Abstract:
ABSTRACT Understanding how to use water resources in a sustainable manner and projecting the climate systems pattern under different climate scenarios can assist planners on how to mitigate and adapt to the multi-dimensional impacts of climate change. Omo- Gibe River basin is one of the areas with the highest potential for socio-economic development due to the tremendous potential for hydropower and irrigation. However, in recent years, climate variations have induced hydrological variability posing a challenge for decision-makers on how best to plan, design and operate hydropower plants. Hence, there is a need for better models to forecast which systems can lead to a sustainable and optimal power generation. The main goal of this study was to synthesize and understand the extent of climate change impact on the generation capacity of the cascade hydropower plants as well as proposing an adaptive way of operating hydropower instead of traditional approach that uses conservative rules in the Omo-Gibe River Basin. An attempt has been made to collate historical and future projected climate data under different climatic scenarios from different sources. After applying Rulebased Simulation (RBS), on the Omo-Gibe River basin with a catchment area of 79,000km2, results showed there is substantial impact on hydro-energy generation due to climate change which can influence long term investment and the generation capacity of cascade hydropower plants across the basin. Moreover, after applying an optimization that used a Linear Goal Programming (LGP) and post- Optimization Rulebased simulation (PORBS), it was possible to bring the operation of cascade hydropower system into optimal state which implements dynamic and adaptive operational policies. Keywords: Climate Change Impact, Rulebased Simulation, Optimization, Hydropower Operational Planning
