One goal of grid coupled microgrid operating strategies is to reduce the maximum power drawn from the utility grid. This kind of operating strategy is called e.g. "peak load shaving", "peak power reduction" or just "peak shaving" and is applied to diverse applications and systems. This paper presents a method to determine the dependence between the maximum residual power and the respective required energy. Applied to operational strategies, this approach facilitates to find a plausible threshold for the peak power reduction. This method is broadly applicable to similar applications, e.g. for peak-shaving of PV power to limit the maximum feed-in power into the grid.
