The Dynamic Behavior of Large Scale Safawi PV plant integrated to the National Transmission Grid of Jordan, Particularly 132 Kv Busbar

The objective of the transient stability studies is to verify the compliance of the performance of the proposed (PV) Photo Voltaic plant power system design, without reactive power compensation, with the( NEPCO) National Electric Company (GCC) Grid Code Compliance requirements of Low Voltage Fault Ride Through (LVFRT), High Voltage Fault Ride Through (HVFRT), and dynamic voltage control abilities specified for the connection of the 50 MW projected Safawi PV plant to the NEPCO system. The present paper introduces a complete study of dynamic behavior of large scale PV plants integrated to the power grid. The DIgSILENT power factory software is used to model the national transmission grid of Jordan. Three-phase short circuit calculations were performed and analyzed for the grid with Safawi PV plants. It was found that the projected PV plants to be connected in the period of (2015-2020) are complied with the LVRT and HVRT characteristics of the GCC except 3 cases, when the installation of (SVC) Static Var Compensation is required. Voltage profiles of Safawi PV plants that will be connected to the grid during the period of (2015-2020) is complied with the LVRT and HVRT characteristics of the GCC except for cases 4, 6 and 7.For these cases, it is required to install SVC, in order to provide the required steady state and dynamic voltage support. Another option is to change the projected capacity of the PV plants.
