DC microgrid systems allow commercial buildings to use locally generated energy and achieve an optimal economy efficiently. Economical eco-friendly can be achieved by employing renewable sources. However, additional controllable sources, such as fuel cells, are required because of their reduced efficiency fluctuated nature. This storage supply transient power enhance stability. The functioning ...

arguably, the natural gas transmission pipeline infrastructure in iran represents one of the largest andmost complex mechanical systems in the world. the optimization of large gas trunk lines known asigat results in reduced fuel consumption or higher capability and improves pipeline operation. in thecurrent study, a single-objective optimization was conducted for khormoj compressor station on t...

This paper presents a multi-objective Particle Swarm Optimization (PSO) algorithm for worker assignment and mixed-model assembly line balancing problem when task times depend on the worker’s skill level. The objectives of this model are minimization of the number of stations (equivalent to the maximization of the weighted line efficiency), minimization of the weighted smoothness index and minim...

Arguably, the natural gas transmission pipeline infrastructure in Iran represents one of the largest and most complex mechanical systems in the world. The optimization of large gas trunk lines known as IGAT results in reduced fuel consumption or higher capability and improves pipeline operation.

In order to further improve the energy utilization of range extender electric vehicle (REEV), management strategy REEV under different heat demands and operating temperatures is studied. Firstly, for reducing extra fuel consumption caused by engine temperature, influence lubricating oil temperature on equivalence factor analyzed, a novel method proposed, which can determine three parameters, in...

Well-designed energy management strategies are essential for the good operation of Hybrid Electric Vehicles (HEVs) in terms fuel economy and pollutant emissions reduction, regardless specific powertrain architecture. The goal this paper is to propose two innovative supervisory control HEVs derived from different optimization algorithms assess HEVs’ consumption reduction (compared conventional v...

Fuel consumption reduction is one of the main challenges in the automotive industry due to its economical and environmental impacts as well as legal regulations. While fuel consumption reduction is important for all vehicles, it has larger benefits for commercial ones due to their long operational times and much higher fuel consumption. Optimal control of multiple energy buffers within the vehi...

This paper deals with hybrid electric fuel cell-powered drones energy management while targeting hydrogen saving and power supply system efficiency improvement. In this context, a commercially available quadcopter powered by the Intelligent Energy 650 W module is adopted as case study. Its based on cell battery, conventionally managed using basic rule-based strategy. To improve management, freq...

The problem of adapting the equivalence factor of the Equivalent Consumption Minimization Strategy (ECMS) to achieve a real time implementable sub-optimal solution of the problem of energy management in hybrid electric vehicle (HEV) has been the object of extensive research over the last decade. Contributions in the open literature range from methods based on prediction of driving cycle to driv...
