Abstract
There is provided an optimization model and methods for quick track of a Static Voltage Stability Region (SVSR) boundary of a power system. The methods include using a base power flow as a starting point to track a first power system SNB point by a traditional OPF and mapping the SNB point to obtain an SVSR boundary point, and includes repetitively changing a power stress direction to a new direction and tracking a power system SNB point in the new power stress direction and mapping the power system SNB point to obtain a new SVSR boundary point, and includes returning to the first power system SNB point if the power stress direction angle is ≤0; repetitively changing the power stress direction to a new direction and tracking a power system SNB point and mapping the power system SNB point to obtain a new SVSR boundary point.
