    Cost reductions of rooftop photovoltaics and battery storage, increasing retail electricity prices as well as falling feed-in remuneration provide strong incentives for many German households to engage in self-consumption. These developments may also affect the electricity system as a whole. Against this background, we jointly apply a prosumer simulation and an agent-based electricity market simulation in order to investigate the long-term impacts of a residential battery storage diffusion on the electricity market. We analyze different regulatory frameworks and find significant effects on the household level, yet only moderate system impacts. In the long run, the diffusion of residential battery storage seems difficult to govern, even under a restrictive regulation. In contrast, the way the batteries are operated may be easier to regulate. Policymakers and regulators should focus on this aspect, since a system-friendly battery operation supports the system integration of residential photovoltaics while having little impact on the households' selfsufficiency.

    In order to increase self-consumption (SC) more than half of the residential photovoltaic (PV) systems in Germany are installed with battery storage systems (BSS). The utilization of these BSSs however varies throughout the year and therefore they could be used for other services to further increase their profitability. Recent changes in regulation for frequency containment reserve (FCR) facilitate multi-use concepts and first aggregators are already prequalified for the German market. Against this background, we analyze the potential for the joint provision of FCR and SC increase from residential BSSs with a linear optimization model applied to 162 German households. Different scenarios including fixed shares of the BSS reserved for FCR, priorization of SC or a joint optimization of SC and FCR are examined. We find that fixed shares of FCR only lead to minimal additional financial benefits. Both, the joint optimization of FCR and SC and prioritizing SC lead to higher additional gains, while the loss in SC is low in both scenarios. Moreover, even when prioritizing SC still high shares of the BSS can be used for FCR. Only a significant increase in FCR prices leads to SC being sacrificed for higher FCR shares.
