Special Issue Information

Dear Colleagues,

Smart grids are crucial components of future intelligent power distribution systems, significantly contributing to energy savings, emission reductions, and sustainable development. As an effective means of integrating distributed power generation into the grid, the diverse control methods and high permeability of power electronic interface micro-sources pose significant challenges to microgrids' safe and stable operation. Therefore, this Special Issue invites articles addressing the technical challenges in stability analyses and control, presenting new findings and innovative technologies to enhance smart grids’ operation, control, protection, and security, ultimately facilitating the transition to sustainable smart cities.

Overall, the stability analysis and control of smart grids have played a vital role in shaping the future of electrical systems and are critical to achieving a more sustainable and energy-efficient world.

The scope of "Stability Analysis and Control of Smart Grids" encompasses various aspects of microgrids. It covers advancements in technology and methods that enable the development of more efficient, reliable, and cost-effective microgrids. Topics include but are not limited to the following:

  • Renewable energies applied in microgrids;
  • Power converters in microgrids, such as DC–DC converters, AC–DC converters, and DC–AC converters;
  • Development of advanced control techniques, including nonlinear theory, artificial intelligence, and model predictive control;
  • Development of structures and topologies for microgrids;
  • Potential stability issues and destabilization for microgrids;
  • Cyber security risk of microgrids;
  • Communication methods for microgrids;
  • Development of more efficient, reliable, and cost-effective electrical systems.

In this paper, we perform a threat modeling of architectures for controlling the medium voltage (MV) part of the power grid, arguing the importance of this topic with a brief summary of serious cyber security attacks from the last decade. As more Distributed Energy Resources (DERs) are introduced into this part of the grid, the need to control these resources arises. A threat modeling of two alternative control architectures is performed to study two different aspects. Firstly, we study and compare the cyber security of the two architectures to determine whether one of them is inherently more secure than the other. While both architectures rely on 5G, one of the architectures uses a centralized design, while the other uses a distributed design. Our results indicate that at the current level of detail, contrary to common belief, it is difficult to draw definitive conclusions as to which architecture is more secure. The second aspect we study is the applied threat modeling method itself. We evaluate and test the method and suggest improvements. Full article

In recent years, step-up/step-down DC–DC converters have been required in renewable energy processing and energy storage applications. In the latter, lithium-ion batteries have played an important role since they have been the most usable source in portable equipment and electric vehicles. This paper proposes a novel step-up/step-down converter with continuous input current and a model-based control scheme. Moreover, the converter design highlights based on steady-state analysis are obtained for a proper parameter selection of the converter. Thus, a fourth-order average system model is obtained to design a multiloop control law. The proposed control is designed in such a way that the control scheme results in an inner current loop on the input current and an outer control loop on the output voltage. Finally, experimental results are performed to assess the performance of the proposed power converter and the control law. An experimental setup with an efficiency of 95 % is implemented to validate the theoretical analysis. The intended application is to regulate a voltage fluctuation from 200 V to 250 V to a constant voltage of 200 V with a nominal power of 533 W. Full article
