Can fuzzy logic control a hydraulic gravity energy storage system?

Relying on the review and to the best of our knowledge, the development of a Fuzzy logic control for the hydraulic gravity energy storage system (HGESS) has never been documented in the literature. Moreover, the investigation of the best combination of system dimensions using Fuzzy logic is a novel contribution.

How to dimension gravity energy storage system?

A novel approach for dimensioning gravity energy storage system is implemented. Fuzzy logic controller is developed for considering the input power uncertainty. Centroid defuzzification and Gaussian membership function are the most suitable. Design dimensions are identified for the large, medium, and small power plants.

How MATLAB-Simulink simulates a physical energy storage system?

The modeling step starts with the mathematical formulation of the system. In which the governing equations for each part of the physical energy storage system are driven depending on the energy required. These equations are used to simulate the true system using the virtual simulation tools of MATLAB-Simulink.

What is considered a gravity hydro-storage system?

The considered system is a gravity hydro-storage system. The proposed dimensioning methodology relies mainly on three techniques: the mathematical modeling of the system, a proposed simulation model, and a developed Fuzzy logic control system. The investigation considered two uncertain inputs: the energy and its rate of change.

What are the design parameters of gravity storage system?

The gravity storage system was categorized into four scales of power plants. As specified before, the gravity storage system under study has five design parameters, namely, container height (Hc), piston height (Hp), piston diameter (Dp), return pipe length (Lp) and return pipe diameter (dp).

Can abandoned mine shafts be used to build a gravity energy storage system?

Morstyn et al. proposed to use the abandoned mine shafts to build a dry model of the gravity energy storage system. The suspended weight is used to store energy via its movement on the mine shaft.
