  With the increasing penetration of renewable resources in the distribution
grid, the demand for alternatives to grid reinforcement measures rises. One
possible solution is the use of battery systems to balance the power flow at
crucial locations in the grid. Hereby the optimal location and size of the
system has to be determined in regards of investment and grid stabilizing
effect. In this paper the optimal placement and sizing of battery storage
systems for grid stabilization in a small distribution grid in southern Germany
with high PV- penetration is investigated and compared to a grid heuristical
reinforcement strategy.
