“…Linear power flow analysis lends itself to the formulation of linear sensitivity methods, which facilitate computationally efficient contingency analysis. In [12], sensitivity factors are based on the first-order Taylor series approximation, yet the power flow calculation itself remains iterative. A linear and non-iterative application of sensitivity factors for contingency analysis was demonstrated in [22].…”

The increasing integration of renewable energy sources calls for an extension of transmission capacity for transporting power towards load centers. Given the involved distances, the integration of high voltage DC connections into AC transmission grids becomes a reality. The interest in such AC-DC transmission grids has been further driven by the potential of multi-terminal HVDC grids interfaced via voltage sourced converters. Their capability of power flow control can contribute to overload mitigation, especially also in case of contingencies. In security analysis of AC grids, the application of linear sensitivity methods for very fast analysis of various contingencies has become established. In this article such contingency analysis is developed for integrated AC-DC transmission grids. Power transfer distribution and line outage distribution factors are reformulated to yield the novel AC-DC power transfer compensation and line outage compensation factors. Those account for the fact that voltage sourced converters allow for controlling power flows. A further innovation is the optimization for the fast identification of AC-DC voltage sourced converter operating point adjustments to mitigate system-wide overloads. Accuracy, principal functionality, robustness, and computational efficiency of the proposed methodology are demonstrated. Scenarios were studied on a modified IEEE 39-bus system and a hypothetical future German power grid.

“…The various control schemes of VSC-HVDC and LCC-HVDC structures on smallsign durability are explored in [15,16]. In line with that, the performance of control techniques of VSC-HVDC is enhanced with multi-objective optimization [17,18]. The control techniques on the inverter station of the LCC-HVDC system along with the effects of a phase-locked loop (PLL) on small-signal stability are studied in [19].…”

High-voltage direct current (HVDC) has received considerable attention due to several advantageous features such as minimum transmission losses, enhanced stability, and control operation. An appropriate model of HVDC is necessary to assess the operating conditions as well as to analyze the transient and steady-state stabilities integrated with the AC networks. Nevertheless, the construction of an HVDC model is challenging due to the high computational cost, which needs huge ranges of modeling experience. Therefore, advanced dynamic modeling of HVDC is necessary to improve stability with minimum power loss. This paper presents a comprehensive review of the various dynamic modeling of the HVDC transmission system. In line with this matter, an in-depth investigation of various HVDC mathematical models is carried out including average-value modeling (AVM), voltage source converter (VSC), and line-commutated converter (LCC). Moreover, numerous stability assessment models of HVDC are outlined with regard to stability improvement models, current-source system stability, HVDC link stability, and steady-state rotor angle stability. In addition, the various control schemes of LCC-HVDC systems and modular multilevel converter- multi-terminal direct current (MMC-MTDC) are highlighted. This paper also identifies the key issues, the problems of the existing HVDC models as well as providing some selective suggestions for future improvement. All the highlighted insights in this review will hopefully lead to increased efforts toward the enhancement of the modeling for the HVDC system.
