“…The usage of these systems includes for example non-synchronous interconnection, control of power flow, and modulation to increase stability limits. Adding a supplementary damping controller to the HVDC converters can improve the modal damping of the turbine-generator system and thus allows higher levels of compensation ratio of the power system [21] [ 22].…”

This paper presents the effect of the high voltage direct current (HVDC) transmission system based on voltage source converter (VSC) on the sub synchronous resonance (SSR) and low frequency oscillations (LFO) in power system. Also, a novel adaptive neural controller based on neural identifier is proposed for the HVDC which is capable of damping out LFO and sub synchronous oscillations (SSO). For comparison purposes, results of system based damping neural controller are compared with a lead-lag controller based on quantum particle swarm optimization (QPSO). It is shown that implementing adaptive damping controller not only improves the stability of power system but also can overcome drawbacks of conventional compensators with fixed parameters. In order to determine the most effective input of HVDC system to apply supplementary controller signal, analysis based on singular value decomposition is performed. To evaluate the performance of the proposed controller, transient simulations of detailed nonlinear system are considered.

“…With such a response speed, the VSC is able to control transients and flicker, and keep the AC bus voltage constant, enhancing the transient stability of the system. Furthermore, through fast active and reactive power modulation, VSCs also provide effective damping for mitigating electromechanical oscillations [1,27,67,69,70,71]. [71] presents research results regarding the improvement of sub-synchronous torsional damping by VSC HVDC systems.…”

It is concluded that the choice of active power control mode, instead of DC voltage control, is more beneficial for the damping control.…”

Voltage Source Converter (VSC) High Voltage Direct Current (HVDC) connection has become a new trend for long distance offshore wind power transmission. It has been confirmed by a lot of research that the maximum distance of a High Voltage Alternative Current (HVAC) sub-marine cable transmission system is limited due to surplus charging current of the cables. The VSC HVDC transmission system has the ability to overcome the limitation and offers other advantages over the HVAC transmission system. This paper is to review the VSC HVDC transmission technology and its application for offshore wind power integration. Firstly, the main components, configuration and topology of the VSC HVDC transmission system are described.Secondly, the converter control system and control strategies are presented. Following that, the capabilities of the VSC HVDC technology are described. Finally, the focus is given on the control methods of the VSC HVDC transmission system for fulfilling grid code requirements concerning Low Voltage Ride-Through (LVRT) and frequency regulation.

“…With the expected high penetration levels of modern VSCbased applications in power systems, such as wind farms [16], photovoltaic power plants, high-voltage dc (HVDC) transmission systems [7], distributed generation [19], and microgrids [20], the functionality of existing VSCs can be increased by participating in system damping control [21]. Recently, the utilization of a VSC-based HVDC-link to mitigate SSR in a seriescompensated Great Britain network is proposed [22].…”

This paper presents a new technique to damp subsynchronous torsional oscillations in a seriescompensated system with multimass synchronous generator by reshaping the output impedance of an electrically nearby voltage-source converter (VSC; e.g., interfacing a high-voltage dc transmission system or wind farm). The incremental output admittance of a VSC that is constructed by the circuit components and control parameters of a VSC is the key element for VSC-grid interactions. The proposed subsynchronous resonance damping controller is based on reshaping the virtual output admittance of the interfacing VSC-based system to ensure positive damping in the vicinity of torsional modes. The proposed reshaping technique uses the voltage at the point of common coupling in cascaded compensators to magnify the positive resistance without using generator or turbine speed and/or torque perturbations. Time-domain simulation results and laboratory-scale experimental results are presented to validate the theoretical analysis and show the effectiveness of the proposed approach.
