Teshmont’s team has approximately 40 years of experience in addressing issues related to power system losses, and have been assisting the Alberta Electric System Operator (AESO) on loss-related matters since 2004.
Among the tools at the AESO’s disposal for accomplishing its objectives are economic incentives, one of which is a system for allocating the locational costs of losses incurred in the transmission of power produced by each generator to that generator’s owner.
In any power system, there is a disparity between the amount of power that is generated or imported, and the amount of power that is used by loads or exported. The difference is accounted for primarily by transmission loss; energy that is expended heating transmission lines and other transmission elements, or is lost in other forms such as corona when power is transmitted from source to its destination.
The AESO commissioned Teshmont to research available methodologies for loss factor calculations, to recommend the most suitable, and to provide a system for the calculation of loss factors including purpose-written software that could be used easily and efficiently by engineers at the AESO to determine each generator’s impact on losses.
After establishing a methodology, Teshmont developed a production software tool for the new loss factor methodology. Python, as a programming language, was used extensively in development of the Graphical User Interface (GUI), because of its ability to interact seamlessly with PSS®E software.
Teshmont’s specialists have also provided expert technical witness services on behalf of the AESO. Teshmont provided written and oral testimony, information responses, and responses to undertakings, intervener interactions, and responses to questions from other parties.
