Özet

The proliferation of distributed energy and concerns about carbon emissions entail a multi-energy enriched coordinated operation in the electrical power system. In this paper, a coordinated stochastic operation between the Transmission System Operator (TSO), renewable sources, energy storage, the hydrogen (H2) energy-equipped Distribution System Operator (DSO), and the Hydrogen System Operator (HSO) is proposed. The stochasticity in the decentralized hierarchical structure is modeled with the IEEE RTS 24-Bus System for the TSO, and 7-Bus and 9-Bus systems for the DSOs, taking into account the uncertainty in renewable energy generation. Furthermore, the HSO participates in the wholesale market as a price maker, and interacts with the DSOs for the lower H2 prices. The total operation cost has been reduced by 33.8% thanks to the Analytical Target Cascading-based distributed AC power flow model. In this context, it is shown that the integrated use of H2 energy and distributed resources under power system coordination can provide remarkable advantages to the transmission, distribution, and H2 gas systems.
