As with biomass, hydro, solar and wind power, fusion power can also generate clean energy, using deuterium, an isotope of hydrogen, abundantly available in our oceans. Our sun uses hydrogen in a fusion process to generate power. It has been demonstrated that fusion power can be generated on earth, under carefully controlled conditions using deuterium and tritium instead of hydrogen. There are two fundamental approaches to controlled fusion: magnetic confinement fusion (MCF) first proposed at Princeton University in 1951, and inertial confinement fusion (ICF) that followed shortly thereafter, first proposed at the Lawrence Livermore Laboratories in 1970. Progress made on magnetic fusion led to the planning and construction of ITER (International Thermonuclear Experimental Reactor), expected to be completed in 2035. In this article, we explain the processes necessary to generate fusion power through MCF and ICF. Unlike nuclear power, as a practical means to generate electricity, controlled fusion has presented the technical/scientific community with a plethora of very difficult challenges. It is only recently, after decades of intense research in many laboratories worldwide, that we have begun to see devices being built on a fusion reactor scale and hence the design of ITER. The challenges are many but require patience and perseverance.

This paper presents a new method of predicting power based on predictive direct power control. This method reduces power ripple in a doubly fed induction generator, which makes it possible to have a smoother synchronization with the grid in low constant frequency switching. To achieve fast and smooth grid synchronization without any over current, the difference between the measure, frequency, and the phase of the stator voltage and the grid voltage should be minimized. This condition can be achieved by minimizing the error between active and reactive virtual power and their references. By predicting the virtual active and reactive power behavior and choosing different active voltage vectors and using each of them at different times among each period time, the best switching of the rotor side converter in doubly fed induction generator to have a smoother condition can be chosen. In this paper, a 15kw generator is simulated by the classic method which is direct power control, and this new method, predictive direct power control, and it will be shown how much the new method reduces the power ripple to have a smoother synchronization that doesn’t cause mechanical or electrical pressure for none of the grid and the doubly fed induction generator.

Nearly two billion peoples in developing countries do not have access to electricity service. Renewable energy resources are a best option for rural electrification in a country like Ethiopia where electric light is a luxury enjoyed only by a few peoples. Nowadays, only around fifteen percent of the populations living in urban and semi urban areas are connected to the national grid. The remaining populations are living in scattered rural villages and have very remote chances to get electricity from the grid. The only realistic approach to electrify the rural areas seems therefore to be the off grid or self-contained system. The contributions of renewable sources of energy like micro/mini or Pico hydro power, to rural electrification are minimal still. The main objective of the present study was to identify the potential of mini hydropower site and proposing a plant for rural electrification in Keber River around Tobacha kebele. So in the research the study starts from the estimation of the design discharge by analyzing of the stream flow using the flow duration curve. For estimating the design discharge the available discharge in the river, the population demand and some guidelines for development of mini hydropower were used. So using the above constraints the power of 120kw was designed for a 300 households, 1 clinic and 2 elementary schools. Besides estimating the power, the present study focuses on design of civil structures and selection of electromechanical components. Generally the result of the study shows that construction of mini hydropower was feasible in the project site.

In an energy environment with multiple production sources, operators are generally confronted with the optimal choice of sources which minimizes polluting gas emissions, losses and marginal production costs while meeting the contractual requirements for maintaining voltage in the ranges required. The present work consisted of optimizing an energy mix in the presence of multi-STATCOM in an interconnected network. Indeed, the (DEE) is a concrete real time problem in electrical energy production systems. This paper shows the impact of STATCOM on static DEE (DEES) and on dynamic DEE (DEED) using the modern genetic algorithm of type U-NSGA-III, which is based on non-dominance sorting. The optimal positioning of two STATCOMs in the application network associated with dynamic dispatching has contributed to the reduction of the total production cost, toxic gas emissions, active losses and then to the improvement of the voltage profiles and the transit of power in the branches. It is observed that the combination of DEED with the optimal positioning of FACTS in an interconnected network constitutes an efficient technico-ecological means to act in the direction of reduction on the triplet consisting of (gas emissions, losses, production cost). The relevance of the results obtained compared to the real case of operating the CEB's interconnected network, justifies the performance of the algorithmic tools developed in the context of this work.

The electrified railway systems have been spreading all over the world. In big cities, metro or light rail transit railway networks have been constructed extensively. Expansion of this enormous dynamic electric load has been created huge amount of stress on the power grid. Generally, the speed drives, power conversion equipment or frequency converters inject harmonic in to railways power supply system. These harmonics seriously disturbs other electrical systems or generate a high frequency electromagnetic fields in neighboring electrical equipment as well as traction network signaling system. However, new developments in power electronic converter enable efficient and flexible conditioning of electrical energy in the application of railway power system. Power electronics, already previously being a pioneer for progress of traction vehicles, brought forth an ultimate standardization of the traction power supply system. Today, the spectrum of power electronic converters application in the traction system spread in many areas including power electronics based traction transformers, auxiliary power supply systems, rectification, integration of regenerative braking, reactive power compensation and voltage regulation and traction motor controls. This paper reviews the applications of semiconductor based power electronic devices in electrified railway system and illustrates some major application areas.

Dye-sensitized solar cells (DSSCs) enticed the attention in photovoltaic design due to their unique features of ease of fabrication, low-cost materials, tunable color, and flexibility. In this work, we studied the performance of a low cost dye-sensitized solar cell structure with several natural dyes as a sensitizer. Titanium dioxide (TiO2) was used as the semiconducting layer. The TiO2 film was fabricated on Florine doped Tin Oxide (FTO) glass plate and was annealed and sintered for an hour at 450°C temperature to create a mesoporous layer. To reduce the manufacturing cost, we used Carbon black instead of Platinum (Pt) as a counter electrode. Carbon black provides excellent stability and shows high catalytic ability along with its low cost as the counter electrode in the DSSCs. Eight different dyes have been extracted and purified by Silica gel column chromatography to use in the DSSCs. UV-Visible absorption spectroscopy and fluorescence spectroscopy has been done to measure the absorbance coefficient and fluorescence coefficient of each of the cells. The cells with an additional peak in the fluorescence spectra showed much better electrical performance compared with others. Among the fabricated DSSCs, the Curcuma longa based DSSC gives the highest open-circuit voltage of 0.5959 V and short circuit current density of 1.06 mA/cm2. The study also indicates that the dyes with a peak at 380 nm to 400 nm wavelength at fluorescence spectrum has better photovoltaic performance rather with a moderate absorbance spectrum.

Today, utilities are trying to maximize system reliability, improve efficiency, and reduce costs by using protection system, distributed generation system, by reconfiguring the feeder, by connecting the end of feeder to other substation and so on. However, when it tries to use some techniques (reconfiguring the feeder, connecting the end of the feeder to another substation); the techniques have positive and negative impact on reliability improvement. The substation which is taken in this paper has the System Average Interruption Frequency Index (SAIFI) and System Average Interruption Duration Index (SAIDI) is 521.46 interruptions per customer per year and 446.82 hours per customer per year respectively. The historical outage interruption data of the years of 2016-2018 has been used as a base year. The study has evaluated the new substation to improve the system reliability. The simulation results have been done with the help of Electrical Transient Analysis Program (ETAP 12.6) software. In this paper includes improvement of the system reliability of the feeder is supplied from two substations or new substation should be connected at the end of the feeder. Due to the new substation, the length of the feeder will vary, and the variation of the feeder has significant effect on power reliability. The value of SAIFI and SAIDI after the new substation connected is 169 and 96 respectively. Since the new substation has negative impact, the value of indices is not reduced more.
