Risk-sensitive security-constrained economic dispatch via critical region exploration
A security-constrained economic dispatch (SCED) problem is regularly solved by system operators in electric power networks to make day-ahead and real-time dispatch decisions. Preventive SCED is conservative and requires dispatch decisions that are secure against any single component failure. …
