generating units with optimized short-term generation schedules
transitions while maintaining optimal dispatch
water regulation requirements satisfied
- The New York Power Authority needed to replace the legacy short-term scheduling software used at its St. Lawrence project.
- The software had to work within the constraints of shared water-resource regulations between Canada and USA.
- Water releases had to be perfectly balanced between the Canadian and American plants on a daily and weekly basis.
- ST Vista, the short-term scheduling module of Hatch's Vista DSS™ decision-support software, will optimize short-term generation at NYPA's St. Lawrence power project.
- New functionality was developed in the form of additional operating constraints and run-control options.
- The software manages water rentals between both plants; implements multiple schedules for flat, daily peaking or weekly ponding operation; and transitions between non-navigation and navigation seasons.
- A custom user interface was also developed to simplify the use of the model for day-to-day operation within the control room environment.
- Reduced the number of transitions, such as unit starts and stops, while maintaining optimal dispatch.
- Significantly strengthened automated data exchange between the scheduling software and other NYPA systems.
- Improved overall effectiveness of the scheduling process.
