Abstract: The solid oxide fuel cell (SOFC) is widely acknowledged for clean distributed power generation use, but critical process problems frequently occur when the stand-alone fuel cell is directly linked with the electricity grid. To guarantee the optimal operation of the SOFC in a power system, it is essential, that its generation ramp rate and load following is fast enough to sustain power quality. In order to address these problems, a suitable and highly efficient control system will be required to control and track power load demands for complex SOFC power systems under grid connection. Therefore, novel nonlinear hybrid adaptive Fuzzy Neural Network (AFNN) is developed for control of grid connected SOFC. During peak power demand schedules from electric utility grid and large load perturbations, maintaining optimal power quality and load-following is a big challenge. Both the rapid power load following and safe SOFC operation requirement is taken into account in the design of the closed-loop control system. Simulation results showed that the proposed hybrid AFNN enhance the optimal power quality and load-following than conventional PI controller.

Abstract: Since 2007, Honda China Eco Mileage Challenge was held for 7 years, so far, nearly hundred teams participated in the competition. Although the national ranking of our school’s fuel econopower cars is ideal, but the competition results between our school and high level universities is remote. For raising the grade of the econopower car, this paper analyzed the articles about econopower car that published in recent years, discusses the main research direction of econopower car and main achievements, analyse it from the main research direction and research method, offer the technology of econopower car at current in domestic, summarizes the research trend of econopower car, make guidance for the future design of econopower car, also.

Abstract: Due to fast industrialization the consumption as well as the cost of fossil fuels like petrol, diesel etc in the world is rising enormously leading to the generation of greenhouse gases like carbon monoxide, carbon dioxide etc besides decreasing the availability of the above fuels. The emission of these greenhouse gases rises the globe’s temperature leading the earth to face many dangerous complications. In order to save the earth from effect of rise of temperature and also to have an eco-friendly alternate energy fuel especially for the transport sector, attention is being focused on the generation of hydrogen gas which meets the above situations. During the combustion of hydrogen gas it emits only the beneficial water vapour to the atmosphere. In this research paper investigation has been carried out through CuCl-HCl electrolysis with 1M CuCl anolyte and 6M HCl catholyte for the generation of hydrogen gas at 70oC at normal atmospheric pressure employing a double compartment electrolytic cell having a nafion cation exchange membrane-324. Anode was graphite and cathode was 0.30 mg cm-2 platinum coated graphite. At a current density of 250 A m-2 the current efficiency for the oxidation of CuCl to CuCl2 and the formation of hydrogen gas was nearly 100% and the rate of hydrogen liberation was found to be 2 l h-1. Voltage efficiency and energy consumption values are calculated and are found to be more encouraging since they are more economical with less energy operation. The formed CuCl2 was reduced back to CuCl anolyte by chemical reduction with copper powder in 6M HCl at 70oC and the regenerated CuCl anolyte was again used in the CuCl-HCl electrolysis.

Abstract: This paper presents an implementation of MEPE test system in Power System Analysis Toolbox (PSAT)—free and open source software. This paper mainly focuses on the application of newly developed hydro turbine and governor model with detailed dynamic power system models on Myanmar national grid because the power system network is largely supplied by hydro power. This paper also demonstrates the rotor angle stability analysis of test system including classical small signal stability and transient stability criteria. Transient stability assessments of national grid test system are carried out through nonlinear time domain simulation by applying both large and small disturbances. Moreover, a statistical t-test is performed to ensure the effective of proposed model to deal with dynamic problem of the power system.

Abstract: Lack of cultural knowledge, poor livelihood and inappropriate value orientation of electric power universal service recipient groups basically influence their electricity consumption habit in china. In order to assess the effect of power universal service distribution and measure the welfare of recipient groups, this paper researches individual electricity consumption mentality and behavior through behavioral economics theory, establishes a subjective welfare function tracing recipient individual based on cumulative prospect theory , constructs the recipient groups’ subjective welfare function following the traditional social welfare function and researches the influence of the changes of psychological reference points. Through example analysis combined with function feasibility, this paper proves the subjective well-being effect of recipient groups declines when the psychological reference point increases.

Abstract: Switched reluctance motors (SRM) have a wide range of applications in industries due to the special properties of this motor. However, because of its dynamical nonlinearities, so the problems control of SRM is complex. This paper proposed an adaptive intelligent controller for SRM with the aim to improve the ripple of torque. First, we use a fuzzy logic controller to control switch-off angle, and then proposes a new controller by means of Adaptive Neural Fuzzy Inference (ANFIS). Simulation results are given to show the efficacy of the proposed method.
