Abstract

The capability of controllable shunt and series compensators to modulate the real power flow in integrated AC/DC systems has been investigated and compared. The linearized state space equations of the system have been included in a load flow program and the change of the real power flow per change of the reactive or both active and reactive power in the compensating equipment has been calculated in specified locations of the system. This investigated capability of the controllable compensators depends on the kind of compensator connection (series or shunt) and the basic variables of the system it influences and it is not related to the technical problem of exploiting this capability. The influence of the load and compensator location, the load characteristics and the equivalent system impedance on the power flow control effectiveness has been presented and commented on for a test system
