A Lab-scale Flywheel Energy Storage System: Control Strategy and Domestic Applications

Abstract

Flywheel is a promising energy storage system for domestic application, uninterruptible power supply, traction applications, electric vehicle charging stations, and even for smart grids. In fact, recent developments in materials, electrical machines, power electronics, magnetic bearings, and microprocessors offer the possibility to consider flywheels as a competitive option for electric energy storage, which can be of great interest for domestic applications in the near future. In this paper, a grid-tied flywheel-based energy storage system (FESS) for domestic application is investigated with special focus on the associated power electronics control and energy management. In particular, the overall PMSM-based flywheel configuration is reviewed and a controlling strategy was experimentally implemented using DS1104 controller board from dSPACE. Two case studies were considered for power peak shaving and power backup at domestic level. A lab-scale prototype was built to validate the proposal. The achieved results are presented and discussed to demonstrate the possibilities offered by such an energy storage system for domestic application.

Control Strategy of Flywheel Energy Storage System Based on Primary Frequency Modulation of Wind Power

“…With the FESS in the power compensation phase, the control strategy of the power outer and current inner loops was used to perform real-time peak shaving for the power curve output by a wind turbine. When wind power is too great, the FESS uses the excess power to charge up; contrarily, the FESS compensates for fluctuating and/or extremely low wind power by discharging power more smoothly to the grid [21][22][23][24][25]. The FESS flow chart for the real-time compensation of wind power output by a wind turbine is shown in Figure 4.…”

Critical Review of Flywheel Energy Storage System

“…Similarly, in terms of residential application, the production of a domestic FESS may help to establish a low-carbon future. The excess energy produced by other renewables can be stored and released on-demand, with guaranteed wear and tear over 25 years and an efficiency of 90% [136,137].…”
