Multi‐scale coordinated optimal dispatch method of electricity‐thermal‐hydrogen integrated energy systems

To achieve carbon neutrality, renewable energy-based power systems and hydrogen are increasingly being promoted. A novel electricity-thermal-hydrogen integrated energy system that combines new generation, multi-source load, multiple storage is proposed by the authors. address uncertainties in output, issues of untimely unit regulation response large planning tracking errors, a multi-scale scheduling method based on model predictive control (MPC) was proposed. In day-ahead dispatching stage, an optimal economic established with lowest operation cost as optimisation objective. The considers equipment investment, operation, maintenance, peak-to-valley differences electricity prices. intraday MPC-based rolling correction strategy to cope contact line fluctuations caused prediction errors load. This time-domain feedback real-time state eliminate influence uncertainty factors microgrid. form discrete space transformed into quadratic problem improve efficiency accuracy solution. Finally, typical microgrid used example verify effectiveness method. Results show error can be within 0.025 kW, single time 0.14 s.
