Diesel generators are being used as a source of electricity in different parts of the world. Because of the significant expense in diesels cost and the requirement for a greener domain, such electric generating systems appear not to be efficient and environmentally friendly and should be tended to. This paper explores the attainability of utilizing a sustainable power source based on a cross-breed electric system in the cement factory in Salalah, Oman. The HOMER software that breaks down the system setup was utilized to examine the application and functional limitations of each hybridized plan. The result showed that a renewable-energy (RE)-based system has a lower cost of energy (COE) and net present cost (NPC) compared to diesel generator-based hybrid electric and standalone systems. Although the two pure renewable hybrid energy systems considered in this study displayed evidence of no emissions, lower NPC and COE values are observed in the photovoltaic/battery (PV/B) hybrid energy system compared with photovoltaic/wind turbine/battery (PV/WT/B). The PV/WT/B and PV/B systems have higher electricity production and low NPC and COE values. Moreover, the PV/B has the highest return on investment (ROI) and internal rate of return (IRR), making the system the most economically viable and adjudged to be a better candidate for rural community electrification demands.

The independent small-scale networks including sustainable power sources have been used in remote regions around the globe. Nonetheless, the irregularity of vitality sources may cause an enormous variance of the miniaturized scale framework recurrence. Because of consistently expanding vitality utilization, rising open familiarity with ecological assurance, and relentless advancement in power deregulation, distributed generation (DG) frameworks have pulled in expanded intrigue. Wind and photovoltaic (PV) power age are two of the most encouraging sustainable power source advancements. Fuel cell (FC) frameworks likewise show incredible potential in DG utilizations of things to come because of their quick innovation improvement and numerous benefits they have, for example, high effectiveness, zero or low outflow (of contamination gases), and adaptable measured structure. In proposition investigated work Integration of Distributed Generating Systems for Non-straight Loads will be proposed. A run-of-the-mill wind-PV-diesel reconciliation which comprises of diesel generator, PV framework, wind turbine generator (WTG), BESS, and burden, is utilized for the proposed models and controllers. We reenact and Integration Distributed Generating Systems for Non-straight Loads on the MATLAB/SIMULINK and portions of coordinated vitality frameworks are analyzed. The coordinated PV framework is normally controlled to work in the maximum power point tracking (MPPT) mode. The battery vitality stockpiling framework is worked inconsistent force charging or releasing mode. So as to give an incorporated vitality framework associated with lattice relying upon singular vitality necessities, the Integrated Energy Systems can be extra to a current vitality source to lessen petroleum product utilization or an independent for complete non-renewable energy source uprooting Through the broad joining of vitality foundations it is conceivable to upgrade the supportability, adaptability, steadiness, and productivity of the general vitality framework. The reproduction of incorporated vitality frameworks is done in MATLAB/SIMULINK. And all framework results will be done by Matlab reproduction is proposed for disconnected smaller scale matrices with sustainable sources. In the exhibited method, the pitch point controller is intended for wind turbine generator (WTG) framework to smooth breeze power yield. The proposed procedure is tried in a regular secluded incorporated small-scale network with both PV and wind turbine generators.

The aims of this paper are to develop hybrid energy systems considering biomass energy sources as well as a framework and optimal configuration of hybrid systems of energy for a southern sub-urban area of Bhola district in Bangladesh, named Kukri Mukri island, and analyse the feasibility of the techno-economic prospects of these systems. In this work, electrification for the rural area is analysed for different configurations of the hybrid systems. The estimation of available resources with optimal sizing and analysis of techno-economic aspects is done through HOMER Pro software to satisfy the demand of peak load. Different configurations of hybrid energy systems, including PV/diesel, PV/wind, PV/diesel/wind, PV/wind/diesel/biomass, and wind/diesel, are analysed and compared through optimization of different energy sources in HOMER. The size of the system and components are optimized and designed depending on the net present cost (NPC) and the levelized cost of energy (LCOE). Due to the lower availability and rising cost of wind energy, the outcome of this work shows a solar-based photovoltaic (PV) as the main energy source, battery as the storage media, and diesel generator as an energy source for backup. The results indicate that LCOE is much lower for PV/wind/diesel/biomass (0.142 USD/kWh) than PV/diesel (0.199 USD/kWh), PV/wind (0.239 USD/kWh), PV/diesel/wind (0.167 USD/kWh), PV/diesel (0.343 USD/kWh), and wind/diesel (0.175 USD/kWh). Additionally, it is demonstrated from the research that the genetic algorithm (GA) process gives sustainable and cost-effective outcomes compared to HOMER.
