Abstract

A method is provided for evaluating operational and financial performance for dispatchers in power grid control centers associated with utility systems. A comprehensive operating plan is provided that applies after the fact analysis for performance metrics, root-cause impacts and process re-engineering. after the fact analysis of past events and practices is performed. Actual system and resource conditions are captured. the system and resource conditions are supplied to a relational database. A scheduler engine receives the actual system and resource conditions from the relational database and processes it to calculate system performance. At least one of the following is displayed, 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.
