Open Energy Networks Project

Key activities of this project include: 

• Initial consultation to explore the proposed frameworks required to integrate DER, including a more active Distribution System Operator (DSO) and the advent of distribution markets. Three frameworks were considered including the Single Integrated Platform, the Two-Step Tiered and the Independent DSO.
• International Review to identify system operators that have begun considering system architecture frameworks and defining the roles, responsibilities and control coordination for real-time operation of DER. Global discussions have involved a range of conceptual models for the roles of Distribution System Operator (DSO), Distribution Operator (DO) and Transmission System Operator (TSO). Specifically, Total TSO, Hybrid DSO, and Total DSO.
• Smart Grid Architecture Model (SGAM) developed by EA Tech is the outcome of three possible models for DSO architecture. All interactions and interfaces were developed for each model to represent the complex system into its individual parts.
• Cost Benefit Analysis to determine the total net benefit of optimising DER for Australia by 2030. The key benefits are assumed to arise from minimising costs associated with electricity generation, transmission and distribution, given increasing levels of DER penetration in the electricity grid. 

Initial Consultation Interim Report – June 2019

International Review

An International Review was commissioned by AEMO to support the Open Energy Networks Project. This review focused on progress made internationally and the steps taken to develop DER coordination frameworks between Distribution and Transmission networks.

Smart Grid Architecture Models – EA Tech Report

In collaboration with EA Tech, a series of functional specification workshops were conducted to develop the detailed Smart Grid Architecture Models (SGAMs) for each of the proposed energy market models, including the resultant 'Hybrid model'.

Further information about each model can be found in the Energy Networks report:

The Functional Specification Workshops – held in Sydney, Melbourne and Perth – adopted a similar approach to that undertaken in the UK, as discussed in the above-mentioned report.

Cost Benefit Analysis Framework

CSIRO was commissioned to review work already performed in Australia and internationally on cost-benefit analysis of distribution coordination and optimisation of DER.
Based on the review’s findings, the report proposed a framework for a full cost-benefit analysis to determine the total net benefit of optimising DER for Australia by 2030.
