Abstract
Volume 1 comprises Module 1 (Power Study) that incorporates several documents:
1: 2015 “ Power Study
The report presents the studies of the anticipation of the interconnection between Ethiopia and Sudan in 2015 for the peak load scenario in: permanent state (normal and N -1 situation); short circuit power; and dynamic study.
1: 2020 Power Study
For the peak and intermediate load situation in 2020/2021, this report presents the studies for the three countries interconnected system in: permanent state (normal and N-1 situation); short circuit power; and dynamic study.
2025 – Power Study
To demonstrate that it was possible to export some 3,200 MW from Ethiopia to Sudan and Egypt, the operation of the interconnected system was simulated in year 2025 for the period of the annual peak load demand (simulations carried out in permanent and transient states).
2030“ Power Study
This report presents the studies for the three countries interconnected system for the peak load situation in 2030 in permanent state, short circuit power and dynamic study.
1: 2030 Target Network
This document provides the 2030 networks for each of the 3 countries: Egypt, Ethiopia and Sudan. The proposed expansion plan for the countries’ systems comprises demand scenarios, generation expansion plans, generation/demand balance, hydro-power connection schemes, and transmission expansion plans.
M1: DC Link Optimization
The DC link considered for the study is the transmission line between Kosti (Sudan) and Nag Hammadi (Egypt). The optimization study involved selection of the DC voltage and cross-section of conductors of the DC interconnection. The optimization is based on an economic comparison between different solutions for DC voltages, HVDC stations, and overhead line conductors.
Notes: i) Concerning the network, the study was based on the data collected in Phase I, and updated during a meeting held in Phase II; ii) Regarding the demand and the generation expansion plan, input data are the results of the economic study performed in Phase I.
