“…The wind generators belong to this category of energy sources, and to give them the possibility to participate in the ancillary services, a generating system, which is able to feed isolated loads or to be integrated in the network, has to be considered. In order to reach these objectives, an energy buffer is needed for controlling the power flow between the wind generator and the power grid [2]- [9]. In this paper, the energy buffer is represented by a flywheel energy storage system (FESS).…”

Flywheel energy storage systems (FESSs) improve the quality of the electric power delivered by wind generators, and help these generators contributing to the ancillary services. Presently, FESSs containing a flux-oriented controlled induction machine (IM) are mainly considered for this kind of application. The paper proposes the direct torque control (DTC) for an IM-based FESS associated to a variable-speed wind generator, and proves through simulation and experimental results that it could be a better alternative. This DTC application entails two specific aspects: 1) the IM must operate in the flux-weakening region, and 2) it must shift quickly and repeatedly between motoring and generating operation modes. DTC improvement for increasing the FESS efficiency, when it operates at small power values, is discussed. Some aspects concerning the flywheel design and the choice of the filter used in the FESS supervisor are also addressed. Index Terms-DC-linkvoltage regulation, direct torque control (DTC), flywheel energy storage, flux-oriented controlled (FOC), induction machine (IM), power flow supervision, variable-speed wind generator (VSWG).

“…At last, the influence of the rotational inertia and the load torque variation of the proposed control strategy is studied, and an effective load estimation solution is put forward in this paper to solve the instability of the PMSM control system. Kinetic energy is chosen as the control variable in some papers [16] concerning flywheel energy storage applications. Without the load estimation method and the feed-forward control, this control strategy is unsuitable for systems with a variable inertia.…”

A novel vector control strategy for a permanent magnet synchronous motor (PMSM) based on the kinetic energy stored in the rotor is proposed in this paper. The novel strategy is composed of two closed loops, in which the current loop is the inner loop, and the kinetic energy serves as the outer loop. The theoretical basis and the design procedure of the two loops are given. The feasibility of the proposed control strategy is verified by experimental results. When compared with traditional vector control strategies, the proposed vector control strategy based on energy feedback has better dynamic performance. In addition, an effective estimation solution for the load variation is put forward.

“…This paper only studies the latter. The general aim of a energy delivering controller is to control DC voltage and output power to trace the corresponding reference values by adjusting the generator excitation during the decay of rotating speed [8], [9]. When the variation rates of speed and power are not too big, the control aims of synchronous generator systems can be achieved by the feedback controlling of voltage and current [10].…”

Based on an original 12 kW 12-phase synchronous generator system, this paper presents the design scheme and computationally efficient simulation model of a 12-phase flywheel energy storage generator system with linearly dynamic load. In the designed system, the module functions of linearly dynamic load and excitation power amplifier are respectively performed by a Buck converter and full-bridge converter, and a joint algorithm of feedforward and feedback is adopted in the innovative excitation controller module. The system simulation model is built in EMTDC environment, where the machine models are obtained from secondary development in FORTRAN language. The simulation results show that all the designed modules can fulfill their basic functions, the active power of linearly dynamic load increases at the expected rate, the control precision and response speed of the system are satisfactory, and the solution of system simulation model is exact and fast.Index Terms-Excitation controller, excitation power amplifier, flywheel energy storage system, linearly dynamic load, 12-phase generator.
