Martinez-Sanz I, Chaudhuri B, Strbac G, 2012, Impact of wind penetration and HVDC upgrades on stability of the GB transmission system

Several case studies are presented in this paper to better understand the impact of planned network changes on the dynamic stability of the future Great Britain transmission system. These studies have been conducted on a small network that is reasonably representative of the small signal stability problems present in the UK power system. The effect of wind penetration and HVDC links on the existing low frequency inter-area oscillations is analysed and interpreted for different possible future scenarios by observing the change of damping and frequency of this mode in response to these changes. © 2012 IEEE.

Pipelzadeh Y, Chaudhuri B, Green TC, 2012, Inertial Response from Remote Offshore WindFarms Connected Through VSC-HVDC Links: ACommunication-less Scheme, IEEE Power and Energy Society General Meeting 2012

A communication-less scheme that allows remoteoffshore wind farms connected through HVDC links to participatein primary frequency control and contribute to systeminertia is discussed in this paper. As a HVDC link decouples theoffshore system from the onshore side, real-time communicationof onshore frequency is normally required for the primaryfrequency control loop of the wind farms. Dependance on remotecommunication which could be unreliable at times is a problem.To obviate the need for communication, appropriate droopcontrol on the offshore and onshore converters is used in thispaper to translate the variation in onshore frequency to anequivalent variation on the offshore end. Thus the need for communicatingonshore frequency to the offshore side is mitigatedwhich ensures reliable operation. Such a communication-lessscheme is compared against the conventional approach involvingremote communication of onshore grid frequency to the windfarm site. Along side physical and analytical justification, a casestudy is presented to demonstrate that the communication-lessscheme performs similar to the conventional one in terms ofreducing grid frequency variations.

Piplezadeh Y, Chaudhuri B, Green TC, 2012, Control Coordination Within a VSC-HVDC Link for Power Oscillation Damping: A Robust Decentralized Approach Using Homotopy, IEEE Transactions on Control Systems Technology

Power oscillations can be damped effectivelythrough modulation of both active and reactive power of a voltage source converter based high voltage direct current link. The challenge, however, is how to coordinate the control action properly at the two ends of the link without using a centralised control scheme, which requires fast communication of control signals to remote actuator (converters) sites. A full centralised controller may result in a closed-loop performance worse than that of an open loop in case of a communication loss of feedback signal(s). Alternatively, with a block-diagonal control structure, the individual control loops are decoupled from each other, which is not only easier to implement in a decentralized way, but also shown to guarantee a certain level of performance. Here, the concept of homotopy is applied to obtain a single block-diagonal controller from a set of full controllers, individually designed to ensure specified closed-loop performance for a set of operating conditions. Simulation studies in DIgSILENT PowerFactory are carried out on two test systems to demonstrate both the robustness and control coordination in a decentralised framework.

Pipelzadeh Y, Chaudhuri B, Green TC, 2011, Coordinated Damping Control Through MultipleHVDC Systems: A Decentralized Approach, IEEE Power and Energy Society General Meeting 2011

The role of multiple HVDC links - both CSC and VSC - in improving the AC system dynamic performance is presented here. An Australian equivalent system with three critical interareamodes is considered to illustrate the case study on DIgSILENT PowerFactory. Subspace-based multi-input-multi-output(MIMO) system identification is used to estimate and validatelinearized state-space models through pseudo random binary sequence (PRBS) probing in DIgSILENT PowerFactory. Choice of appropriate input-output combinations is done through modalresidue analysis taking note of not only the magnitudes but also the phase angles. The decentralized control design is posed as an optimization problem and solved using an evolutionary technique. The results are validated through linear analysis andnon linear simulation in DIgSILENT for two extreme (light and heavy loading) operating conditions.

Pipelzadeh Y, Chaudhuri B, Green TC, 2011, The Impact of Significant Wind Penetration and HVDC Upgrades on the Stability of Future Grids: A Case Study on the Australian Power System, CIGRE International Symposium 2011

Wind power has been the fastest growing energy generation sector worldwide in recent years. Large on- and off-shore wind farms have a considerable impact on system security and stable system operation. Therefore its influence on the dynamic stability of the system must be addressed. For turbines above 1MW, doubly-fed induction generators (DFIG) are the most widely used concept. However in many countries such as U.K and Germany, full-rated converter (FRC) have also gained vast amount of market penetration.To address this, the paper presents studies performed in DIgSILENT PowerFactory aimed at ascertaining the impact that DFIG and FRC have on the oscillation modes of the power system. The feasibility, advantage and disadvantages of various options are discussed.Wind generators can be connected to existing power transmission networks spanning over long distances and ultimately causing interaction between wind-farms and transmission systems. The benefit of utilising HVDC (classical and/or Voltage- source) within an ac network for transporting large amounts of wind power to remote load locations is studied.Wind farms consist of large number of generators of relatively small size. Both types of variable speed wind generators (DFIG and FRC) have been modelled in detail in PowerFactory DIgSILENT. Model aggregation techniques are applied to reduce computation time. Different control strategies for VSC-HVDC and “classical” Thyristor-based HVDC links are presented and analyzed via network simulation. A case study is presented based on the equivalent SE Australian power system, an IEEE benchmark system for dynamic studies, with appropriate reinforcements introduced to accommodate wind generation and HVDC transmission systems.This paper is focused on the small-signal stability issues and analyses the impact of various aspects like generator technology, hybrid AC/HVDC transmission for getting a thorough understanding about the impact of these on the overall system sta

Berggren B, Majumder R, Ray S, Chaudhuri B, Chaudhuri NRet al., 2011, Power or Voltage Oscillation Damping in Power Systems

The invention provides a method, device and computer program product for providing improved control of power or voltage oscillation damping in a power transmission system. The device comprises a magnitude obtaining element (30) configured to obtain an instantaneous magnitude of a signal ( I ΔP I ) representing a deviating oscillation in at least one element (12) of the power transmission system, a slope investigating element (58) configured to determine the rate of change of the signal, and a first processing block (34) comprising an integrating element (38) configured to integrate the instantaneous magnitudes with an integrating factor (Ki) that is based on the determined rate of change. The first processing block is further configured to form a phase compensation angle (ϕc) based on the integrated instantaneous magnitude for use in a damping control signal generating unit in order to provide power or voltage oscillation damping of the system.
