This paper aims at improving power generation efficiency of marine diesel engine waste heat recovery systems. It presents a novel technique of integrating the heat rejected in the scavenge air cooling process and the exhaust gas in operating a single and dual pressure steam power generation cycles. Moreover, a thermodynamic analysis of proposed systems was performed to identify the optimum operating...
This paper presents a new coordination framework to optimize the joint operation of pumped-storage unit, irrigation system and intermittent wind power generation in an agricultural microgrid. The microgrid is an agricultural complex connected to the medium voltage network. This complex contains a farm needing water to be irrigated every day. The irrigation system has two large scale reservoirs located...
Energy storage technologies will play a crucial role in increasing both the efficiency as well as the availability of renewable energy. Compressed Air Energy Storage (CAES) enables the efficient and cost effective storage of large amounts of energy–usually above 100 MW.However, this technology is limited by the inherent risks of underground exploration. In order to reduce this handicap, we propose...
Energy has been the major input for the national economies. While fossil-based energy resources are diminishing, researchers are focusing on alternative fuels and various technology options for conversion, distribution, and end user's operating environment processes. As the search for the alternative pathways for the “sustainable economy” idea continues, management factor is getting considerably important...
The Swedish pulp and paper industry (PPI) must increase energy efficiency to remain competitive on the global market, which has experienced entries from countries with cheaper energy and raw material supplies. Interactions among variables for energy use, production, energy management, electricity price and firm characteristics (FC), in different types of mills, i.e., pulp, paper and integrated mills,...
The real penetration of renewable energy sources under random variability and unpredictability of weather conditions requires an optimal sizing of hybrid renewable power generation systems. This paper presents a techno-economic optimization model, to perform the optimal sizing of a stand-alone hybrid photovoltaic/wind/hydrogen/battery system. Optimum sizing has been applied to a system consisting...
The current tendency in energy domain is to reduce fuel consumption in favor of sustainable energy approaches. In this frame, the present work suggests an efficient way of heat recovery from boilers using concentric tube. The motivation behind the suggested concept is that it could be considered the cheapest, easiest to construct and simplest to use among all the existing heat recovery systems. In...
Although future widespread use of plug-in electric vehicles (PEVs) will considerably reduce the greenhouse gas emissions, their charging demand will pose significant challenges to the grid. Aggregated charge scheduling of PEVs in parking lots (PLs) can mitigate the challenges, if the size and place of the PLs for PEVs are optimally determined. This paper proposes an optimization-based problem to not...
Coupling water desalination processes with Renewable Energy Sources (RESs) can be a sustainable and ecological approach to the global water/energy supply crisis. In this regard, small-scale standalone battery-less Brackish Water Reverse Osmosis (BWRO) desalination system powered by a hybrid PV/Wind RES is expected to meet freshwater demand of a small isolated community. One particularity of the proposed...
In this study, dynamic particle swarm optimization was used to develop optimal strategies for two-variable energy management and gear-shifting in hybrid electric vehicles. To perform simulations, six mathematical subsystems, including a spark ignition engine, lithium battery module, traction motor, automatic manual transmission, longitudinal vehicle dynamics, and driver model were constructed. The...
Multi energy system is considered an effective pattern to improve the energy efficiency and reduce energy supply cost by integrating multi energy carriers. Face abundance energy convertor and storage devices with various characteristics, how to select the types and capacities of devices, how to connect and manage the selected devices are core challenging problems to design the optimal structures of...
