CONTROLLER FOR ENERGY SUPPLY SYSTEMS

摘要

The present invention relates to energy supply systems which comprise an energy storage unit and an energy production unit. Control methods according to the invention advantageously allow to calculate an operational cost of the energy supply system based on the energy flux that can be supplied by the system and the energy flux that is demanded externally from the system. The operational cost can be calculated for all possible values of the above parameters in advance. The calculated parameters can be stored in an array in a device implementing methods of the invention. Methods of the invention allow to operate an energy supply system so as to guarantee that at any instant a predetermined (nonzero) amount of energy flux can be supplied by the energy storage unit.
