Special Issue Information

Dear Colleagues,

As concerns about climate change, resource depletion, and environmental degradation continue to grow, the need for green sustainable energy becomes more urgent than ever. Green energy refers to the production of energy using environmentally friendly methods that minimize negative impacts on the planet. Power generation systems play a crucial role in transitioning to a greener future as they harness renewable energy sources, reduce greenhouse gas emissions, and foster sustainable development. Hence, power generation systems have been studied in depth for green sustainable energy, such as: solar energy systems, wind energy systems, hydropower systems, biomass energy systems, geothermal energy systems, and tidal and wave energy systems. Each of these power generation systems offers unique advantages in the pursuit of green sustainable energy. By diversifying our energy portfolio, investing in research and development, and embracing innovative technologies, we can work towards a more sustainable future where our energy needs are met without compromising the health of our planet. Through this Special Issue, we hope to summarize the current research on power generation systems for green sustainable energy and explore the application of advanced materials, information technology, etc., in the systems.

This Special Issue will focus on novel power generation systems, advanced materials, optimization techniques, and emerging trends in renewable energy technologies, as well as policy implications and challenges associated with the transition to a green energy future.

In order to reduce the negative impact of the large-scale grid connection of residential photovoltaic (PV) equipment on the distribution network, it is of great significance to realize the real-time accurate identification of the grid connection state and its switching of residential PV equipment from the distribution network side. This paper introduces a non-intrusive method for identifying residential PV systems using transient features, leveraging the temporal convolutional network (TCN) model with attention mechanisms. Firstly, the discrimination and redundancy of transient features for residential PV devices are measured using a feature selection method based on the semi-Fisher score and maximal information coefficient (MIC). This enables the construction of a subset of identification features that best characterize the PV devices. Subsequently, a sliding window two-sided cumulative sum (CUSUM) event detection algorithm, incorporating a time threshold, is proposed for the real-time capturing of PV state switching and grid connection behavioral events. This algorithm effectively filters out disturbances caused by the on/off cycles of low-power residential devices and captures the transient time windows of PV behaviors accurately. On this basis, a TCN model with attention mechanisms is proposed to match the discerned event features by assigning varying weights to different types of characteristics, thereby facilitating the precise recognition of a PV grid connection and state-switching events. Finally, the proposed method is validated on a custom-designed non-intrusive experimental platform, demonstrating its precision and real-time efficiency in practical applications. Full article

With the increasing integration of renewable energy into the power grid, there is a growing demand for converters that not only provide stable power, but also support auxiliary functions such as grid-voltage regulation. Consequently, grid-forming strategies have attracted significant attention. However, due to the complexities of analyzing nonlinear coupling systems, a comprehensive transient stability analysis of grid-forming converters is still being explored. Conventional analysis methods rely on a simplified quasi-steady-state model for grid-forming voltage source converters (VSCs) and focus on analyzing the transient instability phenomenon caused by the outer power loop. However, this oversimplified model may yield incorrect conclusions. To address this limitation, this paper develops a full-order model that includes quadratic nonlinear terms to accurately represent the system’s nonlinear characteristics. The developed model is then decoupled into multiple low-order modes using a nonlinear decoupling method. These low-order modes can be analyzed using the mature inversing trajectory method, indirectly reflecting the transient stability of grid-forming VSCs under large disturbances. Through varying the inner and outer parameters, the transient stability of grid-forming VSCs is analyzed in detail. Furthermore, the analysis results are verified through hardware-in-loop (HIL) experiments. Full article
