Many uses of AC Optimal Power Flow in the Changing Industry

This session concerns potential often hidden benefits from using AC OPF in support of reliable, resilient and efficient decarbonization. We discuss its use for enabling system operators and planners to identify the main constraints which cause AC power flow to fail, and to suggest the most effective on-line adjustments and/or longer term system enhancements. This is needed when typically used DC tools (DC power flow, DC OPF) lead to failures to balance reactive power and/or to maintain voltages within the acceptable limits. In other words, AC OPF can be used to extend power transfers without experiencing voltage collapse. As such, it support utilization of existing thermal transmission system capacity more efficiently. Instead of simulating effects of adjustments made by system operators and/or off-line worst-case studies, an AC OPF can be used to identify the best adjustments. We further present how a computationally robust AC OPF can be used for many planning, operation and market purposes.
