“…As pointed out in Reference 26, the finite‐time consensus strategy has strong robustness in dealing with communication link failure problems. At the same time, in contrast to the existing the prediction compensation algorithm proposed in dealing with communication faults in References 29 and 31, the previously proposed predictive compensation mechanisms cannot guarantee robust stability when facing parametric uncertainties, unmodeled dynamics, or disturbances. They need relatively complex theoretical models and usually take a long time to achieve system stability.…”

Summary This paper presents a distributed secondary control strategy based on finite‐time consensus protocol for islanded microgrids to ensure the stability of frequency and voltage. Simple droop control cannot achieve high‐precision adjustment due to its inherent shortcomings. Although traditional secondary control can solve this problem, the required conditions are harsh and the system has poor robustness. Based on finite‐time consensus protocol, the proposed distributed secondary control is completely distributed, and agents of network layer only communicate through peer‐to‐peer sparse networks without a central node, so the frequency and voltage remain stable and reach the nominal value within the set time that then improves the system reliability and robustness. Moreover, the improved extreme learning machine, where the empirical risk and structural risk are involved, is used to predict the missing part to deal with the problem of packet loss and communication interruptions. The effectiveness of the intended methods is verified by the simulation of an islanded microgrid.

“…Besides, the coordination between physical inverters is quite dependent on the stable communication link, that is, the interference of the communication layer will lead to system instability 29 . Therefore, the control strategy with certain anti‐interference ability is extremely important in distributed secondary control.…”

The present research investigations in power management fraternity are focused towards the realization of smart microgrid (MG) technologies. Due to intrinsic advantages of Direct Current (DC) system in terms of compatibility with power generation sources, modern loads and storage devices, DC MG has becoming popular over Alternate Current (AC) system. A secondary voltage and current control schemes of DC MG system are mainly based on the distributed consensus control of Multi-agent system (MAS) to balance generation and the demand. The basic concern of the cooperative control of MAS is consensus, which is to design a suitable control law such that the output of all agents can achieve synchronization. The distributed consensus algorithm requires much less computational power and information exchange in between the neighbor's agent. Meanwhile the other controllers such as model predictive control (MPC) requires accurate dynamic models with high computational cost and it suffers from lack of flexibility. The hierarchical consensus control technique is classified into three levels according to their features, namely primary, secondary, and tertiary. MAS is a popular distributed platform to efficiently manage the secondary control level for synchronization and communication among the power converters in autonomous MGs. In this article, various primary control techniques for local voltage control, voltage restoration in the secondary control level and tertiary control for energy management techniques are discussed. With this, the key emphasis to reduce the voltage deviation and disturbances in a heterogeneous DC MG network solutions are discussed. Furthermore, to analyze the system response and the charging and discharging characteristics of the battery unit, the developed second order heterogeneous consensus controller is compared with the traditional homogeneous consensus control and droop control methods. Finally a detailed discussion on simulation case study using heterogeneous consensus control method over the traditional methods are provided using MATLAB/Simulink platform.

“…After estimating the maximum tolerable communication delay based on voltage and power mutation, it uses normal power compensation control for effective operations when communication delay is within the maximum tolerable communication delay, or switches to predictive power compensation control under abnormal communication delay conditions. An accurate prediction is achieved using a double neural network with on-line adjustment of weights and samples[11]. In[12], a new dual redundancy CAN-bus controller is designed based on the field programmable…”

In recent years, automotive manufactures have installed dozens of electronic controller units (ECUs) for various functions related to safety and convenience of drivers. Each ECU controls specific functions of a vehicle, and exchanges information by using the controller area network (CAN). It is characterized by low cost, efficient communication, and high flexibility. In this work, we aim to study the property of CAN bus, and design a new traffic control algorithm to get an excellent CAN system performance. By employing the concepts of two different cooperative game solutions, our approach explores the impact of ECUs' mutual-interaction relationship and devises a novel two-step game model to take the full advantages of CAN resource sharing process. To adaptively handle different data service requirements, control decisions in our two-step game are mutually dependent each other, and each individual ECU acts cooperatively in the proper collaboration manner. This interactive coordinated process continues until a desirable solution is obtained; it is a practical and suitable approach in real world CAN system operations. Finally, simulation testbed is constructed and the numerical analysis is conducted to demonstrate the performance improvement of our proposed method. In addition, several research challenges are discussed and open issues are also outlined. INDEX TERMS Controller area network, electronic controller units, cooperative game theory, minimax regret bargaining, relative benefit equilibrating.
