Special Issue Information

Dear Colleagues,

There has been a paradigm shift in energy production and distribution after the emergence of the Internet of Things (IoT). The IoT is now used in all areas of renewable energy production, i.e., generation and transmission, as well as distribution equipment. These devices enable monitoring and controlling the operation of equipment remotely in real time. This reduces operational costs and lowers dependence on already-limited fossil fuels.

The use of renewable energy resources already provides a variety of benefits over conventional ones. The implementation of IoT will help to utilize these clean energy sources further.

Although the use of IoT in renewable energy management provides many benefits, it is not without its challenges and obstacles. The challenge with utilizing IoT devices is their vulnerability to hacking. Since devices are connected to a network, a cyberattack could occur if the network is not secured properly. This can lead to hazardous and unfavorable conditions.

This Special Issue covers IoT applications for renewable energy management and control, as well as its security aspects and associated issues and challenges.

Suggested Topics:

  • IoT application in smart grid energy management;
  • IoT application in renewable power generation;
  • Forecasting demand with IoT;
  • IoT application in power distribution;
  • IoT application in power grid automation;
  • IoT application in domestic power;
  • Security of IoT networks;
  • Advanced technology of electrical engineering.

Different locations and types of faults affect the safe and reliable operation of DC microgrids. Therefore, this paper proposes a secondary multiple fault-tolerant control scheme for a DC microgrid based on a sliding mode observer to ensure the voltage is restored to the rated value and realize the proportional current sharing of all sources. Firstly, the secondary control model of the DC microgrid is established, considering the multiple faults of actuators and sensors simultaneously. Secondly, the system model is transformed into two subsystems by bilinear coordinate transformation, and multiple faults decoupling between the sensor and actuator is realized. Then, two sliding mode observers are designed for the two transformed subsystems. The sliding mode variable structure equivalent principle is used to reconstruct the faults at different positions without knowing the fault models in advance, which is convenient for subsequent processing. Then, the fault-tolerant controller based on the sliding mode observer is designed, which uses the reconstructed value to offset the influence of sensor and actuator faults on the DC microgrid and realizes the fault-tolerant control of the DC microgrid. Finally, the effectiveness of the proposed control strategy is verified by experiments. Full article

Conventional droop control (a decentralized method to regulate power sharing by adjusting voltage–current slopes) in DC microgrids faces challenges in balancing precise current distribution, bus voltage regulation, and communication pressure, especially in distributed energy management scenarios. To address these limitations, this paper proposes an adaptive control strategy combining three layers: (1) Primary control achieves power sharing and voltage stabilization via U-I droop characteristics for distributed energy resources (DERs); (2) Secondary control corrects voltage deviations and droop coefficient imbalances through multi-agent consensus algorithms, ensuring global equilibrium; (3) Event-triggered consensus control minimizes communication pressure via a novel protocol with time-varying coupling weights and a hybrid trigger function combining state variables and time-decaying terms rigorously proven to exclude Zeno behavior (i.e., infinite triggering in finite time) using Lyapunov stability theory.
