POWER_BALANCE_CALC
Real-time microgrid power balance with signed battery flow, net load and metering-residual supervision.
When to use it
Use POWER_BALANCE_CALC when a microgrid has metering on its generation, its load and its utility tie, and the dispatcher, the frequency controller or the reporting layer needs the balance and the residual between them.

Create a free Ri Tech account to download the block. You get the Structured Text body, the Rockwell Add-On Instruction (.L5X), the Schneider Control Expert DFB (.XDB), PLCopen XML, the IEC 61499 function block type (.fbt) and the datasheet.
Every block in the catalogue is free to download, in every format, with no purchase and no card. Browsing needs no account at all; downloading needs a signed-in one, so the block lands in your library and re-downloads whenever you need it.
Source is never published on this page. The implementation is released to a signed-in Ri Tech account — free of charge, but never anonymously.
