Abstract
SUMMARY
The paper presents steady-state and transient studies to assess the impact of connecting the world’s largest photovoltaic (PV) park at Benban to the 500/220 kV interconnected transmission system of Egypt. Three scenarios are considered to connect the Benban PV Park to the Egyptian grid: Scenario 1 is the connection to the grid at both 500 and 220 kV levels, Scenario 2 is the connection to 220 kV level only and Scenario 3 is the connection to the 500 kV level only. The DIgSILENT PowerFactory professional software is used to simulate the system and to obtain the results in all scenarios. The results include percentage of transmission line loadings, busbar voltages, (active and reactive) grid losses, in addition to 3-phase fault and 1-phase fault levels. Also, simulation studies have been performed to assess the transmission system transient responses to Benban Park full outage. Voltage deviation index is also calculated and compared in all scenarios.
The simulated Egyptian grid includes the 500/220 kV grid with existing generating plants, in addition to the world’s three largest combined cycle power plants, of 4800 MW each, (recently commissioned at Beni Suef, Burullus and New Capital), the world’s largest photovoltaic power park of 1800 MW which is under construction at Benban and the 540 MW Gabalzeet wind farms. The results have shown that the best choice is to connect Benban PV Park to the grid at both 500 kV and 220 kV levels.
