with batteries considering spot market prices

Abstract:
Prosumer households with photovoltaic systems often use battery systems to maximize their self-consumption. The current situation on the energy market is usually irrelevant for that, as households usually make use of a guaranteed constant feed-in tariff and purchase electricity for a constant electricity price. If prices for consumption and feed-in are dynamized based on spot market prices and the battery control is optimized accordingly, revenue increases of more than 60 % are possible with the same technical equipment. If spot market prices remain at the current level, a new market for direct marketing of electricity from residential PV power plants could emerge. This would be beneficial to the energy system since the results show that prosumer households tend to feed-in more power during a high residual load when optimizing towards spot market prices.
