"Prosumer" Electrical Installation that is - i.e. an installation that can both produce and consume electricity.
I've been looking over the new Part 8.
It seems to describe quite a sophisticated setup - a "smart" system if you like - dynamically changing things according to some pre-programmed algorithms - maybe to minimise imports, perhaps to export 'when the price is right', deciding whether storage (if present) should accumulate or release, or something else. There even seems to be a specific requirement that a PEI incorporate an 'Electrical Energy Management System' (EEMS) (822.4).
Which got me thinking - how does a conventional ("dumb") grid-tied PV system fit into this? - where the amount of power generated locally is uncontrolled (i.e. just depends on external variables such as sunlight) and the only "management" is what can be achieved using a length of copper and Ohm's Law (i.e. any surplus just gets exported).
Is the idea that such installations should be smarter in future, or is it just that the non-existent management system of a typical PV system can just scrape through as a 'minimal' EEMS?
