Prior to the start up of the standard market design (SMD-2), the New York independent system operator (NYISO) used various tools to maintain and update three network models used to support the energy management system (EMS) and business management systems (BMS) applications. The process of maintaining and updating the network models for EMS & BMS applications became more challenged and cumbersome for our engineers to support. These challenges are becoming more relevant as the NYISO grids are becoming more congested with rapidly changing power flow patterns responding to market conditions. The NYISO's network models cover the entire New York state with about 3100 buses, 30/70 split between internal/external and 40 AGC tie lines to other ISOs such as PJM, ISONE, IMO & HQ and all the 69 kV and above systems. Currently, there are eight transmission owners and 400 plus market participants that participate in our markets. As part of the SMD-2's requirements, which were successfully implemented in December 2005, the NYISO consolidated all the SCADA, EMS & BMS applications to run under one single platform and that is ABB's Ranger Systems. To maximize the convergence and improve the solutions between the SCADA, EMS and BMS applications, network models for various applications on different platforms were also consolidated into a single model and that in turn drives all the applications including the dispatcher training simulator.
