Abstract

The Electric Reliability Council of Texas (ERCOT) is certified by the Public Utility Commission to functions as an independent organization, and ensures the reliability and adequacy of the regional electrical network. It has implemented a dynamic ratings application (DRA) into its energy management system (EMS) improving the economic efficiency of the market by reflecting the change in ambient weather conditions on the ratings of transmission service providers (TSP). The DRA runs every five minutes to update real-time ratings and using a static table when its input consists of temperature from a TSP or ERCOT. The range of temperature points is in increments of 5 °F and ranges from 20 °F to 115 °F and for each temperature point, a normal rating, an emergency rating and a 15-min rating are available. The DRA provides the information of the dynamically rated elements such as the element ID with normal, emergency, and 15-minute ratings the TSP, the related substations, and the geographical location of the weather station.
