A Reversible Hydropump–Turbine System

Water-pumped storage systems have become an ideal alternative to regulate the intermittent power delivered by renewable energy sources. For small-scale operations, a type of centrifugal pump coupled asynchronous machines represents adequate solution due their techno-economic feasibility in addition ability operate as reversible systems. This work provides novel port-Hamiltonian modelling approach integrated hydropump–turbine system, that can be switched from motor turbine-generator employing conventional hydraulic switch. Our strategy clear physical interpretation flow mechanical electrical domains. Then, model was built with multi-domain storing and dissipating elements interconnection well-defined input–output port pairs. The system’s internal energy, i.e., Hamiltonian function, exploited for energy-shaping control strategies. performance our is validated via numerical simulations.
