During this process, generative artificial intelligence (GAI) plays a critical role in education and research activities. However, GAI's impact on smart energy systems research and education is less discussed. Especially, its impact on education is rarely discussed when compared to research. GAI reshapes both the research process and the roles of teachers and students in the course. This perspective offers insights into the ongoing research and education paradigm shifts observed in the smart energy system. This perspective synthesizes existing studies on \"GAI for Science\" and \"GAI for Education\" practices in the field of smart energy systems. In research, the impact of GAI is discussed from both macro and micro levels. In education, this perspective examines how a GAI-driven teaching approach addresses the challenges of teaching smart energy systems compared to the traditional approach.

An efficient anode pressure control strategy is imperative for enhancing the overall system efficiency and mitigating lifespan degradation. Effective anode pressure control can prevent hydrogen starvation and instability in output performance under rapid load changes and purge disturbances. Fuzzy control has been extensively employed in anode pressure control studies. However, creating fuzzy rules in the control parameter’s tuning process in existing studies is predominantly dependent on expert knowledge, resulting in concerns about control accuracy. This study investigates the potential of employing the whale optimization algorithm to optimize the selection of fuzzy parameters. We first developed a control-oriented model to address the nonlinearity, coupling, and uncertainty in the hydrogen supply system. Then, based on the model and considering load variations and purge disturbances, we integrated feedforward compensation and fuzzy control into the conventional Proportional-Integral (PI) controller to suppress input disturbances, enhance control accuracy, and reduce the pressure response lag. Finally, an innovative fuzzy PI controller with the whale optimization algorithm is proposed to optimize the fuzzy parameter selection, thereby achieving precise anode pressure control. Simulation tests demonstrate that the whale-optimization-based fuzzy PI control (WFLPIF) reduces a root mean square error by 14.3 % (0.636 vs. 0.742) and a mean absolute percentage error by 28.8 % (0.037 vs. 0.052) compared to conventional PI control, while also outperforming feedforward-compensated fuzzy PI control (FLPIF) by 9.5 % in RMSE and 17.8 % in MAPE.

This paper proposes a dynamic charging duration prediction framework for EVs, composed of four coordinated modules: data preprocessing, charging pattern classification, static prediction, and dynamic bias correction. First, raw charging data collected from the Battery Management System (BMS) is cleaned and normalized to address missing and abnormal values. An enhanced convolutional autoencoder (EV-CAE) is then employed to extract multi-scale temporal features, while K-Means clustering is used to identify representative charging behavior patterns. Based on the classified patterns, the static prediction module estimates the current charging duration by leveraging historical data and pattern labels. To enhance adaptability under dynamic conditions, a bias correction mechanism is designed, integrating linear, logarithmic, proportional, and deep learning-based strategies to adjust the prediction results in real time. Experimental results on real-world EV datasets demonstrate that the proposed framework significantly improves prediction accuracy. In particular, the dynamic correction module increases the coefficient of determination (R²) from 0.948 to 0.960, while maintaining robust performance under fluctuating charging behavior and low-temperature conditions.

Traditional drainage strategies rely on experience and trial-and-error methods, making it difficult to adapt to complex and dynamic production environments. This study proposes a life-cycle production and drainage optimization strategy for CBM based on Deep Reinforcement Learning (DRL). Utilizing the Deep Q-Network (DQN) algorithm, this work learns and optimizes the drainage strategy during the production process, achieving intelligent decision-making for drainage operations. An auto-regressive surrogate model is introduced to build a reinforcement learning environment for gas production and drainage, based on a deep learning model (CNN-LSTM). This model substitutes the full-physics simulation model that requires high computational cost, significantly accelerating the interactive learning process between the agent and the environment in DRL. Whether to set the gas production or Net Present Value (NPV) as reward, two strategies for reinforcement learning were considered accordingly. The results concluded that the DRL drainage strategy with NPV as the reward increased the net gain by 5.83 % compared to historical data. Compared with traditional methods, this approach significantly improves the NPV and optimizes the drainage strategy. The findings demonstrate that the life-cycle drainage optimization method for CBM based on DRL is not only efficient and feasible but also provides an intelligent solution for the development of unconventional natural gas resources.

Also, these analyses depend on flaring and methane leakage datasets, which should ideally be updated in near real-time, challenging to integrate effectively to process models.
