Frost Heave Evolution and Thermo-Hydro-Mechanical Coupling Analysis of Transmission Tower Foundations in Silty Clay of Seasonally Frozen Regions

Frost heave of transmission tower foundations in seasonally frozen regions endangers cold-region power infrastructure and grid security. This study establishes a coupled model to simulate foundation freeze-thaw and frost heave processes, validated via laboratory tests. The result...

Weather-guided decomposition and hard-routing expert modeling for short-term photovoltaic power forecasting

Solar energy has become a pivotal renewable resource in modern power systems; however, the stochastic and weather-dependent variability of photovoltaic (PV) generation continues to challenge accurate power forecasting and grid operation. This study proposes a weather-adaptive for...

Multi-Time-Scale Distributed Voltage Optimization for AC/DC Hybrid Distribution Networks with High-Penetration Photovoltaics

After high-penetration distributed photovoltaics (DPVs) are integrated into AC/DC hybrid distribution networks, stochastic source-load fluctuations, AC-DC coupling, and heterogeneous response characteristics of voltage-regulation devices jointly aggravate voltage violations and r...
