As part of this project over the past two years, a general methodology (ILGO) for the decomposed synthesis/design optimization of highly coupled, highly dynamic energy system has been developed applied to an aircraft propulsion sub-system (PS) coupled to an environmental control sub-system (ECS) and is being applied to a combination of coupled aircraft sub-system, namely, a PS, and ECS, a TMS (thermal management sub-system) and a SS (structural sub-system). It is our intention at the completion of this project to have solved this problem in its entirety, resulting in a Ph.D. dissertation already completed and submitted as our annual report in year one of this project and an M.S. thesis. The latter of these will serve as our final report for the final phase of this project to be complete next year. In the meantime, however, for the purpose of this project, some preliminary results are presented showing the influence of the various coupling function (an integral part of ILGO) on the unit-level and system-level, unit-based synthesis/design optimization of the PS, ECS, and TMS (i.e. fuel loop sub-system (FLS) and vapor refrigeration /PAO loops sub-system (VC/PAOS). Furthermore, for the time being, no decision variables are used for the SS, which is solved as an integral part of the PS.

The paper presented a hybrid micro-grid renewable energy of different energy sources to generate uninterrupted electricity for the Agu-Amede village using PV, diesel, biogas, and battery. The system optimization was performed to determine techno-economic analysis and energy generated using HOMER software. The energy generated by the hybrid system was able to meet the demand load of the village at all levels of biomass production with surplus electricity in each case when the production of the biogas system varied between 0.5 tons to 3 tons. At biomass production of 3 tons, the total energy generated demand is 480693 kWh with a surplus of 121762 kWh. Again, the hybrid PV and biogas system generate total energy of 98714 kWh (20.50%) and 381979 kWh (79.50%), respectively. The net present cost (NPC) and cost of energy (COE) of the base case architecture (diesel) measured are $1230000 and $0.267/kWh, respectively. Therefore, between 2.5 tons and 3.0 tons of biomass penetration, the energy production of biogas increased, and the diesel system was removed from the hybrid system setup. This is because the availability of biogas is almost sufficient to meet the load demand at a lower cost and solar PV architecture was added to the hybrid system to balance energy production.

NTROL, BOMB RELEASE POINT, FORTRAN, FORTRAN 4 PROGRAMMING LANGUAGE, CONTROL THEORY. The concern in the work reported is the development of a dynamic precision weapon delivery system model for analyzing the effects of system parameters and disturbances on delivery performance. In addition, a methodology of precision weapon delivery flight control design is developed, without considering the pilot as a control element. The aircraft model accommodates a wide variety of airframe nonlinear dynamics, control points and methods and measurement systems. The bomb model is general enough for a variety of dive-bomb angles, release altitudes and release speeds. The circular error probable (CEP) at impact is chosen as a measure of weapon delivery performance, and a technique is developed for relating the effects of flight control parameters, airframe dynamics, measurement errors and gust disturbances to this measure by using the system model. Demonstration analysis is performed to show how to identify critical system parameters with regard to the delivery of an iron bomb and to illustrate how the method of analysis can be used. Digital computer subprograms (in FORTRAN 4 language) were developed and documented implementing the mathematical models.

The Hydrogen-Oxygen Regenerative Fuel Cell System was identified as a key component for energy storage in support of future lunar missions. Since the H2-O2 regenerative electrochemical conversion technology has not yet been tested in space applications, it is necessary to implement predictive techniques to develop initial feasible system designs. The ASPEN simulation software furnishes a constructive medium for analyzing and for optimizing such systems. A rudimentary regenerative fuel cell system design was examined using the ASPEN simulator and this modular approach allows for easy addition of supplementary ancillary components and easy integration with life support systems. The modules included in the preliminary analyses may serve as the fundamental structure for more complicated energy storage systems.

The Modeling and Optimization of Building the Multi-dam System on Zambezi River 作者： Xie,Pengcheng 1 作者单位： 1.

Firstly, we make a threshold analysis of the three options about their costs which include peoples moving, old dams removing, new dams building, later repairing, ecological destruction and their incomes which include generation energy, avoiding of flood disasters loss, providing employment, tourism resources and ecological protection. Then we get the specific relationship between benefits and years with some collected data. Both of the results show that the third option is the best choice from the economic view. And the result is completely as same as the conclusion we get after studying deeply on Option 3. Secondly, we regard water management capabilities as the safety coefficient of dams. We select 30 seed points along the riverbank for preparing the establishment of dams. With flow-between-riverway model, Manning equations, large Cauchy distribute function we get the scores of the seed points. We give an advice that the number of dams should be more and the positions of dams should be well-distributed. Then, we build an assessment model by analytic hierarchy process. We select three factors among all the factors, safety, economy and population. After testing the consistency, we get the weights of each factor: 0.6442, 0.2705, 0.0852. Then we value the factors and get an optimal scheme during the assessment with 0-1 integer programming: the number of dams is 17 and the longitude and latitude of them are shown in Table 17. The sensitivity of the result is tested as well. We also provide some strategies for the managers of ZRA to use. We suggest that they should use the dams normally in general. With the Dam-break model, we find 13 points among 17 points which are shown in Table 20. The dams at the 13 points need to be closed when there is a flood and it is just the opposite when the drought happens. For the extreme water flow, we assume an ideal water flow at first. The extreme water flow has to be adjusted to satisfy the ideal one. As for the restrictions in extreme conditions, the biggest impact happens at the 8th point among the 17 points. If the duration of maximum flow is t0, the drainage time t to make the water flow return to the normal level equals to 4.95t0. multi-dam system assessment model multi-objective optimization model 来自： 谢鹏程 分类： 数学 >> 数学（综合） 水利工程 >> 水利工程基础学科 投稿状态： 未投稿 引用： ChinaXiv:202304.01057 (或此版本 ChinaXiv:202304.01057V1 ) doi:10.12074/202304.01057 CSTR:32003.36.ChinaXiv.202304.01057.V1 推荐引用方式： Xie,Pengcheng.(2023).The Modeling and Optimization of Building the Multi-dam System on Zambezi River.中国科学院科技论文预发布平台.[ChinaXiv:202304.01057] 版本历史 [V1] 2023-04-28 01:09:38 ChinaXiv:202304.01057V1 下载全文

As a promising alternative to fossil fuels, cellulosic biofuel has obtained considerable interest due to its potential for mitigating global climate change and enhancing energy security. However, the widespread adoption of cellulosic biofuel is taking place in a slower pace than expected. One major challenge is that the cellulosic biofuel production is still highly energy-intensive. In fact, the energy contained in cellulosic biofuel is less than the energy required for its production. To address this issue, in this paper, an analytical system-level energy model is proposed to characterize the fundamental relationships between total energy consumption and biofuel production parameters in cellulosic biofuel production systems. Furthermore, an optimization strategy based on Particle Swarm Optimization (PSO) is adopted to minimize the energy consumption of cellulosic biofuel production while maintaining the desired biofuel yield. A baseline case is implemented for analyzing energy consumption, and the results show that pretreatment consumes most energy among all processes and the water/biomass ratio is the most significant energy driver. In addition, the optimal solution results in a 21.09% reduction in the total energy consumption compared to the baseline case.
