Overview

Through working with Network Service Providers (NSPs) and market participants, AEMO has found that there is uncertainty on the requirements of clause S5.2.5.10 “Protection to trip for unstable operation” of the National Electricity Rules (NER) and relating the requirements to the Power System Stability Guidelines (PSSG). As such, AEMO has identified an opportunity to establish a consistent understanding and approach for the technical requirements under, and compliance with, S5.2.5.10 for asynchronous generating systems and reactive plant such as Static Var Compensators (SVCs) and Static Synchronous Compensators (STATCOMs). 


AEMO has prepared an
initial summary guide to give a broad range of stakeholders a summary perspective on some of the challenges to date, an overview of a proposed S5.2.5.10 guideline, and an opportunity to provide input to the development of the said guideline.

Submissions

AEMO invites written submissions in response to the initial summary guide. There are three key questions, your input to these areas will assist in progressing the draft guideline. Submissions should be sent by email to contact.connections@aemo.com.au, to reach AEMO by 5.00pm (AEDT) on 24 August 2022.


All submissions will be published on AEMO’s website, other than confidential content.
Please identify any parts of your submission that you wish to remain confidential and explain why. AEMO may still publish that information if it does not consider it to be confidential but will consult with you before doing so.

Please note that material identified as confidential may be given less weight in the decision-making process than material that is published.

Submissions received after the closing date and time will not be valid. Any late submissions should explain the reason for lateness and the detriment to you if AEMO does not consider your submission.
