“…The discussions indicate that regions with relatively weak natural energy may be developed by applying the microgrid with possible compensation between micro-sources. The study in [17] examines the feasibility of applying a micro hydro power generation system in a microgrid as part of the various regional energy programs underway in Africa. It also points to R&D advancements in various technologies focused on energy sustainability and suggests that micro hydro power generation systems integrated even at microgrid powered levels have potential to provide an efficiency of service to rural communities and can serve as primary building blocks for future system expansion.…”

The significant benefits associated with microgrids have led to vast efforts to expand their penetration in electric power systems. Although their deployment is rapidly growing, there are still many challenges to efficiently design, control, and operate microgrids when connected to the grid and also when in islanded mode, where extensive research activities are underway to tackle these issues. It is necessary to have an across-the-board view of the microgrid integration in power systems. This paper presents a review of issues concerning microgrids and provides an account of research in areas related to microgrids, including distributed generation, microgrid value propositions, applications of power electronics, economic issues, microgrid operation and control, microgrid clusters, and protection and communications issues.

“…A vast majority of the people in developing countries, especially in rural areas, do not have access to electricity (IEA 2015, Shezi 2015, Yuksel et al 2013, Sambo 2005). This number keeps increasing despite the rural electrification programs because they are not sufficient to cope with the population growth or the political will in some of the places is not strong enough or absent (Omprasad 2016, Adejumobi et al 2013, Wang 2009. Moreover, despite the fact that about 80% of the world"s population lives in developing countries, they consume only about 20% of the global commercial energy.…”

“…There are many sites suitable for Pico hydro development in Nigeria as in many other African countries. Pico hydro has made some in roads in sub Saharan Africa as well, where electrification rates are some of the world"s lowest (Wang 2009). However, focus has not been given to it as part of frantic efforts to combat the energy crisis (Bala 2013b, Ajuwape andIsmail 2011).…”

Mission ATINER is a World Non-Profit Association of Academics and Researchers based in Athens. ATINER is an independent Association with a Mission to become a forum where Academics and Researchers from all over the world can meet in Athens, exchange ideas on their research and discuss future developments in their disciplines, as well as engage with professionals from other fields. Athens was chosen because of its long history of academic gatherings, which go back thousands of years to Plato's Academy and Aristotle's Lyceum. Both these historic places are within walking distance from ATINER"s downtown offices. Since antiquity, Athens was an open city. In the words of Pericles, Athens"…is open to the world, we never expel a foreigner from learning or seeing". ("Pericles" Funeral Oration", in Thucydides, The History of the Peloponnesian War). It is ATINER"s mission to revive the glory of Ancient Athens by inviting the World Academic Community to the city, to learn from each other in an environment of freedom and respect for other people"s opinions and beliefs. After all, the free expression of one"s opinion formed the basis for the development of democracy, and Athens was its cradle. As it turned out, the Golden Age of Athens was in fact, the Golden Age of the Western Civilization. Education and (Re)searching for the "truth" are the pillars of any free (democratic) society. This is the reason why Education and Research are the two core words in ATINER"s name.

A study to determine the influence of penstock outlet, number of v-blades, flat blade lateral twist angle and the hub to blade ratio on the performance of the Pico-hydro system has been conducted. Five turbine runners with 8, 9, 10, 11 and 12 v-blades were fabricated and tested on an already existing system. A runner with adjustable flat blades was also fabricated and tested for twist angles of 50 0 , 55 0 , 60 0 , 75 0 and 90 0. Runners with v-blades but having hub to blade ratios of 0.3, 0.4, 0.55, 0.65 and 0.7 were also tested. The turbine was connected to 3.9 kVA alternator via a v-belt drive and a 1 Hp pump was used to sustain the flow. The turbine and alternator shaft speeds were measured, and the level of water in the overhead and underground reservoirs monitored. The flow rate, available head and the hydraulic power were computed for each operation. The results obtained indicated that using a combination of a runner with 12 blades and a penstock outlet of 20 mm, 0.55 hub to blade ratio and lateral twist angles greater than 75° combined with penstock outlets larger than 20 mm have the potentials of better performance in terms of power generation. The results of correlation and reliability test using Cronbach's alpha carried out on the data at 95% confirmed these findings. This will be very useful for further development of the system in order to attain implementable status as a clean and decentralized energy source.
