Future SWIS requirements

AEMO chairs the Power System Operation Working Group (PSO-WG), a gathering of government, market participant and other industry representatives that advises on the development of changes to the Market Rules that relate to matters of power systems operation.

The working group recommendations inform the Western Australian Government Energy Transformation Strategy as part of the Delivering the Future Power System work stream.

Contingency response technical framework

The Energy Transformation will include a new Essential System Service Framework to ensure that support services can be securely and efficiently procured for the future power system. These conditions will be characterised by higher proportions of intermittent and non-synchronous generation, which creates greater and more sophisticated demands on the resilience of the system to withstand sudden major shocks (“contingency events”).

AEMO has developed and validated a technical framework to both quantify and manage these future challenges. The approach is described in the technical proposal below, which has been presented to and reviewed by the PSO-WG:

The framework will be used as the technical underpinning in the market design for future Essential System frequency control services.

To participate in the developments of similar such design of the future Wholesale Electricity Market, register to join the Power System Operation Working Group.

Information regarding the timeline for development and implementation of market services can be found in the Energy Transformation newsletter.

Publication of Generator Performance Guideline

Western Power and the Australian Energy Market Operator (AEMO) held a joint Industry Forum in April 2019 to consult on the proposed draft Generator Performance Guidelines. The Guideline detailed proposed future revisions to the generator performance standards for new generator connections.

Participants were invited to provide further feedback post the forum for Western Power and AEMO to consider in finalising the Guidelines and several responses were received.

The responses from Generators and manufacturers confirmed that they can comply with the guideline requirements and there would be no challenges for the varying technology types.

Clarity was sought on potential modification requirements for existing generators and it is confirmed that this work will be undertaken by Western Power with support of AEMO as part of the consultation process to the implement the guidelines as rules.

AEMO will continue to work with Western Power and the Energy Transformation Implementation Unit (ETIU) to further update and refine the Guideline prior to implementation through the appropriate regulatory instrument.

The Generator Performance requirements are described in the guideline below:
