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.

Additional information:
• Nominal Power PV system: 5 kWp
• Feed-in Limitation: 50 % of the nominal power (here: 2.5 kW)

Description
This legend shows which energy flows are displayed in which colour in the graph (f. e.
consumption is shown in blue).
„ Clicking on the desired energy flow (e.g. consumption) shows or hides this flow in the
graph.
„ Clicking on one of the buttons below the graph allows you to navigate to previous or
later time frames. By clicking on < 1 Day for example the specified period will scroll
back one day.
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.

Description
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.
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.
