Abstract: The energy generated by the force of water can provide a more sustainable, non-polluting alternative to fossil fuels and other renewable energy sources, including wind, solar, tidal, geothermal, and bioenergy. Micro hydropower is hydro energy on a small scale and provides hydromechanical and hydroelectric power to small communities. This study aimed to conduct technical assessments of the micro-hydropower potential of generating hydroelectric and hydro mechanical power from existing irrigation schemes in West Shewa and East Wollaga, Oromia. From the two zones, 16 schemes from the East Wollaga Zone, and 5 schemes from the West Shewa Zone were selected; all of these schemes had the potential for irrigation and were functional. Out of 8 districts, 21 irrigation schemes were technically assessed. Among the analyzed schemes, the maximum Hydraulic power potential for micro-hydropower generation at 80% efficiency was 14.27 kW at the Chaka Arba scheme in the Wayu Tuka district and 5.95 kW, 5.35 kW, 6.54 kW, 5.4 kW, 5.35 kW, and 6.5 kW at Jalale, Gindo, Indiris, Laga Dabesa, Molo, and Sako schemes of East Wollaga Zone, respectively. The maximum discharge recorded was 1.429 m3/s at the Chole 3rd scheme in the Toke Kutaye district in the West Shewa zone. Generally, some of the assessed schemes are insufficient for micro-hydro power generation in the West Shewa zone. However, some of them are possible with technical advances for Pico-hydropower and micro-hydropower.

Abstract: This paper introduces a fuzzy logic-controlled power system stabilizer to improve the transient stability of Tana Beles Hydro power plant during faulty conditions. The power system stabilizer is integrated into the generator excitation system to enhance the damping effect during low frequency oscillations. To achieve better transient stability, the acceleration and rotor speed deviation of the synchronous machine are used as inputs to the fuzzy logic controller. These variables influence the control of the damping in the generator's mechanical shaft. The designs of system controllers are directly connected to the excitation systems of the plant under wide operating conditions. The system performance has been performed in different scenarios with conventional power system stabilizer (CPSS), PID controller, and fuzzy logic-based power system stabilizer (FLPSS). FLPSS improves settling time of rotor speed, load angle, active power and electrical torque of the plant by 42.9%, 16.7%, 29.2% and 35.7% respectively, over CPSS. Similarly, the system controller improves the settling of rotor speed, load angle, active power and electrical torque of the plant by 33.3%, 9.5%, 29.2% and 25% respectively, over PID controller. The comparison was made between Conventional power system stabilizer (CPSS) and PID controller with Fuzzy logic-based power system stabilizer. The control techniques are simulated over the power transmission single line diagram of Tana Beles Hydropower plant under different scenarios using MATLAB/Simulink software.
