v0.6.3

Frequenz Component Graph Release Notes

Upgrading

• consumer_formula() and producer_formula() no longer clamp their results. The clamps assumed the sign of active power, so they replaced valid values of other metrics, such as reactive power, with zero.
  • The consumer formula was wrapped in MAX(…, 0.0). It can now be negative, for example when unmodeled production or a measurement mismatch is larger than the consumption. To get the old result, wrap the formula as MAX(<formula>, 0.0).
  • Each producer term was wrapped in MIN(…, 0.0). A producer that draws power now adds a positive value instead of zero, so the total can be positive. For example, PV producing 10 kW and a CHP drawing 2 kW used to give -10 kW and now give -8 kW. There is one exception: when the two share a meter below the grid meter, that meter sends data, and disable_fallback_components is off, the meter measures them together, so they gave -8 kW before too. Wrapping the total as MIN(<formula>, 0.0) clamps the total at zero, but it still differs from the old result when one producer draws power while another produces.
  • With include_phantom_loads_in_consumer_formula, the consumer formula is unchanged: it still clamps each of its terms at zero.

What's Changed
