With the increasing integration of wind and photovoltaic energy, source-load uncertainties in active distribution networks have posed new operational challenges. A coordinated multi-resource scheduling approach was proposed, considering energy storage, static var compensator (SVC), capacitor bank (CB), and demand response. A “structure-first, flexibility-second” decision-making framework was adopted. Under this framework, structural decisions such as energy storage commitment and CB switching were first determined to establish a robust system foundation. Then, flexible resources were dynamically adjusted to respond to real-time fluctuations. Uncertainties were modeled using interval and budget constraints to ensure solution robustness. Simulation results on the IEEE 33-bus system show that the proposed method reduces the frequency of structural operations, enhances multi-resource coordination, and improves both economic performance and operational security under uncertainty.
