Optimal Power Flow with Transient and Voltage Stability Considerations Using Evolutionary Programming
This paper develops an evolutionary programming (EP)-based method for solving optimal power flow (OPF) with transient and voltage stability considerations. The transient stability issue is addressed by adding the swing equation and transient stability limit into the OPF constraint whereas the voltage stability issue is addressed by adding the steady-state voltage stability indicator L into the conventional OPF objective function. It is assumed that the indicator L at the weakest bus represents the steady-state voltage stability of the whole system. A three-phase fault at a specific transmission line is considered as a single contingency for transient stability issue. The IEEE 30- bus system is used as the test system to demonstrate the effectiveness of the proposed method. Two types of cost curves are considered to represent convex and non-convex objective functions. The results show that the OPF considering both transient and voltage stabilities can provide a transiently stable operating point with high voltage stability margin. In addition, its results are compared with those of the conventional OPF and OPF considering either transient or voltage stability.
