Large capacity of wind generation is expected to be installed across Great Britain by 2020. Wind generation is variable, therefore fast ramping generation plants will be required to balance electricity demand. Gas-fired generation plants will most likely be used to compensate for wind generation variability because of their ramping capability and large installed generation capacity. This will cause...
This Paper presents an Oppositional Biogeography-Based Optimization algorithm to solve complex Economic Emission Load Dispatch (EELD) problems of thermal power systems. Emission of NOx and SOx are considered for case studies. The proposed method is a modification over Biogeography-Based Optimization technique, designed to accelerate its convergence rate and to improve the quality of solution. This...
This paper provides an analysis of the BADA aircraft performance model capabilities and addresses the BADA model ability to provide accurate modeling of aircraft performances over the complete flight envelope for a number of aircraft types and different ways in which an aircraft can be operated during the flight. The focus of the paper is the support of complex aircraft operations by BADA. A short...
The objective of the research done in this paper was to determine cost of the power and heat system with pressurized fluidized bed gasifier using exergoexonomic appraisal techniques. Exergetic efficiency maximization was approached with use of multi-objective evolutionary optimization methods which were designed such that the costs were minimized in line with the exergoeconomic plans. The results...
Combining solid oxide fuel cell and gas turbine (SOFC/GT) system is a promising concept for future clean and efficient power generation. An SOFC/GT system exploits the complementary features of the two power plants, where the GT recuperates the energy in the SOFC exhaust stream and thereby boosting the overall system efficiency. Through model based transient analysis, however, it is shown that the...
This paper demonstrates that optimal selection of renewable power generators and energy storage devices in a grid-connected micro-grid, in conjunction with an optimal dispatch strategy, can significantly reduce the micro-grid lifetime cost and emission. The paper presents a mathematical model and optimization algorithm to identify the optimal micro-grid configuration (in terms of the installed capacities...
A new class of meta-heuristics called SOMA (Self-Organizing Migrating Algorithm) was proposed in recent literature. SOMA works on a population of potential solutions called specimen and it is based on the self-organizing behavior of groups of individuals in a ??social environment??. This paper proposes a modified SOMA approach to solving the economic load dispatch problem of thermal generators with...
The optimized theory is used in the electronic control of the power train in order to improve the performance of the car. Except that, the author explains the optimized theory and the method of using it in writing the computer program. And moreover, the author discusses the problems occurring in the object and gives the methods to solve them. The result of the object is expressed by figures and gives...
A four-stroke direct injection diesel engine is taken as the study object, and a cylinder-jacket-coolant-piston coupling model is built up. With the research method of fluid- solid-heat coupling, the computational regions of both fluid and solid are coupled, which are separated in traditional temperature-field computation, and the puzzle of iterating difficultly due to the differences of temperature...
The complex mathematical model of thermal treatment of ingots was constructed for the technical system ldquosteel-rollingrdquo, its numerical solutions were obtained, and the multiparametrical analysis was carried out. New regularities of combined processes were found out on the basis of calculations performed. The multicriterion optimization of thermal preparation of ingots of rimmed and balanced...
