Noise Control Solutions for Diesel Generator Sets

A persistent challenge for Oman's energy infrastructure was the deafening rumble of diesel generators. The Silent Generator Project addressed this challenge, developing advanced generators that deliver power quietly and efficiently. Diesel generators have historically been notorious for being noisy and vibrational, making them unsuitable for sensitive environments. To dramatically reduce noise levels, the project utilized innovative materials and design modifications to ensure reliable and quiet electricity for various applications. In all directions, the project advanced the knowledge of noise reduction through rigorous testing and meticulous integration of insulators and mufflers. As a result, quieter, more sustainable energy production is on the way, marking a major advance in silent generator technology. Furthermore, the Silent Generator Project lays the foundation for more efficient and environmentally friendly diesel generator technologies in the future. As a result of this research, a new standard for quieter, greener energy generation is established, demonstrating the critical role noise reduction plays in energy generation. Additionally, this work also suggests future diesel generator technologies that are more efficient and environmentally friendly. As a result of this research, a new standard for quieter, greener energy generation is set, demonstrating the critical role noise reduction plays in energy generation.

Economic Assessment of Standby Diesel Generator for Peak Reduction in Commercial and Industrial Buildings:A Case Study in Malaysia

This paper outlines the barriers and potential benefits of using standby diesel generators in mitigating the peak demands for commercial and industrial customers. The feasibility of utilizing the standby diesel generators to reduce the electricity bills for customers is carried out by using the hybrid optimization model for electric renewable(HOMER)software. The size of the standby diesel generator and its operational duration are determined based on the lowest cost of electricity obtained from the evaluations. The economic assessments demonstrate that there is potential to reduce the electricity bills for commercial and industrial customers under the existing fuel price and tariffs. The commercial customers under the tariff C2 have the highest potential to save their electricity bills with the use of standby diesel generators for peak reduction. This study demonstrates the potential of the standby diesel generators in peak reduction.

Air pollutants and greenhouse gases emission inventory for power plants in the Antarctic

Emissions of air pollutants and greenhouse gases into the atmosphere in Antarctica from power plants with diesel generators(the main sources of energy at Antarctic research stations and the main stationary sources of anthropogenic emissions in the Antarctic)were assessed.A bottom-up approach was used to compile an emission inventory for the Antarctic.This involved estimating emissions at various spatial levels by sequentially aggregating estimate emissions from point emission sources.This is the first time this approach has been proposed and used.Emissions of CO2,NOx,particulate matter(PM10),and CO in the modern period were estimated at the research station,geographic region,natural domain,biogeographic region,continent section,and whole continent scales.Yearly emissions are presented here,but the approach allows emissions at different averaging periods to be estimated.This means mean or maximum yearly,monthly,daily,or hourly emissions can be estimated.The estimates could be used to model pollutant transmission and dispersion,assess the impacts of pollutants,and develop emission forecasts for various scenarios.

Optimal Energy Management and Techno-economic Analysis in Microgrid with Hybrid Renewable Energy Sources

Microgrids with hybrid renewable energy sources are increasing and it is a promising solution to electrify remote areas where distribution network expansion is not feasible or not economical.Standalone microgrids with environment-friendly hybrid energy sources is a cost-effective solution that ensures system reliability and energy security.This paper determines the optimal capacity,energy dispatching and techno-economic benefits of standalone microgrid in remote area in Tamilnadu,India.Microgrids with hybrid energy sources comprising photovoltaic(PV),wind turbine(WT),battery energy storage system(BESS)and diesel generator(DG)are considered in this paper.Various case studies are implemented with hybrid energy sources and for each case study a comparative analysis of techno-economic benefits is demonstrated.Eight different configurations of hybrid energy sources are modeled with renewable fractions of 50%,60%,65%,and 100%,respectively.The optimization analysis is carried out using Hybrid Optimization Model for Electric Renewable(HOMER)software.Impact of demand response is also demonstrated on energy dispatching and technoeconomic benefits.Simulation results are obtained for the optimal capacity of PV,WT,DG,converter,and BESS,charging/discharging pattern,state of charge(SOC),net present cost(NPC),cost of energy(COE),initial cost,operation cost,fuel cost,greenhouse gas emission penalty and payback period considering seasonal load variation.It is observed that PV+BESS is the most economical configuration.COE in standalone microgrid is higher than the conventional grid price.The results show that CO2 emissions in hybrid PV+WT+DG+BESS are reduced by about 68%compared with the traditional isolated distribution system with DG.
