“…From ( 16), the value of Δ𝜓 is dependent on the value of part B, and to minimise the under-reach and over-reach issues, the value of B should be as close to zero as possible. Additionally, the following conclusions can be derived based on (16).…”

This paper presents a comprehensive evaluation of the HVDC system's impact on distance protection via systematic and realistic experimental tests, along with theoretical analysis of the root causes of the identified compromised protection performance. A methodology for quantifying the impact of Synchronous Compensation (SC) in supporting the distance protection operation is also established. In this work, the performance of two widely used physical distance protection relays have been evaluated using a realistic Hardware'In'the'Loop (HIL) testing environment, where a total of 480 cases have been tested under a wide range of system scenarios. Representative cases with compromised protection performance are selected, where issues of under/over'reach, faulted phase selection and impedance measurement are identified and analysed. Furthermore, a method for quantifying the required SC level to address the under/over'reach issues resulting from HVDC systems is presented. The method establishes the relationship between the angle difference of the two'end fault current infeeds of the protected line and the SC level. Based on this relationship, the required SC capacity to constrain the angle difference within a targeted limit can be estimated, which offers a useful tool for system operators to appropriately size the SC's capacity with additional valuable insights from the distance protection perspective.

<p> Deployment of Synchronous Condensers (SynCons) has become one popular solution in accommodating large-scale renewable energy resource (RER) for existing power systems. In this paper, rotor angle instability of SynCon is investigated. To derive intuitive understandings and quantitative analysis, the swing equations of the equivalent synchronous generators (ESG) are derived. The Lyapunov’s direct method is employed to analyze the attraction domain for a typical benchmark system. Based on that, a rotor angle stability margin index is developed and an adaptive low voltage ride through (LVRT) control strategy is proposed for assessment and enhancement of rotor angle stability. The criterion and effectiveness are verified with on EMT simulations, respectively. </p>

The objective of the studies presented in this paper aims to demonstrate that the deployment and operational control of synchronous condensers in the GB transmission system can mitigate a part of the challenges associated with the high penetration of renewable energy sources. These include the decline of short circuit level and the subsequent impact on transmission line protection schemes. The case studies include scenarios such as transmission-level faults, fault level calculation and assessment of distance protection performance. The results and observations included in the paper aim to highlight the means and supporting evidence for the benefits of synchronous condensers in the view of a fully de-carbonised power system.
