Abstract

A decision-support tool is provided to evaluate operational and financial performance for dispatchers in power grid control centers associated with utility systems. A scheduler engine is coupled to a comprehensive operating plan that applies after the fact analysis for performance metrics, root-cause impacts and process re-engineering. A relational database is coupled to a data archiver that captures actual system and resource conditions and then supplies the system and resource conditions to the relational database. The scheduler engine receives the actual system and resource conditions from the relational database and processes it to calculate system performance. A user interface is configured to display at least one of, transmission evaluation application displays, reference and scenario cases and associations between them, results presented with a graphical or tabular displays, comparison results between scenario cases and a reference case, a family of curves where each curve is a performance metric, comparison of scenario input data, study results and statistical analysis and historical data.
