“…It is a service that improves damping of electromechanical oscillations (typically 0.2 − 2 Hz) in an ac grid by injecting a damping power. VSC-HVDC converter can achieve POD by modulating either active or reactive powers [1], [2]. It was found in [2] that active power modulation gives more robust performance regarding ac voltage variations.…”

“…VSC-HVDC converter can achieve POD by modulating either active or reactive powers [1], [2]. It was found in [2] that active power modulation gives more robust performance regarding ac voltage variations. However, a side effect of using active power is that the oscillation is exported to the dc side since active power is balanced instantaneously.…”

Abstract-This paper presents a control scheme that utilizes energy storage of the Modular Multilevel Converter (MMC) for Power Oscillation Damping (POD) service. Such a service is used to enhance grid stability by providing damping power in the electromechanical (0.2-2Hz) dynamics range. The scheme uses compensated modulation with average energy control. The aforementioned service comes at the cost of additional energy storage requirement for the MMC. A worst case estimate of this additional capacity, together with potential options to obtain it, is also addressed in this paper. The scheme is validated by simulation studies on a four terminal HVDC test grid.

Abstract-This paper proposes a new approach of providing ancillary services to AC and DC grids from offshore wind power plants (OWPPs), connected through multi-terminal HVDC network. A coordinated control scheme where OWPP's AC grid frequency modulated according to DC grid voltage variations is used to detect and provide the ancillary service requirements of both AC and DC grids, is proposed in this paper. In particular, control strategies for onshore frequency control, fault ridethrough support in the onshore grid, and DC grid voltage control are considered. The proposed control scheme involves only local measurements and therefore avoids the need of communication infrastructure otherwise required for communication based control, and thus increases the reliability of the control system. The effectiveness of the proposed control scheme is demonstrated on a MTDC connected wind power system developed in DIgSILIENT PowerFactory.Index Terms-ancillary services, fault ride through, frequency control, HVDC grid voltage control, integration of wind power.
