Special Issue Information

Dear Colleagues,

We are inviting submissions to a Special Issue of Electronics in the subject area of “Optimal Integration of Energy Storage and Conversion in Smart Grids”.

As smart grids continue to evolve, energy storage and conversion play an increasingly important role. Energy storage devices utilize various services, such as peak shaving, power quality improvement, network reliability, short-term energy supply, and improvements in power supply performance, to compensate for the power imbalance between the RES units and loads. In other words, microgrids (MGs) require an energy storage system (ESS) to solve mismatch problems and suit the power system’s requirements. The DC–DC converter (to act as a charger/discharger) associated with the battery in BESS controls the battery voltage and current by performing bucking/boosting operations. In order to coordinate the power-sharing among the heterogeneous energy storage devices spread out over the MG, various control strategies, such as centralized control methods and decentralized control approaches, have been developed for the BES units inside MGs.

Regardless of the significance of ESS technologies used in MG applications, they suffer from some limitations; namely, cost, difficulty of control, limited discharge time, and not being dispatchable without storage.

In addition, due to the intermittent nature of renewable energy resources, microgrid performance fluctuates. The integration of microgrids into the main grid poses a variety of technical and economic issues that may develop when microgrids are integrated into the main network.  All of these issues result in frequency deviation, voltage regulation problems, voltage collapse, large investment, low-power quality, huge transmission loss, and so on.

Novel forms of energy storage and their integration into the grid are the focus of this Special Issue. In addition, the emerging methods/techniques to compensate for the above-mentioned problems, such as frequency deviation, voltage collapse, and low power quality due to the integration of energy storage devices or microgrids into the main grid, will be explored in this Issue.

Submission of multimedia with each article, if possible, is highly appreciated, as it significantly enhances the visibility, downloads, and citations of articles.

Renewable energy sources play a pivotal role in the pursuit of sustainable and eco-friendly power solutions. While offering environmental benefits, they present inherent challenges. Photovoltaic systems rely on surrounding conditions, wind systems contend with variable wind speeds, and fuel cells are both costly and inefficient. Furthermore, the energy injected by renewable energy sources (RES) exhibits unpredictable behavior. To tackle these problems, researchers employ diverse power electronic devices and converters like inverters, power quality filters, and DC–DC choppers. Among these, DC–DC converters stand out for effectively regulating DC voltage and enhancing the efficiency of RESs. The meticulous selection of a suitable DC–DC converter, coupled with the integration of an efficient control technique, significantly influences overall power system performance. This paper introduces a novel approach to the design of switching controllers for DC–DC converters, specifically tailored for application in renewable energy systems. The proposed controller leverages the power of composite switched Lyapunov functions (CSLF) to enhance the efficiency and performance of DC–DC converters, addressing the unique challenges posed by renewable energy sources. Through comprehensive analysis and simulation, this study demonstrates the efficacy of the controller in optimizing power transfer, improving stability, and ensuring reliable operation in diverse renewable energy environments. Moreover, the small-scale DC–DC converter experiment’s findings are presented to confirm and validate the proposed scheme’s practical applicability. Full article
