DETERMINATION OF LOCATION AND AMOUNT OF SERIES COMPENSATION TO INCREASE POWER TRANSFER CAPABILITY

This paper discusses the merits of an analytical method for determinin g the location and amount of series compensation to increase the stead y state power transfer capability in the power system based primarily on cascading line overload considerations. Steady state transmission l imits define the boundaries of a power system operating point This pap er presents tools to identify these boundaries and analytically estima tes the change in the boundary limits due to the application of series and shuns compensation. The approach identifies critical lines that c an initiate cascading line outages and identifies the optimal location and amount for series compensation. The methodology can also be used to select sites for devices that can extend the availability of power in flowgates.
