Two-Stage Distributionally Robust Optimization for Secure Operation of Provincial Power Grids with High Renewable Penetration

Provincial power grids with high wind and photovoltaic penetration face poor out-of-sample security under limited data, whereas robust scheduling can be overly conservative. This study develops an integrated scheduling framework for secure provincial-grid operation using established two-stage Wasserstein distributional...

A Spatiotemporal-Awareness MARL Voltage Regulation Method for Distribution Networks with High Penetration Ratios

To tackle frequent voltage violations in distribution networks with high photovoltaic penetration ratios, voltage regulation methods that dispatch the active and reactive powers of PV panels are widely studied. Because of the costly global communication networks, in current distributed voltage regulation methods based...
