Abstract

The present invention relates to a control system for a hybrid system comprising at least one energy store (1) and an energy source (2), the control system using a charge state (Z) in the at least one energy store (1), a nominal operating point (P11) of the energy source (2) and a system power (P1) which is currently to be output to ascertain a storage power (P3) which is to be output or received by the at least one energy store (1) and a source power (P2) which is to be output by the energy source (2) on the basis of at least one optimization criterion. In order to create a particularly flexible control system, the invention provides that at least one charge limit value (P4, P7, P8) and at least one discharge limit value (P5, P9, P10) for the at least one energy store (1) and a power limit value (P12) for the energy source (2) are also used at the same time in order to ascertain the storage power (P3) and the source power (P2), and that the at least one charge limit value (P4, P7, P8), the at least one discharge limit value (P5, P9, P10), the power limit value (P12) and the nominal operating point (P11) can be parameterized via an interface (5) in the control system.
