Power Flow control in HVDC Grid and its effect on the system stability of underlying AC network

The share of Renewable Energy (RE) resources in overall power generation has grown over the years. Since these RE resources are located at places which are away (off-shore, desert) from the load centres, efficient and reliable power transmission to load centres is extremely important. High Voltage Direct Current (HVDC) transmission has evolved as the preferred efficient way to transmit large amount of power over long distances. It is proposed to interconnect HVDC transmission networks to form a HVDC grid for increasing efficiency and reliability. Since HVDC transmission is controlled by fast acting power electronic controls which have much faster response than conventional ac control, it becomes extremely important to study the effect of HVDC controls on power transfer with interconnected AC power systems so that both the systems operate in a robust stable condition. This project studies the effect of electro-mechanical oscillations due to power flow control on HVDC grid and its effect the stability of interconnected AC system.
