REAL-TIME UPDATE OF POWER SYSTEM MODELS FOR DYNAMIC SECURITY ASSESSMENT

Provided is a system and method for updating dynamic power system models during each DSA analysis cycle. In one example, the method may include iteratively executing a dynamic security analysis (DSA) on a power grid based on a simulation of a dynamic power system model, receiving measurements from one or more sensors on the power grid, modifying one or more parameters of the dynamic power system model used in a previous iteration of the DSA based on the received measurements, simulating the modified dynamic power system model, determining a security value of the power grid during a current iteration of the DSA based on the simulated modified dynamic power system model, and storing the determined security value in memory.
