Hydrological and hydro-energy indicators of the hybrid energy system using solar and pump storage hydroelectric plant

This paper analyses the hybrid solar and pump hydroelectric power plant and its hydrological and hydro energetic characteristics and indicators. The sustainability of the system is based on stable water and energy budget. The key theoretical relationship for solar-hydro system, between electric powers of solar generator, artificial water resources and storage is set, including relevant formulas and indicators. Artificial rain, flow, and hydroenergy potential, as indicators of the hybrid power plant, have been derived, as well as hydroenergy production characteristics. The developed and presented hydrological and hydro energetic indicators are information for hybrid energy system analyses and design. The proposed indicators have been applied on two different climate areas, as paradigms of Continental and Mediterranean climate, using PV and ST generator. The obtained results prove the correctness and usefulness of the proposed indicators for hybrid energy system analysis and development.
