In this paper, a novel scheme is suggested for identifying the location of short-circuit faults that occur in distribution system. The proposed genetic algorithm and graph theory–based method is designed such a way that it splits electrical distribution system into protection zones containing buses, protection relays with measuring devices. Proposed methodology also decreases the calculation burden in dealing with large number of data sets. Genetic algorithm– based heuristic search method is used to place measuring devices at optimal location, and it is carried out in MATLAB. A new signal processing technique named dual tree complex wavelets transform is used for feature extraction, and support vector machine–based machine learning classifier is used for pattern recognition. IEEE33 bus radial distribution system and IEEE13 bus feeder test systems are tested for validating the proposed methodology and all the simulation work carried out in MATLAB Simulink.

Micro hydropower helps the rural areas to supply power with off grid electrification. This study deals with the design of micro hydropower scheme in Gobecho kebele, Genale Dawa river basin, Ethiopia. The site for the construction of diversion weir is located upstream of the Ganga river in the kebele. The design were implemented based on the available hydrological data collected from 1991 to 2020 river discharge at different stations by selecting the one, which is near to the Gobecho catchment. Ererti is a station geographically near to Gobecho catchment by using GIS 10.7 application. The Gobecho peak probable discharge of 3.503m3/s is computed using log normal distribution after L-moment analysis. Based on this peak discharge, vertical drop weir and components of headwork structure designed and provided relevant dimensions. The proposed vertical drop weir has a height of 0.703m, crest length 10m and the design flow for a hydropower scheme is 0.132m3/s estimated by FDC. The water passes through trapezoidal power canal of a 0.35m width and a 0.43 height to a forebay tank. A forebay of size 9 × 1.3 × 1.7 is provided at the end of the power canal. Moreover, the water leads from forebay to a 0.24m diameter of penstock running one unit turbine and capacity of 25kw. The selected type of turbine for proposed plant is cross flow turbine. Finally, the quantity of calculated estimate cost is 50,000 USD and the B/C ratio of 1.48 provided for this micro hydropower project.

Modelling and parameter extraction of the solar cell is difficult for the researcher due to the nonlinear characteristics of voltage and current. Optimization is the best technique through which we can obtain the optimum parameters from a nonlinear model. Recently, there are a number of optimization techniques that are applied for the estimation of the optimum parameter from solar, but still it is not achieved to date. In the present research, we proposed Improved Grey Wolf Optimization (HPSOGWO) for identifying the optimum parameter of a solar cell. Relative error, convergence speed, accuracy, and stability of the final solution are the statistical result which is compared with the particle swarm optimization (PSO) and Grey wolf optimization (GWO) for a single diode model and double diode model of a solar cell. A comparative study reveals that the improved version of the GWO tool provides a more accurate model for the estimation of the optimum parameter of a solar cell with less number of iteration. Hence, we recommended that HPSOGWO is the best optimization tool for providing the perfect promising performance.
