Gravity energy storage offers a viable solution for high-capacity, long-duration, and economical energy storage. Modular gravity energy storage (M-GES) represents a promising branch of this technology; however, the lack of research on unit capacity configuration hinders its widespread adoption.
The actual use of multiple basic units does not change the shape of the surface, so the following analysis is general. Combined with the actual engineering situation, the unit capacity of a gravity energy storage power plant is generally not less than 100 kW level.
Literature established a power control method for modular gravity energy storage (M-GES) plants to mitigate power dips by introducing dead zones for stable output. However, as plant scale increases, the number of required units rises, potentially leading to unit congestion, a unique issue in M-GES plants with dead zone control.
