California ISO extends technology partnership with Siemens

The California Independent System Operator Corporation has extended its technology partnership with Siemens to now include real-time contingency analysis software in addition to Siemens’ energy market management system to support the growing ISO full network model, which provides a detailed and accurate representation of the power system.

The expanded full network model ensures the California ISO has a more accurate assessment of real-time system condition for its area.

The contingency analysis software, a component of the Siemens Spectrum Power transmission network applications, currently simulates more than 2,000 separate equipment failures in the ISO footprint and its neighboring areas every two minutes and alerts the system operator to potential issues.

With this detailed insight, the ISO will now be able to identify potential transmission system problems sooner, which allows grid operators more time to take preventive actions in order to ensure reliability.

The real-time contingency analysis system is configured currently to support up to 10,000 contingencies simulation every two minutes. It can easily scale and support a much larger number of contingencies and/or shorter cycle times if necessary to support the continued expansion of the ISO’s full network model.
