Abstract: Use of micro hydropower plants is an ideal method of providing power for off-grid rural communities especially in developing countries like Ethiopia. In Ethiopia only 8% of the rural community has access to electricity, and the power supply in the country is very low as compared to its population growth. The present study assesses the technical and socio economic aspect of water mill sites in North Shoa zone of Amhara regional state, Ethiopia for the development of micro hydro power plant. Through technical assessment of the flow rate measurement, head measurement and estimation of power generation potential of the mill sites has been done. The socio economic assessment was done by interviewing households, officials and mill owners. The results of the assessment shows that, out of the 14 mill sites investigated, 12 of them has the potential to generate power ranging from 5.52kw to 38.59kw with 80% efficiency during the dry season. It has been observed, the existing as well as former mill sites in North Shoa zone, are mostly located in the mountainous regions which offers an interesting opportunity for micro hydropower generation that would meet the energy demand of the villages at least 5km far from the main grid.

Abstract: Nowadays, the energy structure is gradually changing to clean power generation. Clean energy mainly includes renewable energy and part of non-renewable energy. Non-renewable energy is depleting day by day, showing a shrinking trend. Renewable energy is not affected by energy shortage, and is the focus of future development. How to ensure the sustainable and healthy development of clean energy, it is necessary to adjust the existing power generation energy structure scientifically and rationally. In this paper, the theory of hypergraph is introduced to cluster the optimal combination information of clean energy, and a hypergraph model of power generation energy structure adjustment is established. The problem of replacing fossil energy in power generation energy consumption with clean energy is solved as the original objective. By mapping the generation energy structure adjustment with hypergraph, the problem of generation energy structure adjustment is transformed into the problem of solving hypergraph path. By using the two-point hyperpath algorithm, an optimal path for the development of clean power generation, reducing the proportion of fossil energy power generation, and gradually converting to clean energy is obtained. The application of hypergraph algorithm in the structural adjustment of power generation is of great significance to promote the diversification of power generation energy, especially in the clean development, low-carbon development and green development of the power industry.
