Effect of the Quantity and Penetration of Energy Resources on the Incentivization of Grid-Beneficial Behavior in Prosumer Households

Abstract:
The increasing decentralization of energy generation in the wake of the energy transition poses new challenges for the stable operation of the electricity grid. Common households are no longer pure energy consumers but incorporate their own generation, making them so-called prosumer households. We investigate the effect of the pervasiveness of PV and battery storage units on the effectiveness of four mechanisms to incentivize prosumers to benefit the power grid operation with their devices while optimizing for their own costs. Our results are in line with previous works, showing that peak-price incentives can almost completely alleviate grid congestions in the investigated scenarios without imposing hard restrictions on prosumers decisions. Conditional power prices can alleviate all congestions if the added cost is higher than the feed-in remuneration, preventing all PV feed-in. The penetration of renewable energy sources has no significant effect on the effectiveness of each mechanism. Their distribution influences the amount of congestions in the reference scenario but the relative mitigation by the mechanisms remains constant.
