Because of its fluctuating nature, the feed-in of renewable energy sources into low-voltage distribution grids complicates the balancing of demand and supply. This carries the risk of grid instabilities causing damage to electronic devices and power outages, which eventually lead to deadweight losses. In principle, the problems arising from fluctuating feed-in can be solved by increasing demand elasticity or decoupling generation and consumption; for the first, an advanced metering infrastructure and, for the second, decentralized electricity storage are considered core enablers.
