Abstract: Various embodiments of the teachings herein include a computer-assisted energy management method for an energy system, in which an operation of the energy system is regularly simulated according to a set call time interval for a set time horizon with a set time increment, comprising: determining whether a first parameter changes; performing an additional simulation of the operation of the energy system deviating from the set call interval based on the changed parameter; and/or within at least one critical time range in which a value of the first parameter is above a threshold value, performing a regular simulation which falls within the critical time range with a time increment which is smaller or greater than the set time increment; an operating the energy system according to either the additional simulation or the regular simulation.

Abstract: A method for monitoring an energy feed-in point of an energy supply network is particularly suited for low voltage systems. A number of first and second nodes a producer, consumer, or prosumer—are connected to the feed-in point. An actual current representing the current consumption or current output is detected at the feed-in point by a measuring and monitoring device. An item of current information received from a first node, representing an intended and/or maximum possible current consumption or output of the first node, is processed by checking whether a current value thereof fulfills a predetermined criterion relative to a possible current value of the feed-in point. The possible current value is a differential between the predetermined maximum current and the actual current. Depending on whether the criterion is fulfilled, a message is transmitted confirming or denying the current consumption or output to the first node.
