Determination of location and amount of series compensation to increase power transfer capability

This paper discusses the merits of an analytical method for determining the location and amount of series compensation to increase the steady state power transfer capability in the power system based primarily on cascading line overload considerations. Steady state transmission limits define the boundaries of a power system operating point. This paper presents tools to identify these boundaries and analytically estimates the change in the boundary limits due to the application of series and shunt compensation. The approach identifies critical lines that can 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.
