Volt-VAR-Pressure Optimization of Integrated Energy Systems With Hydrogen Injection

Volt-VAR optimization (VVO) has been investigated extensively in power systems. However, under the era of integrated energy systems (IES), growing interdependencies between different complicate traditional VVO. This is further hardened by incurred gas quality problems due to hydrogen injection IES, produced widely applied power-to-gas (P2G) facilitates that couple and paper develops a two-stage volt-VAR-pressure (VVPO) model for PV-penetrated IES manage variation system voltages while managing indices. In addition voltage regulating devices, P2G facilities, which can mitigate fluctuating PV output via converting surplus generation into hydrogen, are also used management. A distributionally robust (DRO) based on moment information utilized uncertainty. semidefinite programming formulated finally solved constraint algorithm. 33-bus-20-node verify effectiveness proposed VVPO management, ensured with high economic efficiency. The applicable injecting other green gases ensuring enable operators provide low-cost but high-quality multi-energy customers.
