Battery fluttering

[andig]

Here's another example of optimizer switching between batteries back and forth:

• discharging at midnight switches batteries twice
• same does discharging on day 2
• and charging on day 2 looks odd with the on-and-off of the red battery

It should- everything else equal- either charge both at the same time or first one then the other but not mix:

[ekkea]

if you add the c_priority property

        c_priority:
          type: integer
          minimum: 0
          maximum: 2
          default: 0
          description: Charging and discharging priority 0..2 compared to other batteries. 2 = highest priority.

to your batteries, you will get a clear prioritization. Just tried it with the above case (bat[1] with highest prio):

Does that meet your expectation?

[andig]

Can‘t we incentivise steady operation? I don‘t like this needs be configured?

But then, maybe its more a visual issue. Once we start making optimizer actionable however, this will become a real issue.

[ekkea]

If there is a charge-situation and multiple batteries are available having the same relevant properties (e.g. p_a, efficiency), somebody has to tell which one to charge. The optimiser cannot tell and will select randomly.
The priority parameter is one way to do this, it acts by creating an incentive (small target function contribution not included to the result reporting). A do-not-switch incentive would result in a similar behaviour, just randomizing the battery selection. Not sure if that would be an advantage?
In that case, we could simply assign default priorities if none is given 🤔

[andig]

The optimiser cannot tell and will select randomly.

I absolutely understand stand. I‘m only asking for a small penalty for switching the devices- below the order of financial impact.

A do-not-switch incentive would result in a similar behaviour, just randomizing the battery selection. Not sure if that would be an advantage?

It would at least look deterministic.

That said, I‘m open if this is to be fixed. Worst case we‘ll need to hard-assign priorities.

[ekkea]

I get it. It's just that from the modelling point of view, it is much cheaper to work with priorities than to assign a penalty for switching. The latter will involve a whole bunch of binary variables. It is hard to predict how much additional computation that would cost, however, I would ask the question why we think the "switch-inhibit" would be better than the "priority-stack". I do not see a significant difference in the result. Isn't the diagram above showing exactly the behavior you are asking for? If not, what should be different?
BTW, both approaches (would) apply a small penalty below the order of financial impact - there is no difference there. And, as said, I can assign default priorities so that configuration is not necessary as long as the user does not care about the sequence.

[mfuchs1984]

Ein eventuell verwandtes Phänomen: Stark schwankenden Ladeleistung bei "konstanter" Erzeugung. Führt im Endeffekt ab etwa 12 Uhr zu einer Phasenumschaltung nahezu alle 15 Minuten. Für hochwertige Wallboxen sollte das kein Problem darstellen, aber einige Autos steigen bei vielen Unterbrechungen und Phasenumschaltungen irgendwann aus. Zudem entsteht jedesmal eine Ladepause.

Das Konzept der Phasenumschaltung ist dem optimizer natürlich nicht bekannt. Wenn sich das nicht mit der gleichen Maßnahme wie hier angedacht verbessern lässt, wäre es eventuell möglich, hohe Ladeleistung zu belohnen, das ist ja auch generell effizienter.

[mfuchs1984]

Sorry for switching to German...
