Abstract
This article is the result of a mathematical modeling experiment to insert parameters in the input equations of each system: pumped-storage hydropower plants (PSHP) and solar photovoltaic. The output represents functions regarding the time of production of these sources. When in generation mode, the turbines of the PSHP pour water from a reservoir located at a high altitude, to the lower reservoir, downstream in a river. When in pumping mode, in the need to store energy for later use, which usually happens in times in which the demand for energy is high; energy is consumed from the electrical network to re-establish the volume of water in the upper reservoir, that will act comparatively with charging a battery. It is concluded that this hybrid system can offer stability in demand management and flexibility of operating modes to respond to the intermittency of energy from other sources, as is the case of photovoltaic energy.
