The DSI State estimator (DSI-SE™) Is Integrated with the EPRI OTS and EPRI STEMS

The DSI State Estimator (DSI-SE™) was integrated to the EPRI-OTS via a Common Information Model (CIM) interface. This program which was based mainly on Dr. Debs’ research in the state estimation and bas-data detection areas (See Chapter 8 of Dr. Debs’ book, "Modern Power Systems Control & Operation: A Study of Real-Time Control of Power Systems). The implementation of the software was carried out by Dr. Charles Hansen, Senior Consultant, DSI. This version of the OTS will allow users to work in a realistic environment whereby they will be exposed to the estimated values of measurements and state variables. Effort is underway to develop training scenarios using this new capability and also for training users on the state estimation application in the control center. The DSI-SE is capable of detecting and correcting multiple bad data points in the system and uses a very robust algorithm for the estimation process.
