Speech Title: Low-Carbon Transition and Resilience Evolution of Modern Power Systems under Climate Change
To mitigate climate change, electric power systems are undergoing a rapid low-carbon transition with increasing integration of renewable and other weather-sensitive energy resources. However, the growing dependence of power systems on weather and climate conditions introduces new challenges to secure and resilient electricity supply, particularly under extreme weather events. This presentation provides an overview of the low-carbon transition of modern power systems and discusses the emerging climate risks associated with this transformation. It first introduces the concept of power system resilience and highlights the limitations of conventional reliability-oriented approaches in addressing high-impact extreme events. Recent advances in short-term resilience assessment are then presented, with a focus on integrating meteorological nowcasting, spatial downscaling, and data-driven power system analysis to support rapid assessment under imminent extreme weather. Beyond individual extreme events, the presentation further discusses the evolution of power system resilience under long-term climate change. In particular, long-horizon resilience is introduced as an integrated property emerging from the co-evolution of climate and power systems. Finally, key research prospects are discussed.

Speech Title: Digital twin-based energy management system for solar photovoltaic power and load demand forecasting with economic benefit verification
Accurate forecasting of photovoltaic (PV) generation and electric load is essential for digital-twin-based smart-grid energy management. This study develops an integrated forecasting framework using public meteorological data, task-specific deep-learning models, and adaptive online learning. For PV forecasting, a combination of Pearson correlation coefficient (PCC)-based feature selection, a long short-term memory (LSTM) encoder, and a bidirectional LSTM (BiLSTM) predictor are integrated, reducing hourly and daily forecasting errors by 39.7% and 27.3%, respectively. Online learning further reduces errors by 50.8% in cross-site deployment and 66.9% in long-term deployment, with a maximum single-day improvement of 78%. For load forecasting, a missing-data-aware gated-recurrent-unit with decay mechanism (GRU-D)-temporal convolutional network (TCN)-BiLSTM model incorporates historical loads, missing-data information, meteorological variables, and temporal features. Sparrow search algorithm (SSA)-based optimization reduces training time by 28.71%, while forecasting errors are reduced by 5.13%–29.86% compared with benchmark models. Online learning further achieves error reductions of 15.34% and 60.71% under temporal and cross-region shifts, respectively. Finally, the integrated forecasts are applied to net-load-aware energy management. With 20% controllable load, the monthly electricity cost decreases from USD 69,422 to USD 64,444, saving USD 4,978 (7.17%), while the contracted-capacity exceedance duration is reduced from 49 h to 4 h. These results demonstrate the effectiveness of adaptive PV and load forecasting for practical energy management.
