Security constrained optimization: an added dimension in utility systems optimal power flow

The concept of optimal power flow (OPF) is defined, and security-constrained OPF (SCO) is described. Two examples are presented to show how the SCO program provides enhanced capability for the utility engineer in solving problems. One deals with VAr support for transmission system expansion, and the...

Description
Summary:The concept of optimal power flow (OPF) is defined, and security-constrained OPF (SCO) is described. Two examples are presented to show how the SCO program provides enhanced capability for the utility engineer in solving problems. One deals with VAr support for transmission system expansion, and the other concerns substation capacitor bank location.< >
