Special Issue Information

Dear Colleagues,

This Special Issue of Electronics, entitled “Advances in Renewable Energy and Electricity Generation”, seeks to elucidate the significant advancements in renewable energy technologies and their integration into the broader electricity generation ecosystem. This Issue will serve as a repository of pioneering research articles and reviews that highlight innovative methodologies, technological enhancements, systemic optimizations, and emerging concepts. Through this comprehensive exploration, this Special Issue aims to propel the sector towards a more sustainable, resilient, and interconnected energy future.

Central to this discussion is the examination of evolving renewable energy technologies and systems encompassing solar, wind, hydropower, geothermal, and other renewable resources. Concurrently, this Issue will delve into the realm of distributed generation and microgrids, exploring how these decentralized systems can enhance energy accessibility, reliability, and sustainability, especially in remote and underserved regions. Furthermore, we intend to undertake an insightful exploration of the supergrid concept, elucidating the transformative potential of interconnected transmission grids via high-voltage direct current (HVDC) lines. This discussion will encompass operational, technical, and regulatory challenges and opportunities, aiming to foster a deeper understanding of how the integration of renewables can enhance cross-border energy trade, optimize renewable energy utilization, and bolster regional energy security. Additionally, this Issue will also address advancements in grid modernization, energy storage solutions, and intelligent management systems pivotal to harmonizing the integration of renewable energy sources into existing and evolving power infrastructures. This publication will also shed light on the broader implications of these advancements in terms of rural electrification, energy security, and climate change mitigation. By reducing the carbon footprint of the electricity generation sector, these innovations contribute significantly towards global Sustainable Development Goals.

Inviting contributions from academia, industry, and policy circles, this Issue aims to foster a multidisciplinary dialogue to bridge the theoretical and practical divides. We endeavor to showcase high-quality research with the potential to underpin policy formulation, industrial innovation, and academic inquiry in the realm of renewable energy and electricity generation. Through this scholarly endeavor, we aim to spur further research, collaboration, and innovation, edging the global community closer to an energy-secure and sustainable future.

This article proposes a proportional-integral-resonant (PIR) current control strategy for a wind-driven brushless doubly fed generator (WDBDFG) during network unbalance. Firstly, four control objectives of WDBDFG, including eliminating unbalanced currents of power winding (PW), pulsations of control winding (CW) currents, torque, and PW power, are discussed and different from current controls in which the references to PW currents were computed; the CW current references are derived here. Then, an improved CW current controller using a PIR controller is proposed to achieve different control objectives. In contrast with current controls, CW currents are not involved with sequence extraction in the proposed control and can be totally regulated only in a positive synchronous reference frame. Hence, the system control structure is greatly simplified, and dynamic characteristics are improved. Furthermore, in order to obtain completely decoupled control of current and average power, feedforward control, considering all the couplings and perturbances, is also applied in CW current loops. Simulation results for a 2 MW grid-connected WDBDFG show that the proposed control is capable of achieving four control objectives, including canceling CW current distortion, PW current unbalance, pulsations of PW active power or pulsations of reactive power, and machine torque. Its dynamic process is much more smoothly and quickly than that of current controls, and therefore the proposed control has better dynamic control characteristics during network unbalance.

As wind turbine generator systems become more common in the modern power grid, the question of how to adequately protect them from cyber criminals has become a major theme in the development of new control systems. As such, artificial intelligence (AI) and machine learning (ML) algorithms have become major contributors to preventing, detecting, and mitigating cyber-attacks in the power system. In their current state, wind turbine generator systems are woefully unprepared for a coordinated and sophisticated cyber attack. With the implementation of the internet-of-things (IoT) devices in the power control network, cyber risks have increased exponentially. The literature shows the impact analysis and exploring detection techniques for cyber attacks on the wind turbine generator systems; however, almost no work on the mitigation of the adverse effects of cyber attacks on the wind turbine control systems has been reported. To overcome these limitations, this paper proposes implementing an AI-based converter controller, i.e., a multi-agent deep deterministic policy gradient (DDPG) method that can mitigate any adverse effects that communication delays or bad data could have on a grid-connected doubly fed induction generator (DFIG)-based wind turbine generator or wind farm. The performance of the proposed DDPG controller has been compared with that of a variable proportional–integral (VPI) control-based mitigation method. The proposed technique has been simulated and validated utilizing the MATLAB/Simulink software, version R2023A, to demonstrate the effectiveness of the proposed method. Also, the performance of the proposed DDPG method is better than that of the VPI method in mitigating the adverse impacts of cyber attacks on wind generator systems, which is validated by the plots and the root mean square error table found in the results section.
