Pumped energy storage project case

What is pumped hydro energy storage (PHES)?

Pumped hydro energy storage (PHES), of many bulk-EES technologies, generates electricity at the peak load demand by utilizing stored water during an off-peak period in the upper reservoir [2, 3], thereby swiftly managing the intense load and frequency change without significant changes in voltage [1, 4].

What is a pumped storage system (PHES)?

PHES can be integrated with intermittent renewable energy sources such as wind energy and solar photovoltaic plants for the continuous supply of electricity. In comparison to traditional energy generation methods, the hybrid solar and pumped storage system is more eco-friendly [8, 9, 10] and financially viable technology .

How pumped storage can be integrated with a solar power plant?

By integrating the small-scale pumped storage with the solar power plant, the system operation became more flexible because the power generation could be scheduled and optimized easily. The scheduling of the solar-pumped storage system was done using Python software. The pumping and generation schedule of pumped storage is shown in Fig. 6.

Can small-scale pumped-storage be used for energy storage?

It was found from these interviews that an interest exists in systems for energy storage by small-scale pumped-storage. The main usage of this new storage would be in mitigating the power peak resulting from the start of the industry or from human activity.

Can hybrid solar and pumped hydro storage system fulfill load demand?

A pumped storage hydro system is a viable, large-scale resource that is being utilized today for storing energy. The study aims to design a hybrid solar and pumped hydro storage system to fulfill the increased load demand for 10 years in Pauri Garhwal (Uttarakhand, India).

How to study a small pumped-storage power plant?

To facilitate the study of a small pumped-storage power plant, an in-house software program was developed using Python 3.7 and the PySimpleGUI library (version 4.18.2). The results presented in the next section were obtained using this program. The different cost models were developed based on the literature or quotes obtained from suppliers. 3.
