Energy Storage Flywheel Rotors—Mechanical Design

Energy storage flywheel systems are mechanical devices that typically utilize an electrical machine (motor/generator unit) to convert electrical energy in mechanical energy and vice versa. Energy is stored in a fast-rotating mass known as the flywheel rotor. The rotor is subject to high centripetal forces requiring careful design, analysis, and fabrication to …

DC Circuit Breaker Evolution, Design, and Analysis

An overview of a typical DC MG is presented in Figure 1. DC circuit breakers are placed at various locations in the grid, near the renewable energy resources, transmission line, main grid, battery bank, and load sides to ensure microgrid protection and mainte-nance. The DC circuit breaker (CB) types vary due to the presence of different …
