Abstract

This paper presents a new power system planning tool, called the transmission and voltage limitation (TVLIM) program, which provides a graphical display of the set of all feasible and secure interarea megawatt power transfers. The TVLIM program identifies the voltage magnitude limits, thermal loading limits, and voltage stability limits that constrain power transfer between areas. These limits define the boundary of a security region, called the TVLIM region, in the space of area imports of real power. Two TVLIM regions are generated, one for the base case operating condition and the other for the next contingency set. The next contingency TVLIM region identifies the limiting contingencies in addition to the weak links in the power network. A 39-bus and a 300-bus test power system are used to illustrate the TVLIM display
