“…Moreover FESS systems have high energy density as well as a high efficiency [4], [5]. In addition, their response time is fast, making it ideal for applications that require a large capacity to be mobilized in a short period of time charge/discharge capacity: high speed, not affected by temperature or deep discharge DoD as with using batteries [6]. On the other hand, the flywheel has a long life that is almost independent of the charge and discharge cycles.…”

Flywheel energy storage systems (FESS) are considered as the grid integration of renewable energy sources due to their buit-in advantages such as fast response, long cycle life and flexibility in providing auxiliary services to the grid, such as frequency regulation, and voltage support. This paper introduces the structure and comparison results of matrix converter and back-to-back converter which integrated with axial flux permanent magnet motor (AFPM) in FESS. Two converters are functionally equivalent in terms of input power quality and energy regeneration capabilities but need to be compared in terms of performance testing with speed response. In this paper, the research results have been verified that matrix converters perform more effective than back-to-back converters.

“…This thesis focus on the PMSM control for energy storage applications, and the DTC and its improvements will be of the interest of this thesis. A dual airgap Axial Flux PM (AFPM) machine prototype for FESS was designed and constructed in the lab by [34]. Figure 1.3 illustrates the main components of the machine and the pictures of the machine assembly can be found in Figure 1.4.…”

“…So far this thesis focus on the rotating direction torque and flux control for the dual air-gap AFPM flywheel motor. The control of the axial direction force was only being addressed by [34] with classical PI control. Special sensor is required to measure the z-axis displacement (for example, Micro-Epsilon Co. DT110-T).…”

Performance improvement of direct torque controlled permanent magnet synchronous motor drives

Permanent Magnet Synchronous Motors (PMSM) have been gaining ever-increasing popularity in many applications thanks to their advantages such as long life, high torque and power density, excellent efficiency, etc. The applications of PMSM could be found in almost every industry such as home appliances, robotics, flywheels, industrial automation, electric vehicles, so on and so forth. Various control methods have been proposed for PMSM to attain satisfying performance with different application needs. For example, V/f control with stabilization loops could be used to control fan-type applications where dynamic response is not a must but efficiency and quietness matter. Field Oriented Control (FOC) is the dominant PMSM control method that achieve good dynamic response, smoothness and energy efficiency.Direct Torque Control (DTC) excels FOC in simpler control structure and supreme dynamic response but suffers from variable switching frequency and severe torque ripples. These defects generally lead to poor torque and flux regulation, high current harmonics and acoustic noise.
