Completed Projects

The following provides a short description of some of the projects completed by ROAM to illustrate the range of ROAM's capabilities in energy modelling services.

 

Western Power – East Kimberley Energy Supply/Demand Optimisation Study – March to May 2005

This assignment required consultation with many stakeholders in the development of the region to establish possible candidates for new power development including a field trip to Perth and the East Kimberley area. A complete integrated resource plan of generation, transmission and demand was developed and assessed for a 25-year outlook for various regional demand development options.

 

This project required significant development of the 2-4-C software to include an in depth hydrological model of the Lake Argyle reservoir on which the region is entirely dependent on for both power generation and irrigation requirements. This required a large amount of research and liaising with interested parties and government departments.

 

This findings of this report will underpin the development of the preferred power project which will meet the needs of the dynamic East Kimberley region.

 

QLD Department of Energy – Queensland Energy Policy – Modelling of Policy Proposals – January to April 2005

ROAM Completed a detailed assessment of the possible development opportunities for the Queensland region under a number of policy proposals with a focus on CO2 emissions and cost of mitigation. This assessment was completed by employing Integrated Resource Planning to establish the least cost generation development path for the Queensland region under varying conditions, policies and carbon tax regimes.

 

Western Power – Assessment of SWIS Reliability for 2004-05 – July 2004

A detailed assessment of generation reliability within the South-West Interconnected System (SWIS) of Western Australia was completed. For this assessment ROAM developed a market model of the SWIS from a range of data sources in a very short time frame. The assessment established the minimum reserve level requirement for the SWIS to deliver adequate reliability for the power system. Western Power subsequently installed short term backup supply for the summer period which enabled them to meet the peak power demand without loss of supply.

 

NEMMCO – Review of Reserve Margin Requirements for Queensland and New South Wales including a full NEM review of Reserve Margin Requirement and the Effect of Demand Diversity on Reserve Level Requirements in Each Interconnected Region – January to July 2004

This review required detailed generation forecasting and reliability analysis including increased usage of the application of dynamic transmission limits and transmission forced outage analysis in the 2-4-C software package. This assignment involved significant statistical analysis of generator reliability indices and load trace forecasting methodologies to assess the interactions between regions in the NEM system under various demand and weather scenarios. The culmination of this work was subsequently employed by NEMMCO to apply the reserve level requirements within each region of the Australian NEM for system security within their market dispatch systems.

 

NEMMCO – Review of Reserve Margin Requirements for South Australia and Victoria – December 2003

Provided detailed generation forecasting and reliability analysis including application of dynamic transmission limits and transmission forced outage analysis within the 2-4-C software package. This assessment formed the first review of the NEM Realibility Standard to calculate Minimum Reserve Levels since the NEM was formed in 1998. The recommendations of the study were subsequently endorsed by the NEMMCO board resulting in a change to the Victoria and SA region minimum reserve levels.

 

CS Energy – Intra-regional Constraints Issues Paper – June 2003

This theoretical paper addressed the following topics:

1. An introduction to Constraint Equations and how they are determined
2. An introduction to Limit Equations
3. Steps in formulating Limit Equations, including :
1. Selection of parameters
2. Converting curves to linear functions, and
3. Tolerances applied to the limits subsequent to the calculation of the parameters
4. Further consideration of the coefficients provided in the published constraint equations and the likely tolerances on these
5. The application of transmission limits on generation dispatch particularly on the ‘upstream’ side of transmission limits.
