There are important criteria when identifying flexible consumers. Firstly, the selected systems should not be integrated into production processesin a time-critical manner , as is the case with machines within production lines. Instead, systems from peripheral processes are usually selected. Secondly, a relevant power consumption is also an advantage, whereby load management of many smaller consumers canalso be expedient. These criteria canapply to a wide variety of consumers , which is why identification is always an individual operation-dependent process.
