Transmission System Containing VSCHVDC Analysis and Simulation

The use of DC and especially VSC-HVDC systems are considered as urgent and important in electrical networks to improve their efficiency because they have great benefits not only in connecting different frequency networks and connecting the renewable energy to the network, but also control power flow in a way that reduce the losses and achieve the optimal flow electrical networks especially in networks that contain more than one energy supplier and thus can achieve economic benefits as well as the scheduling of importing energy from another that may improve network stability. Types of HVDC system and a comparison between them are achieved in this research after that simulation IEEE with VSCHVDC, and integrated computer program was proposed this program can create and store three-dimension matrix so the working area can be scanned so minimum loss working point can be detected.
