Abstract: The invention relates to a method for line pressure monitoring, in particular for detecting leaks, in a bidirectionally used line section (40a) of a connection line unit (40) in an energy system (10), in particular in a domestic energy system, as well as an energy system (10) of this type, wherein a first energy source unit (21) and a first energy sink unit (22) are positioned on the first side (43) of the bidirectional line section (40a), and wherein a second energy source unit (31) and a second energy sink unit (32) are positioned on the second side (44) of the bidirectional line section (40a).

Abstract: The present invention relates, inter alia, to a method for storing a medium, in particular a gas, in a pressure storage device (31), wherein, in a preferred embodiment, a dynamic operating pressure, which is dependent on measured temperature values and up to which the medium can be stored in the pressure storage device (31), is determined. In particular, the invention allows dynamic storing of medium in the pressure storage device (31) in respect of the storage pressure, in particular the operating pressure, with a simple design. This is achieved by the dynamic operating pressure being determined, in particular calculated, on the basis of dynamic reference temperature values as a function of time. The method is preferably carried out in an energy system (10), having at least one energy source device (21) for generating a medium and a pressure storage device (31), spatially separated therefrom, for storing the generated medium.
