Abstract
This article presents the design of a gravitational potential energy storage system for storing electrical energy from renewable power generation systems. The system incorporates a balanced double-arm ‘A’-frame tower crane along with a layered weight array to enhance energy density. It utilizes a permanent magnet stepper motor (NEMA23) as the main hoist motor. The design calculation is based on an energy storage capacity of 1 Wh, utilizing a total mass of approximately 46.8 kg per layer over seven layers (total 327.6 kg) with automated control. The novelty lies in the compact, modular design, offering geographic flexibility compared to pumped hydro systems. This design aims to improve the stability of electrical energy from renewable power generation systems, reduce excess energy losses, and enhance the potential for future practical applications.
