Abstract: Adopting local parameterized continuous trend method and bifurcation theory, this paper studied the optimal installation location of static var compensator (SVC) in AC/DC interconnected system. Taking the WSCC9 node test system for example, by tracking the epidemic curve of the system equilibrium solution and searching the bifurcation point of system stability limit, the more sensitive bus to insufficient reactive power compensation was obtained in the system. And the voltage stability of the whole AC/DC system at a bus node was improved to realize the compensation of the system reactive power in the most economic situation.
Key words: static var compensator; voltage stability; continuous trend method; bifurcation theory; installation position
