Isolated systems: these are characterised by the fact that neither material nor energy flows can cross the system boundary. Footnote 4. A kettle filled with water is an example of an open system since the heat coming from a stove will penetrate the kettle and the water may leave the kettle as steam. The water circulating in the pipes of a ...

Probabilistic energy flow calculation for regional integrated energy ...

With the increasing coupling among multiple energy systems, component failure of one system may spread to other systems, which results in cross-system failures that will remarkably affect the operation state of RIES. In this regard, this paper proposes a probabilistic energy flow calculation approach for regional integrated energy system (RIES), taking into account those cross-system …

Cross-System Fault Propagation Mechanism in Heat-Electrical …

Heat-electrical integrated energy systems (HE-IES) are gaining popularity due to their high energy efficiency. However, the stronger couplings between sub-energy system increase the risk of cascading faults, limiting the wider application of HE-IES. To address this issue, this paper investigates the fault propagation mechanism between the heating system and power system …

Local smart energy systems and cross-system integration

The three main pillars when designing a future energy system of Varaždin County are the smart energy system concept, i.e. cross-sectoral integration, a self-balanced system and a sustainable use of bioenergy. The latter is particularly important and has not been elaborated much in details in this article. While bioenergy could be a perfect ...
