Introduction: Renewable energy sources majorly contribute to power generation for the past few years due to the rising population and economic and technological development. In renewable energy sources especially solar, the primary challenge is their intermittent nature. To overcome this limitation energy storage systems are required. Typically, the battery is the most common form of energy storage for home appliances solar systems. Which is expensive, less environmentally friendly, required frequent maintenance, and short lifetime. Therefore, the pumped storage system is suggested for large-scale standalone appliances. It is a process of converting electrical energy into potential energy by pumping water to the upper reservoir and then released through hydraulic turbines to generate electrical energy.

Methods and Results: This paper presents the PSCAD system model of the solar with pumped storage system to achieve higher utilization of solar by pumping water to the upper reservoir to store the energy when power generation is higher than demand whereas the stored water is released back to the lower reservoir through a turbine to generate electrical energy when power generation is lower than demand.  The overall system includes a PV module, Upper reservoir, Lower reservoir, Pump, Generator, and Three-phase inverter. The optimum design of the model is determined by the pump and generator capacities, upper reservoir volume, and lower reservoir volume.

Conclusions: In this paper, the simulation results indicate that a pumped storage system has a higher possibility to be a large-scale energy storage system and well suited for standalone applications.
