Economic-Effective Multi-Energy Management Considering Voltage Regulation Networked With Energy Hubs

This paper develops a novel two-stage coordinated volt-pressure optimization (VPO) for integrated energy systems (IES) networked with hubs considering renewable sources. The promising power-to-gas (P2G) facilities are used improving the interdependency of IES. proposed VPO contains traditional volt-VAR functionality to mitigate voltage deviation while ensuring satisfying gas quality due hydrogen mixture. In addition conventional regulating devices, i.e., on-load tap changers and capacitor banks, P2G converter storage address fluctuation problem caused by penetration. Moreover, an effective distributionally robust (DRO) based on Wasserstein metric is utilized capture uncertainty tractable counterpart reformulations. Wasserstein-metric ambiguity set enables provide additional flexibility hedging against uncertainty. Extensive case studies conducted in modified IEEE 33-bus system connected 20-node system. provides voltage-regulated economic operation scheme ensured that contributes high-quality but low-cost multi-energy supply customers.
