Future Power System Security Program - reports and analysis

Below are links to the most recent AEMO reports related to this program. AEMO will continue to update this list throughout 2017.

August 2017 - Rule Change Proposal - Generator Technical Requirements (1.7 MB, pdf)

AEMO is requesting the Australian Energy Market Commission make changes to the National Electricity Rules that will reform the regulatory framework surrounding the connection of generation to the national grid.

The existing generator technical requirements were designed for an era of generating systems with different technological characteristics and performance capabilities. They have not been reviewed for 10 years.

The SA black system event demonstrated weaknesses in the existing generator performance standards that adversely impacted on the security and reliability of the power system, in particular the ability of connected generating systems to withstand, ride through and support the power system during major contingency events.

The proposed changes will build a modern, advanced and secure power system in an efficient manner, while minimising the potential for system weaknesses to arise.

August 2017 - Working Paper - Fast Frequency Response in the NEM (1.4 MB, pdf)

As the energy market transforms, the nature of frequency control in the National Electricity Market will change as new services are likely to be needed to complement existing mechanisms. This provides opportunities for applications of fast frequency response (FFR) to play a role in complementing existing frequency control. This working paper aims to develop a common language for discussion across industry, and provide early guidance on the suite of FFR services that may be valuable in future to assist in the efficient management of power system security. Stakeholder input is invited by 29 September 2017.

August 2017 - Addendum to Final Report:  Advice to Essential Services Commission of South Australia (ESCOSA) on technical standards for generator licensing (1.04 MB, pdf)

Following delivery of a report providing advice on proposed generator licensing standards to ESCOSA in March 2017 and ESCOSA's subsequent consultation process AEMO has issued an Addendum to its March Report. The Addendum presents revised technical advice to ESCOSA following input from Stakeholders. Further information, including ESCOSA's accompanying reporting is available here.

March 2017 - Technology Capabilities for Fast Frequency Response (GE Consulting Report)

AEMO engaged GE Consulting to explore the potential value of a Fast Frequency Response (FFR) service in the NEM, and to provide advice on how such a service should be specified. AEMO's interpretation of GE's findings, and intended next steps, are summarised in this covernote.

March 2017 - Submission to Independent Review into the Future Security of the National Electricity Market

AEMO’s submission to the Finkel Review provides specific answers to most of the questions posed in the consultation paper, but also outlines those matters AEMO considers to be of greatest urgency for the independent review to address.

February 2017 - Submission to AEMC System Security Market Frameworks Review Interim Report

AEMO has lodged a submission to the AEMC's System Security Market Frameworks Review in response to their Interim Report. In this submission, AEMO highlights the need to consider “hybrid” options for procuring inertia, which could drive long-term investment, allow for coordination between inertia procurement and managing system strength, and enable an efficient short-term mix of services. AEMO also identifies the need for new regulatory requirements to address the underlying drivers for system strength issues.

February 2017 - Submission to AEMC Rule change proposal - Protected events/ Emergency Frequency Control Schemes

AEMO has lodged a submission to the AEMC's Draft Determination for Rule change proposals on emergency frequency control schemes tabled by South Australia's Minister for Mineral Resources and Energy. In this submission, AEMO offers an alternative framework to what is proposed in the Draft Determination for administration of emergency frequency control schemes and a new proposed category of contingency events referred to as 'protected events 

January 2017 - FPSS Progress Report

This report provides a consolidated update of AEMO’s Future Power System Security (FPSS) work program, which aims to ensure power system security is maintained in the National Electricity Market (NEM) in the face of a changing generation mix and demand patterns.

January 2017 -  Visibility of Distributed Energy Resources

As part of the FPSS Program AEMO has developed the Visibility of Distributed Energy Resources (DER) report to outline the need for visibility of increasing penetrations of DER data to maintain power system security. The report details the potential impact DER has on market efficiency and reliability if their existence and behaviour is not visible or predictable to the operators. The report notes that that regulatory changes may be required to address information gaps to either make data available or consider opportunities to manage the power system in new ways.

December 2016 - Black System South Australia 28 September 2016, Third Preliminary Report

AEMO has published its third incident report into the South Australian (SA) state-wide power outage (referred to as the ‘SA region Black System event’) that occurred on Wednesday, 28 September 2016. This report, using collated information as at 7 December 2016, provides a consolidated view of all information published to date, together with further insight into AEMO’s pre-event planning and system restart process in South Australia, and power system and market operations during the Market suspension period. While this report focuses on the specifics of the SA region Black System event, it also highlights a number of challenges and measures relevant to broader considerations of how the changing power system responds to extreme events. While extreme events will occur from time to time, testing the wider resilience of the grid system, this report outlines for further analysis a number of preliminary recommendations to mitigate the risk of similar major supply disruptions in South Australia. This third report provides 15 preliminary recommendations with respect to industry’s preparation pre-event, actions during the event, the process for restoration, and communication during the market suspension.

November 2016 - Submission to VRET

AEMO’s submission to the Victorian Renewable Energy Target recommends that security and economic issues related to the Victorian grid are used as an evaluation criterion within the auction and that AEMO’s declared network functions be leveraged to assist this evaluation.

November 2016 - Submission to Qld 50% renewables target draft report

AEMO submitted a response to the draft report released by the Queensland Renewable Energy Expert Panel's consultation on achieving 50% renewables by 2030. AEMO's submission includes insights and advice from the work completed to date under the FPSS program. AEMO acknowledges and supports the Queensland Government’s intention to minimise the total cost of any renewable energy target on customers, and emphasises that the design of the final scheme should seek to support and/or complement important NEM investment and operational incentives as a means of building a stronger, more resilient interconnected power system. AEMO suggests further consideration be given to the market modelling. Better visibility of the possible outcomes of this projected level of intermittent generation on existing and future market participants would add to the understanding of the policy impacts and its consequences.

October 2016 - International Review of Frequency Control Adaptation

AEMO engaged DGA Consulting to undertake an international review of frequency control adaptation with the aim of understanding their experiences, and drawing out key insights for the NEM

October 2016 - Submission to AEMC Rule change proposal - Emergency Frequency Control Schemes.

AEMO has lodged a submission to the AEMC's Consultation Paper for Rule change proposals on emergency frequency control schemes tabled by South Australia's Minister for Mineral Resources and Energy.

In this submission, AEMO suggests clarification of areas of the NER to improve frameworks for emergency frequency control schemes and argues for the declaration of specific non-credible contingency events as 'protected events'- for which pre-emptive action can be taken to contain the consequence of the event(s) to an acceptable and well defined level.

September 2016 - Submission to the Energy Storage Registration Consultation Paper

AEMO made a submission to the Energy Storage Registration Consultation Paper released by the Energy Market Transformation Project Team (EMTPT), a working group of the COAG Energy Council. The paper sought to determine whether a battery storage registry was needed by industry, and how it should be operated. AEMO's submission encourages the EMTPT to consider a broader registry that would cater for a range of technologies.

August 2016 - FPSS Progress Report

This progress report outlines the FPSS program, and presents the outcomes of industry consultation on the long-term technical challenges to maintaining power system security in the context of changing generation mix. It also summarises key actions that are currently underway to understand the challenges and potential technical solutions.
