Abstract
To improve the economic performance of such hybrid power plants in the electricity-hydrogen coupled market, an in-depth study is conducted on the scheduling and trading strategies of hybrid power plants participating in the day-ahead market. First, a two-stage optimal operation framework based on a dual-settlement mechanism is established, and stochastic optimization methods are employed to effectively handle uncertainties in hybrid power plants. Second, a piecewise linearization technique is adopted to fit the hydrogen production efficiency curve, enabling optimal efficiency scheduling of electrolyzers. In addition, a coordinated operation strategy for multiple electrolyzers is designed to effectively extend the service life of the electrolyzers. Finally, simulation case studies demonstrate that the proposed model can effectively achieve coordinated regulation and optimal operation of renewable electricity trading and hydrogen production through the coupled optimization of energy storage systems and electrolyzers, thereby verifying the effectiveness and rationality of the model.
