Abstract
- In recent years constraints forced by the environment, right of way and energy costs have resulted in power systems operating with considerably reduced stability margins. Consequently, modern power systems depend strongly on stabilizing devices to keep reliable and stable operation. These devices should provide sufficient damping in the system, during the transient period following a system disturbance, such as line switching, load changes and fault clearance. To avoid collapse of the system due to loss of synchronism or voltage instability, countermeasures such as power system stabilizers, optimal turbine governor control systems and phase shifters have been used. This concept presents the transient stability analysis of a power grid, which integrates both Superconducting Magnetic Energy Storage (SMES) and Gridable Vehicles (GVs). Also, Vehicle-to Grid (V2G) operation is devised to control GVs to charge power from or discharge to the grid. SMES and GVs to adjust the active power and reactive power to support the System. Simulations of both balanced and unbalanced faults such as 3LG fault, LG fault, LLG fault are carried. The system model is established and simulated using the Matlab/Simulink. The results of load angle response and system voltage response are given to illustrate that both SMES and GVs can enhance transient stability of the power grid. Moreover, the simultaneous use of SMES and GVs can further improve the system dynamic performances. [ABSTRACT FROM AUTHOR]
