Parallel operation of a synchronous generator and a virtual synchronous generator under unbalanced loading condition in microgrids

2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia), 2016

Parallel operation of a synchronous generator (SG) and an inverter-interfaced distributed generator (DG) is required in some islanded microgrids. However, dynamic performance of a small SG is usually poor, i.e. the rotor speed usually deviates largely during a loading transition, due to small inertia and slow governor response. Moreover, unbalanced SG current should be prevented to protect the SG, which ...

  • Parallel operation of a synchronous generator and a virtual synchronous generator under unbalanced loading condition in microgrids

    Parallel operation of a synchronous generator (SG) and an inverter-interfaced distributed generator (DG) is required in some islanded microgrids. However, dynamic performance of a small SG is usually poor, i.e. the rotor speed usually deviates largely during a loading transition, due to small inertia and slow governor response. Moreover, unbalanced SG current should be prevented to protect the SG, which makes this issue more challenging. In this paper, a control method for the inverter-interfaced DG based on virtual synchronous generator (VSG) concept is proposed, to improve the overall performance of parallel operation of SG and DG. Double decoupled synchronous reference frame (DDSRF) decomposition, SG negative-sequence current compensation, modified calculation methods for power and voltage, and transient virtual stator impedance are integrated into the proposed VSG control scheme, and tuning methods of main control parameters are discussed. It is demonstrated by simulation results that the proposed DG control method alleviates the SG rotor speed deviation and DG overcurrent during a loading transition, and eliminates the negative-sequence components of the SG output current.

  • Test Method for Inertia and Damping of Photovoltaic Virtual Synchronous Generator Based on Power Angle Transfer Function

    Virtual synchronous generator technology is a new generation of renewable energy generation control technology in recent years. By making up the droop characteristics and rotation inertia of the synchronous generator in the traditional power system, the renewable energy generation has the characteristics of the traditional generator. At present, there is no unified testing method for PV virtual synchronous generators with different technical routes, and the technical regulations and test regulations of the related virtual synchronous generators at home and abroad are in blank. In this paper, a test method for rotating inertia and damping of PV virtual synchronous generator based on the function of power frequency transfer function is proposed and verified by a hardware in the loop simulation platform. This method does not need to take into account the two order and above characteristics of the virtual synchronous generator. It is suitable for various types of PV virtual synchronous generator rotation inertia test, and solves the problem of the lack of standardized test method for the damping characteristic of the virtual synchronous generator.

  • Static Synchronous Generator Model: A New Perspective to Investigate Dynamic Characteristics and Stability Issues of Grid-Tied PWM Inverter

    With increasing penetration of the renewable energy, the grid-tied PWM inverters need to take corresponding responsibilities for the security and stability of future grid, behaving like conventional rotational synchronous generator (RSG). Therefore, recognizing the inherent relationship and intrinsic differences between inverters and RSGs is essential for such target. By modeling the typical electromechanical transient of grid-tied PWM inverters, this paper first proves that PWM inverters and RSGs are similar in physical mechanism and equivalent in mathematical model, and the concept of static synchronous generator (SSG) is thereby developed. Furthermore, the comprehensive comparison between RSG and SSG is carried out in detail, and their inherent relation is built. Based on these findings, the rationality and feasibility of migrating the concepts, tools, and methods of RSG stability analysis to investigate the dynamic behaviors and stability issues of SSG is therefore confirmed. Taking stability issues as an example, the criteria of small signal and transient stability of a typical grid-tied PWM inverter is put forward to demonstrate the significance of the developed SSG model (including synchronizing coefficient, damping coefficient, inertia constant, and power-angle curve), providing clear physical interpretation on the dynamic characteristics and stability issues. The developed SSG model promotes grid- friendly integration of renewable energy to future grid and stimulates interdisciplinary research between power electronics and power system.

  • An improved synchronverter model and its dynamic behaviour comparison with synchronous generator

    As widely-used energy transform device, inverter plays important role in microgrids and distribution generation (DG). Generally, according to its control object, inverter's controllers can be classified into at least three kinds: constant PQ, droop control and synchronverter (SV) or virtual synchronous generator (VSG). In this paper, an improved synchronverter model is presented. By means of powerful computation ability of digital signal processor (DSP), all basic parts of SG, are reconstructed though program code running in DSP and thus become virtual parts of SV. In this way, SV has absolutely similar structure with actual SG. This similarity ensures they always have really same dynamic behaviour. When stability of multi-SVs- dominated microgrids investigated, inverter model can be replaced by SG model without any accuracy losses. At the same time, this replacement provides a possibility to transfer high matured stability theories which are already applied for large power grid into stability analysis of microgrids or DG. Detailed design methods for SV controller are presented. Via Simulink, dynamic responses of SV and SG are compared under different operation situations. Results prove that SV has same response with similar parameter SG not only in steady state but also in whole process.

  • Hardware in Loop Simulation Test of Photovoltaic Virtual Synchronous Generator

    Photovoltaic power generation is mainly connected to the grid by grid- connected inverter. Compared with the traditional synchronous generator, it has the advantages of flexible control and quick response, but there is also lack of inertia and damping. With the increasing of the permeability of the photovoltaic power supply, the rotating spare capacity and the moment of inertia in the power system are relatively reduced, which poses a severe challenge to the safe and stable operation of the power grid. The introduction of photovoltaic virtual synchronous generator makes the grid connected inverter have similar operation characteristics of synchronous generator and improve the stability of power system. In this paper, a hardware in loop simulation test scheme based on RT-LAB is proposed for PV virtual synchronous generator, and a simulation test platform is set up to study the testing method of the performance of the PV virtual synchronous generator. Based on this platform, the characteristics of the PV virtual synchronous generator, such as the inertia and the primary frequency modulation, are carried out. The test results show that the simulation platform is correct.

  • Synchronous generator based wind energy conversion system (WECS) using multi-modular converters with autonomous controllers

    Among various options available for wind energy conversion systems, this paper focuses on direct driven Synchronous Generator (SG) based variable speed wind turbine (VSWT). Generally SG is connected to the power grid via full-size power converters. But with the growing trend of multi mega watt turbine installation, the idea of modular- converter units is gaining popularity. Multi-module topology has proven its supremacy in terms of reliability, efficiency and harmonic reduction over its medium voltage full rating converter counterpart. Research conducted earlier on modular converter system either had a centralized control structure or was in master/slave configuration. This paper explores the option of autonomous controller for modular converter system. One of the main challenges faced in design of autonomous controller is to ensure equal power sharing among the operating units without employing any communication between them. Also in order to enhance system harmonic performance, control structure should enable interleaving of operational units under all conditions. Such an autonomous controller will greatly improve system reliability/redundancy. To test the developed autonomous controller, simulation is carried out using MATLAB.

  • Direct drive synchronous generator wind turbine models for power system studies

    The large-scale integration of wind power into modern power systems has set novel challenges for wind turbine modeling and analysis. Accurate modeling of different wind turbine technologies is becoming a necessity as wind turbines replace conventional units in the production side. This paper describes models for two major variable speed wind turbine types namely Electrically Excited Synchronous Generator (EESG) and Permanent Magnet Synchronous Generator (PMSG). Steady state principles of both types are analyzed and mathematical modeling of crucial components is described. The behavior and operation of the system during stochastic wind speed series is simulated using software tools Matlab and PowerFactory. The two configurations are accessed based both on the steady state characteristics and the control system designs. The paper covers a wide range of control methods, which are implemented in both wind turbine schemes. Regarding the PMSG scheme, an advanced damping controller to damp possible oscillations excited in the drive train is presented and its contribution to the safe operation of the wind turbine is explained. In the alternative direct drive scheme (EESG) three different control methods applied in the electrical system are presented.

  • A virtual synchronous generator control strategy for distributed generation

    As an approach to making distributed energy resources with virtual inertia, the virtual synchronous generator control strategy plays a significant role in the micro-grid stability. On the basis of theoretical derivation and analysis of virtual synchronous generator control and micro-grid, an overall virtual synchronous generator control strategy of distributed energy resources inverter was proposed to improve the stability of micro-grid. The outside control of distributed inverter was constructed by using synchronous generator's rotor motion equation, primary frequency regulation feature and the delay characteristic of reactive power regulation. And the bottom control was adopted by the vector relationship of synchronous generator grid-connected to grid. Finally, a simple micro-grid digital simulation system based on Matlab/ Simulink was built, and the results show that the proposed control method has an important effect to support the frequency stability of micro- grid.

  • IEEE Draft Guide for Synchronous Generator Modeling Practices and Parameter Verification with Applications in Power System Stability Analyses

    Categorizes three direct-axis and four quadrature-axis models, along with the basic transient reactance model. Discusses some of the assumptions made in using various models and presents the fundamental equations and concepts involved in generator/system interfacing. Covers, generally, the various attributes of power system stability, recognizing two basic approaches. The first is categorized under large disturbance nonlinear analysis; the second approach considers small disturbances, where the corresponding dynamic equations are linearized. Applications of a range of generator models are discussed and treated. The manner in which generator saturation is treated in stability studies, both in the initialization process as well as during large or small disturbance stability analysis procedures is addressed. Saturation functions that are derived, whether from test data or by the methods, of finite elements are developed. Different saturation algorithms for calculating values of excitation and internal power angle depending upon generator terminal conditions are compared. The question of parameter determination or verification is covered. Two approaches in accounting for generator field and excitation system base quantities are identified. Conversion factors are given for transferring field parameters from one base to another for correct generator/excitation system interface modeling, Suggestions for modeling of negative field currents and other field circuit discontinuities are included.

  • VSC Control and Parameters Design Based on Virtual Synchronous Generator

    To cope with the problems that the VSC lacks inertia and synchronous generator controls slowly, the paper combines the advantages of VSC and synchronous generator together to present a control scheme of virtual synchronous generator and a parameters design method. To solve the mutual influence of droop and virtual damping coefficients, a method of combining output frequency and line frequency feedback control is proposed to decouple the two coefficients regulation process while without using the differentiation. Mode switching between constant power and droop control under frequency large disturbance in large scale based on frequency hysteresis control is proposed to maintain system stability. The switching process is realized only through the outer power loop while the inner loop stays the same. At last, a quasi- synchronous-generator parameters design method is established combining the flexible and rapid control characteristics of VSC and the synchronous generator unit's self-droop and self-synchronizing characteristics. The simulation result verified the correctness of theoretical analysis and control scheme.
