6.5.2 Analysis of power diagram
Given the high density of information, analysis of a power diagram is not too simple. For
better understanding, some points in time of a power diagram are analysed in what follows.
The example below shows how it works in a facility with limitation of the feed-
in to the public grid. This power limitation is a special feature that is used only in
cases where the network owner demands it. If requirements are imposed on
such an feed-in limitation, it can be controlled by the storage system.

Additional information:
• Nominal Power PV system: 5 kWp
• Feed-in Limitation: 50 % of the nominal power (here: 2.5 kW)
No. Description
1 It is dark (no generation (yellow)). Consumption (blue) and discharging (red) have the
same value. Consumption is therefore covered by the discharging of the storage system.
2 Generation (yellow) is approx. 1000 watts. This is used to cover consumption (blue). The
intelligent charging management system has postponed charging; the charging buffer is
needed to avoid breaching the feed-in limit. The energy that is not required is fed into the
grid.
