Use of a grid operator training simulator in testing new real-time market of California ISO

This paper describes the challenges faced by the California ISO in testing the integration of the new California real-time nodal market with the energy management system. The paper addresses how an operator training simulator was used for testing the real time market and some critical functions of EMS. CAISO´s EMS dispatcher training simulator was modified and coupled with CAISO´s market applications to act as a real time market and grid operation simulator. This new simulator provides realistic behavior of the physical network of California ISO grid in response to the instructions from the real time market.
