Tariff Compare - Model Octopus Intelligent Flux more realistically

[chibbert]

Firstly, thanks to all the team for an absolutely amazing project! It's blown me away how featured predbat is, and how (relatively) easy it has been to get it working with my givenergy solar+battery system, nicely working with home assistant.

I've been having a play around with the tariff comparison feature, and it seems that for intelligent flux, on a sunny day, the prediciton is a bit optimistic. I'll try and explain why I think this.

The plan in the compare suggests the following for tomorrow which is a great generation day:

This is exactly what would make me the most money - however it's not how octopus will run my inverter and battery tomorrow if I was on intelligent flux. From everything I've ready with intelligent flux, octopus tries to do a forced export during the 4pm-7pm peak. It also won't always charge the battery to 100% overnight, depending on the solar forecast. So I think it's a bit like if you configured predbat to maximise self sufficiency, which I'm not doing.

In comparison predbat modelled the day with intelligent flux so that it charged to 100% overnight, then exported maximum solar during the day, then only used the battery to cover house load during the 4pm-7pm peak and didn't do a forced export.

Do you think it's practical to model the intelligent flux comparison on the basis of how octopus are most likely to run the system for a fairer comparison?
