In order to reduce the effect of large distributed generation and impact load connected to distribution network on loss and power quality, and improve the voltage stability and safety of port distribution network, a new Coordinated optimal control strategy based on energy routing structure is proposed. In the upper layer, a multi-objective optimization model with the maximum wind power consumption and netload fluctuation is established. In the lower layer, a multi-objective optimization model with the lowest network loss and the minimum grid voltage quality deviation is established. By taking the energy routing structure as the center of the large power grid and the port distribution network, the power quality control of the grid-connected point is realized by using the current and voltage control strategy of the routing structure, and the optimal allocation of power and energy is realized. Finally, the actual distribution network of a port is simulated as an example, and the simulation results show that the proposed coordinated optimal control strategy can effectively reduce network loss and improve the power quality of the system. © 2022 IEEE.

A finite-time boundedness (FTB) round-robin protocol (RRP) control problem for the 2-D continuous-discrete system described by Roesser model is investigated in the work. Firstly, a novel 2-D RRP is developed to reduce network data congestion and data collisions between controllers and actuators. Under the RRP, a finite-time controller is designed for considered systems. By resorting to the Lyapunov function, deriving finite-time bounded sufficient conditions guarantees that the state is finite-time bounded in a finite-time interval. Finally, the correctness of the proposed result is proved via a simulation example under the RRP in this paper. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

In this work, we address the issue of event-triggered control under the Round-Robin protocol (RRP) for a specific class of 2-D continuous system in Roesser model that is subject to communication constraints. Our approach not only considers network congestion but also takes into account the problem of data collision. To reduce network overloads and save bandwidth, we propose a dynamic event-triggered scheme that determines whether a datum should be transmitted or not. Additionally, RRP is utilized to assign priority to the actuator at a given moment. Sufficient conditions of performance are established to ensure the considered system is stable. Moreover, an event-based control law under the RRP is constructed. The effective of the proposed methods are demonstrated by a numerical example in the end. © 2023 IEEE.

A standalone microgrid plays an important role in supplying power to residential and remote areas by integrating different types of distributed generation. One of the key open issues in both academic and engineering fields is how to provide an optimal planning strategy for distributed generations and storage systems in a standalone microgrid, considering multi-objective performance indices such as reliability and cost. In this paper, a novel constrained multi-objective population extremal optimization (CMOPEO) is proposed for standalone microgrid optimal planning. The fundamental concept of the suggested approach is to frame the problem as a standard constrained multi-objective problem, where power loss probability, fuel emission, and power cost of the system are considered as the objectives, and the maximum amount of extra power and the availability of renewable resources are the constraints. The superiority of the CMOPEO algorithm is demonstrated through simulation results on a standalone microgrid case over multi-objective particle swarm optimization. © Beijing Paike Culture Commu.

The pervasive adoption of Internet-of-Things (IoT) systems has exposed critical vulnerabilities in cyber-security frameworks due to their decentralized deployment in unattended environments. While deep learning-based intrusion detection systems (IDSs) offer promising solutions, the design of hyper-parameters and neural architectures in existing models imposes prohibitive computational costs and expert dependency. To address these limitations, this work proposes an innovative automated hybrid deep learning method for IDS by employing a binary particle swarm optimization (BPSO) algorithm called BPSO-AHDL-IDS to effectively address the intrusion detection tasks of IoT. In BPSO-AHDL-IDS, the combination of convolutional neural network and recurrent neural network is considered as the hybrid deep learning model to extract features of the IoT dataset for accurate detection of intrusions. First, an efficient binary encoding mechanism is developed to describe the hyper-parameters and neural architectures of the hybrid deep learning model. Then, an efficient BPSO-based evolutionary operation is introduced to evolve the hyper-parameters and neural architectures to discover the optimized hybrid deep learning model. The performance of the proposed BPSO-AHDL-IDS method is testified by employing four datasets gathered from different IoT scenarios. It achieves accuracy of 0.9832, 0.9959, and 0.9897, precision of 0.9700, 0.9788, and 0.9843, recall of 0.9724, 0.9822, and 0.965, and F1-score of 0.9712, 0.9804, and 0.9744 on Bot-IoT, ToN-IoT, and Gas Pipeline datasets, respectively. On SWaT dataset, it achieves a precision of 0.9962, a recall of 0.9969, and an F1-score of 0.9965, respectively. The experimental results show the superiority of the proposed BPSO-AHDL-IDS method to machine learning methods, state-of-the-art manually designed and automated deep learning-based IDSs in terms of accuracy, precision, recall, and F1-score. © 2004-2012 IEEE.

Deep neural networks have been widely applied in intrusion detection systems (IDSs), but most of the existing models are designed manually and it is difficult to obtain a lightweight and high-performance model, especially for multi-classification IDS. This work presents an automatic deep learning-based IDS method, i.e., a multi-objective optimization-based transformer for multi-classification intrusion detection of cyber-physical power systems (CPPS), termed MO-Transformer-IDS. This method considers both the architectures such as the number of attention heads in the Transformer-Encoder, the type of activation function, and the number of layers in the Encoder, and the hyperparameters such as the learning rate, batch size, and dropout rate as the decision variables. The two optimization objectives are to minimize the detection error rate and the number of transformer model parameters. The evolutionary operations under the framework of multi-objective differential evolution (MODE) are designed elaborately to search for a Pareto-optimal transformer model. The experimental results on the thirty-seven-classification IDS issue of Power System Attack Datasets have demonstrated that the proposed MO-Transformer-IDS outperforms three state-of-the-art automatic deep learning (ADL) methods including SOPA-GA-CNN, WOA-ANN, GA-CNN, and an advanced LSTM in terms of Accuracy, Precision, Recall, F1-Score, and the number of transformer model parameters. © 2024 IEEE.

The State of Charge (SOC) of lithium batteries can be estimated effectively by particle Filter (PF). However, it is difficult to accurately obtain the value of the parameter discharge current of the lithium battery in the actual process, which affects the accuracy of the PF for SOC estimation. In order to solve the problem, this paper proposes a particle filter based robust state and parameter estimation (PF-RSPE) method for estimating SOC and discharge current of lithium batteries. The method estimates SOC and the unknown parameter discharge current simultaneously. The unknown parameter is expanded to the states of the model. The kernel smoothing method with the fitness factor β is applied in the procedures of the simultaneous estimation, which improves the performance of the estimation. Finally, the proposed method is applied to the equivalent model of Thevenin battery for simulation verification. The results show that when the parameter discharge current is unknown, the PF-RSPE method can effectively estimate both SOC and discharge current. © 2022 IEEE.
