“…Eliyan et al. [21] used the PIR of a conventional circuit breaker with three other link technologies to reduce operational overvoltage in wind farms. It was found that PIR and R‐L smart choke successfully reduced the operational overvoltage by an average of 52% in wind farms with radial and star topologies.…”

The pre‐insertion resistors (PIR) within high‐voltage circuit breakers are critical components and warm up by generating Joule heat when an electric current flows through them. Elevated temperature can lead to temporary closure failure and, in severe cases, the rupture of PIR. To accurately predict the temperature of PIR, this study combines finite element simulation techniques with Support Vector Regression (SVR) optimized by an Improved Whale Optimization Algorithm (IWOA) approach. The IWOA includes Tent mapping, a convergence factor based on the sigmoid function, and the Ornstein–Uhlenbeck variation strategy. The IWOA‐SVR model is compared with the SSA‐SVR and WOA‐SVR. The results reveal that the prediction accuracies of the IWOA‐SVR model were 90.2% and 81.5% (above 100°C) in the ± 3°C temperature deviation range and 96.3% and 93.4% (above 100°C) in the ± 4°C temperature deviation range, surpassing the performance of the comparative models. This research demonstrates that the method proposed can realize the online monitoring of the temperature of the PIR, which can effectively prevent thermal faults PIR and provide a basis for the opening and closing of the circuit breaker within a short period.

“…When traffic system utilizes modern wireless communication technologies, which have greatly promoted the development of intelligent transportation system, it could be considered as a cyber-physical system, in which all vehicles communicate via vehicular networking [7]. The applications of CPS in transportation systems could alleviate traffic congestion, and achieve the coordination and intelligence of the traffic system [8]. Since "Cyber" is synonymous with a mixed composition of computation, storage, software, and networking [9], the realization of T-CPS benefits from the development of Vehicular Ad Hoc Network (VANET) technology.…”

In this paper, a cyber‐physical description of mixed traffic that can reflect the interaction between vehicles is first proposed. By treating vehicles as nodes and the cyber‐physical interaction between vehicles as directed edges between nodes, the network of vehicles in traffic is obtained. The small‐world and scale‐free characteristics of mixed traffic are found under this description. Then the CPS‐based pinning approach for achieving indirect control of HVs is proposed. Besides the control algorithm of pinning nodes, the impact of the spatial distribution of automated vehicles on traffic is studied. The approach is compatible with the existing control of automated vehicle in mixed vehicle platoon. Numerical simulation results under three‐lane scenario illustrated the effectiveness of the proposed pinning approach.
