Texto completoThe increasing focus on large scale integration of new renewable energy sources like wind power and wave power introduces the need for energy storage. Superconducting Magnetic Energy Storage (SMES) is a promising alternative for active power compensation. Having high efficiency, very fast response time and high power capability it is ideal for levelling fast fluctuations. This thesis investigates the feasibility of a current source converter as a power conditioning system for SMES applications. The current source converter is compared with the voltage source converter solution from the project thesis. A control system is developed for the converter. The modulation technique is also investigated. The SMES is connected in shunt with an induction generator, and is facing a stiff network. The objective of the SMES is to compensate for power fluctuations from the induction generator due to variations in wind speed. The converter is controlled by a PI-regulator and a current compensation technique deduced from abc-theory. Simulations on the system are carried out using the software PSIM. The simulations have proved that the SMES works as both an active and reactive power compensator and smoothes power delivery to the grid. The converter does however not seem like an optimum solution at the moment. High harmonic distortion of the output currents is the main reason for this. However this system might be interesting for low power applications like wave power. I

Texto completoMagnetic energy is stored when a superconducting inductance is fed with current. This principle is called SMES (Superconducting Magnetic Energy Storage). This kind of device has a relatively low energy density but can have a high power density. This PhD work has been conducted in the frame of the BOSSE project with the objective to develop a SMES demonstrator in the MJ range. This SMES will be especially compact and will reach a specific energy of 20 kJ/kg of winding, which is 50 % over the current world record for a superconducting coil. This performance is made possible by the use of 2nd generation high critical temperature superconductors, so-called “REBCO” conductors.This work tackles the general problematic of SMES design and proposes elements of reflection and solutions for fast pre-design of a SMES winding. The design of the high specific energy SMES of the BOSSE project is presented in detail.Modular elements (pancakes of REBCO tapes) of the SMES have been manufactured and tested in self-field and under background magnetic field. During these tests, transitions from superconducting state to normal state have been detected. These early detections have prevented the pancakes to be damaged when transitions occurred, even at very high current density (980 A/mm2 in the bare conductor). The measurement method is presented, as well as the results of the tests.The BOSSE project has been funded by the DGA (French Defence Procurement Agency)

Texto completoThe main objective of this dissertation is the detailed design, sizing, analysis and experimental validation of the sustainable wind generator. The proposed machine topology for the generator uses permanent magnets (PMs) from discarded hard disk drives (HDDs). The PM configuration inherently produces a non-uniform air gap flux-density distribution and the pole pitches of the PMs are relatively small. This would result to an unbalanced generator output and a number of stator inter-connecting leads, if conventional tooth-concentrated non-overlapping winding configurations are used. Hence, a concentrated full-pitch overlapping wave winding configuration is developed, which overcomes the aforementioned challenges. The proposed sustainable coreless axial flux generator is then analyzed with classical machine theory and verified by finite element analysis (FEA) software. It is shown that the traditional sizing approach for axial flux machines needs modification to accommodate the design of the proposed machine topology. For the numerical analysis, 3D-FEA is used to verify the 2Dmodel which is subsequently employed in the numerical analyses.

Texto completoEsta tese foi desenvolvida no contexto do aumento de cargas não lineares conectadas à rede que injetam harmónicas indesejadas e a consequente necessidade de controlo de qualidade da energia fornecida. A ausência de material de estudo relativo à simulação da tecnologia de armazenamento de energia em bobinas supercondutoras neste tipo de aplicação foi interessante para o estudo e desenvolvimento, com o benefício adicional de criar um projeto para catalisar novos desenvolvimentos. Esta correção de harmónicas foi obtida por meio de um filtro ativo composto por um conversor baseado numa fonte de tensão, um condensador e uma unidade de bobinas supercondutoras. O uso de tecnologia de armazenamento de energia em bobinas supercondutoras permite a utilização deste tipo de sistemas em fontes de energia renovável, mais especificamente em parques eólicos, atenuando as variações na produção e garantindo a qualidade de energia da rede elétrica. Deste trabalho resulta um resultado positivo do uso da tecnologia de armazenamento de energia em bobinas supercondutoras na correção de harmónicas e catalisa novas pesquisas de simulação e, possivelmente, uma aplicação prática que tenha como base os desenvolvimentos deste trabalho e das ferramentas fornecidas.

A superconducting magnetic energy storage (SMES) system can achieve high-speed, high-rating power exchange, including both active and reactive power. This thesis presents the dynamic simulations of a SMES system by means of the MATLAB/SIMULINK toolbox, power system blockset (PSB). However, with the modern powerful personal computer technology, the time consumed is nevertheless lengthy. In order to save the simulation time required, this thesis develops a simplified model of the SMES. The simplified model simulations can be completed in couple of seconds, and the final results agree with the one used by the PSB.

This thesis investigates a damping scheme using superconducting ing magnetic energy storage (SMES) unit to damp subsynchronous resonance (SSR) of the IEEE Second Benchmark Model, system-1 which is a widely employed standard model for computer simulation of SSR. In order to stabilize all SSR modes, simultaneous active and reactive power modulation and a proportional-integral-derivative (PID) damping controller designed by modal control theory are proposed for the SMES unit. Frequency-domain approach based on eigenvalue analysis and time-domain approach based on nonlinear model simulations are performed to validate the effectiveness of the proposed damping method.It can be concluded from the simulation results that the proposed damping scheme can effectively suppress SSR of the studied system.

This objective of this thesis is to investigate the operation of the superconducting magnetic energy storage (SMES) system. A SMES system can absorb and supply electric power instantly. It comprises a superconducting coil (SC) and a converter. The SC is for energy storage. Electric energy stored in a SC is in the form of dc current. Therefore, an interface that can exchange the stored energy in an SC is required. In this thesis, the converter can employ either a rectifier or a chopper. Several computer simulations demonstrate the dynamics of an SMES system.

This thesis develops a 5kW permanent-magnet synchronous generator drive for flywheel energy storage system (FESS). The generator drive system consists of a induction motor as the prime mover, a permanent- magnet synchronous generator, a three-phase three-wire inverter, the auxiliary power supplies, a micro-controller and the auxiliary driving circuits. The proposed space-vector based feed-forward current control uses the position information from the absolute encoder, DC-bus voltage and the inductance current to determine the instantaneous duty ratios of the power switches. The derivation of the proposed current control scheme is introduced. The driving performance is verified by the experimental results.

In recent years, flywheel batteries drew more attention in the energy storage system. A flywheel battery consists of flywheel, permanent-magnet synchronous motor and the driver. This thesis proposes a space-vector based feedforward current control for the permanent-magnet synchronous motor driver. The topology of this driver is a three phase full-bridge inverter. We use a micro-control unit, RX62T Group PLQP0112JA-A as the kernel of driver control, manufactured by Renesas Electronics. By sampling the signal of dc-link voltage, inductor current and the position of rotor, the microcontroller computes and generates three-phase PWM signals to the power switches. The driving performance has been verifiey by experimental results.

This thesis investigates the application of superconducting magnetic energy storage (SMES) units to damp subsynchronous resonance (SSR) occurred in a nonidentical two-machine system. The IEEE Second Benchmark Model, system-2 is employed to analyze the effectiveness of the proposed SMES unit with simultaneous active and reactive power modulation. A proportional-integral-derivative (PID) controller using speed deviations of the studied generators as feedback signals is designed by modal control theory to modulate the firing angle of the SMES unit. In order to have a complete and detailed research, a frequency-domain approach based on eigenvalue analysis and a time-domain approach based on nonlinear model simulation are both performed to validate the effectiveness of the proposed damping method. It can be concluded from the simulation results that the proposed damping scheme can effectively suppress subsynchronous torsional interactions of the studied system.

This dissertation presents a control scheme based on a superconducting magnetic energy storage (SMES) unit to achieve both power flow control and damping improvement of a large-scale offshore wind farm connected to a large power grid. The performance of the studied wind farm (WF) is simulated by an equivalent 80-MW induction generator (IG) consisting of forty 2-MW IGs while an equivalent 60-MW IG consisting of thirty 2-MW IGs is employed to study the characteristics of the marine-current farm (MCF). A damping controller for the SMES unit is designed by using modal control theory to contribute effective damping characteristics to the studied WF and the combined WF and MCF under different operating conditions. A frequency-domain approach based on a linearized system model using eigenvalue techniques to designed a damping controller. A time-domain scheme based on a nonlinear system model subject to disturbance conditions are both employed to validate the effectiveness of the proposed control scheme. It can be concluded from the simulated results that the proposed SMES unit combined with the designed damping controller is very effective to stabilize the studied WF and the combined WF and MCF under various operating conditions. The inherent fluctuations of the injected active power and reactive power of the WF and the combined WF and MCF to the power grid can also be effectively controlled by the proposed control scheme.

This dissertation is aimed at the development and operation controls of a DC micro-grid powered by wind permanent-magnet synchronous generator (PMSG) and DC source with hybrid energy storage devices. The DC sources are interfaced to the common DC bus via an interleaved DC/DC boost converter. As to the wind PMSG, after exploring the derated characteristics of PMSG systems with various AC/DC converters, a three-phase Vienna switch-mode rectifier (SMR) is developed as its interface to establish the common DC bus voltage of DC micro-grid. Its developed power is improved by proper commutation tuning and robust controls. The possible harvested DC or AC sources can be interfaced to the DC micro-grid via the embedded circuit components of Vienna SMR. Since the generating powers from various sources in a micro-grid are unpredictable and fluctuated, energy storage buffer is required to improve its power supplying quality. In the developed micro-grid, the battery/flywheel/super-capacitor hybrid energy storage system with bidirectional DC/DC interface converters is developed. And the droop control approach with adaptive predictive current control is proposed to yield good energy storage support control characteristics. Moreover, a chopped resistive dump load is equipped to regulate the energy balance when system energy surplus occurs. In test load arrangement, a single-phase three-wire (1P3W) inverter is established to yield 60Hz 220V/110V AC voltages for powering the home appliances. Good sinusoidal output voltage waveforms and dynamic responses due to load and DC-bus voltage changes are obtained by the proposed robust control schemes. When the renewable energy is surplus or insufficient, the microgrid-to-grid (M2G)/grid-to-microgrid (G2M) bidirectional operations can be also conducted by the established 1P3W inverter. Moreover, the bidirectional inter-connected operations between the developed micro-grid and the electric vehicle (M2V/V2M) can also be applicable. In addition, various motor drives, lighting devices and DC converter fed loads can be directly powered from the DC bus of the established micro-grid.

This thesis presents stability analysis of an integration of a superconducting synchronous generator (SCSG)-based offshore wind farm (OWF) and a permanent-magnet synchronous generator (PMSG)-based OWF connected to a power grid through a high-voltage direct current (HVDC) system using a supercapacitor energy-storage system and a high temperature superconducting wire. The q-d axis equivalent-circuit model is derived to establish the complete system model under three-phase balance conditions. Steady-state analysis characteristics of the studied system under different values of wind speed and transmission line are examined. Dynamic and transient simulations of the studied system subject to a wind-speed disturbance and a three-phase fault at the power grid are also carried out. It can be concluded from the simulation results that the proposed energy-storage systems can offer better effects on power-flow control and stability improvement of the studied system, while the system stability can also be further improved when the lead-lag damping controller is in service.
