Abstract
Hydro power plants have been a major source of energy over the years and there have been series of improvement from micro units to large scale units. Irrespective of the great milestones achieved in generation of electrical energy through hydro power plant, there have also been challenges confronting these means of power generation amidst which include voltage and frequency instabilities. This research work used fuzzy logic control algorithm in order to contribute to Micro Hydro Power Plants stability and dynamic performance improvement. Its effectiveness was shown through a comparative analysis to Conventional Controllers simulated in Matlab/Simulink 2018a. Both controllers were subjected to dynamic performance tests in order to evaluate their respective transient, performance stability and robustness responses in a designed Micro Hydro Power Plant. Results revealed that Fuzzy Logic Controller reduces the response time from 8.23s to 3.32s (improvement of 4.91s averaged over all conducted tests) and provides smaller overshoot with a reduction from 49.65% to 35.54% (improvement of 14.11% averaged over all conducted tests). These results show that Fuzzy Logic Controller has significantly improved the stability and the dynamic performance of the considered Micro Hydro Power Plant.
