“…The grades are D, E, and F with gross calorific values (GCV) ranging from 4200 to 4940, 3360 to 4200, and 2400 to 3360 kcal/kg (Bureau of Energy Efficiency 2015 ), respectively. The GCV of coal considered in this investigation for calculations is 4000 kcal/kg (Acharya 2022 ). In a coal-based thermal power plant, the boiler efficiency varies between 70 and 80% and vapour cycle efficiency ranges from 30 to 40% (Zhengzhou Boiler Group Co. Ltd. 2017 ).…”

Most of the electricity at present is generated from hydrocarbons like coal and gas. Their combustion is polluting the environment and raising the global temperature. Hence, there is an enhancement in catastrophes like floods, tornados, and droughts. Consequently, some part of the Earth is sinking, whereas there is a dearth of drinking water in some other part. A tribo-generator-integrated rainwater harvesting system for electricity and drinking purposes is proposed in the present paper to address these issues. A setup of the generating section of the scheme is developed and experimented in the laboratory. The obtained results show that the triboelectricity from rainwater depends on the rate of droplets falling per unit time, the height from which they are descending, and the coverage area of hydrophobic material. When released from 96 cm, the low- and high-intense rain generates 67.9 and 189 mV, respectively. Conversely, the electricity from the nano-hydro generator is proportional to the flow rate of water. 71.8 mV is observed at an average flow rate of 49.05 ml/s.

Due to the increased demand for electrical energy, many countries were prompted nowadays to search for new sources. One important source is the photovoltaic energy. However, despite the great benefits of this source, some defects where observed when linking to distribution networks (negative impact on the protection system). Hence, an approach of improving the protection system in distribution networks integrated with photovoltaic cells is presented in this paper. The protection system improvement is proposed by changing the impedance to resistance ratio (X/R) values of the networks cables, which leads to increasing the overcurrent relays' response speed when a fault occurs. A comparative analysis with different cable reactance values was conducted. The electrical transient analyzer program (ETAP) software was used to investigate and validate the effects on the relay’s response times. Amriya Fallujah power station, located in Iraq, was investigated as a case study. Simulation results show that it is possible to increase the response speed of the overcurrent relay by reducing X/R of the network cables. For more validation, the distance relay was used to compare the best improvement results of changing the X/R ratio with the results of changing the type of relay, which also shows the strength of the proposed method.
