“…10. The basic algorithm for the path protection p‐cycle of PBMP comes from [30], which is modified following the principle described in [34] to cope with the case of dual‐link failure. We found that the CNC of MRBP and MRMS are significantly lower than PBMP.…”

“…Qi proposed an equational path p‐cycle algorithm based on FIPP to protect the dispatching service of EPCN. He took the path length limitation into consideration [30]. Li investigated a p‐cycle based protection scheme with cycle multiplexing and capacity balance to protect the multicast services in EPCN under a single link/node failure scenario [31].…”

For cyber layer, we use the communication network for Jiangsu province power grids in China [8] and two validated communication networks for IEEE 39-bus, 118-bus system, respectively [9], [10]. The size of the networks mentioned above were scaled from 18 nodes to 1225 nodes and the networks contain both IEEE standard test systems and the real systems.…”

Synthetic networks aim at generating realistic projections of real-world networks while concealing the actual system information. This paper proposes a scalable and effective approach based on graph neural networks (GNN) to generate synthetic topologies of Cyber-Physical power Systems (CPS) with realistic network feature distribution. In order to comprehensively capture the characteristics of real CPS networks, we propose a generative model, namely Graph-CPS, based on graph variational autoencoder and graph recurrent neural networks. The method hides the sensitive topological information while maintaining the similar feature distribution of the real networks. We used multiple power and communication networks to prove and assess the effectiveness of the proposed method with experimental results.

“…Literature [20] considers the risks of nodes and links, calculates the shortest path of each service based on the intermediary centrality theorem, and modifies the service route several times to improve the risk balance of the network. In addition, literature [21,22] adopt the P-cycle protection method to configure prefabricated protection routes for important services, which improves resource utilization but reduces the protection ability for a single service.…”

Relay protection service is the most crucial service carried by the electric power communication network, which is directly linked to the safe operation of the power grid. In the route planning of power services, a route planning architecture for the power communication network is constructed in this paper, considering the operation and maintenance requirements, such as relay protection service overload (RPSO) and dual route. To minimize network risk variance, the problem of single-service route allocation is formulated by taking the factors into account such as service delay, link bandwidth utilization, and RPSO constraints. Based on $k$ shortest paths algorithm, a route planning scheme for the power services is proposed, which considers RPSO and risk balance, and a strategy for implementing multi-service route planning of the communication network is studied. The simulation results show that the proposed route planning strategy can effectively avoid relay protection service overload, reduce network risk variance, and balance network risk.
