“…System-wide oscillations at 7 Hz and 19 Hz have been observed in the Australian grid supplying the southern and eastern region of the country. These were a result of increased penetration of IBRs in the West Murray region and reduction in the grid strength due to the displacement of synchronous generators (Modi et al, 2021). The current strategy to mitigate these oscillations and avoid any reliability event is to curtail IBRs in the West Murray regions (Badrzadeh et al, 2021).…”

“…Most stability events involving IBRs have been local in nature where a stability problem can be characterized as an unstable interaction between two systems-for example, interaction of a wind or PV power plant with the grid at its terminal because of low short-circuit strength of the grid or the presence of a series-compensated transmission line (ERCOT resonance event in the US, Adams et al, 2012; UK 2019 event NGET, 2019); an offshore wind power plant forming an unstable resonance with the offshore HVDC converter station (BorWin1, Germany, Buchhagen et al, 2015); and an HVDC converter or a STATCOM oscillating against the ac network at its terminal (China, Xie et al, 2017). Dynamic stability events involving wider network and numerous IBRs, however, are becoming more common because of ever increasing levels of IBRs and reduction in the grid stiffness due to the displacement of synchronous generators (Badrzadeh, et al, 2021;ERCOT, 2018;Shah et al, 2021b). See Sections 7.3.3 and 7.6 for studies towards 100% IBR systems.…”

“…[85], through the Generalised Eigenvalue Perturbation technique, for the feeder‐aggregation of the inverters. Australia, an IBR operational integration system leader, is facing several challenges such as the potentially adverse interactions between IBRs provoking low‐frequency oscillations [86]. Australia is now requiring to revise extensively the control tuning to mitigate these phenomena.…”

Electrical power systems are continuously upgrading into networks with a higher degree of automation capable of identifying and reacting to different events that may trigger undesirable situations. In power systems with decreasing inertia and damping levels, poorly damped oscillations with sustained or growing amplitudes following a disturbance may eventually lead to instability and provoke a major event such as a blackout. Additionally, with the increasing and considerable share of renewable power generation, unprecedented operational challenges shall be considered when proposing protection schemes against unstable electro-mechanical (e.g. ringdown) oscillations. In an emergency situation, islanding operations enable splitting a power network into separate smaller networks to prevent a total blackout. Due to such changes, identifying the underlying types of oscillatory coherency and the islanding protocols are necessary for a continuously updating process to be incorporated into the existing power system monitoring and control tasks. This paper examines the existing evaluation methods and the islanding protocols as well as proposes an updated operational guideline based on the latest dataanalytic technologies.

“…New alternatives are required to better understand the current challenges faced by modern grids and reduce their computational time [9]. Real-time simulation (RTS) in electromagnetic transient (EMT) domain provides more capabilities to address the challenges of these modern and complex power systems [10], [11], [12] enabling: i) flexibility for accurate representation of power and energy systems, ii) detailed power system studies, iii) comprehensive analysis of power electronics based systems, iv) control and power hardware-in-loop (HiL) testing, and v) detailed performance validation.…”

Development of Power System Models for Distributed Real-Time Simulations

et al. 2022

This paper proposes a general methodology for the development of power system models suitable for distributed real-time simulations (D-RTS) based on topology, simulator interfaces and data exchange. D-RTS have risen as functional alternatives that can combine remote and multi-vendor resources for large-scale power system simulations via a virtual connection. However, previous work focused on combination of separate models and not the performance of D-RTS when splitting a single monolithic model, failing to study the behaviors of D-RTS, including, synchronization and accuracy. The proposed methodology is used to develop distributed models of two widely used testbed large power systems, the IEEE Australian Benchmark model and the IEEE 300-Bus system. These testbeds are selected as they can be simulated as both monolithic and distributed models in available simulators in order to validate both the methodology and resulting model performance. The obtained results and comparison between monolithic and distributed models support the proposed approach and demonstrate the performance of D-RTS under both steady-state and transient operations in multiple scenarios.INDEX TERMS Co-simulation, distributed real-time simulation (D-RTS), geographically distributed realtime simulation (GD-RTS), real-time simulation (RTS)
