This paper has analyzed the impact of large induction motors on the dynamic performance of distribution networks in the presence of a wind farm. The study is restricted to wind farms with small installed capacity compared to the local industrial plants. The results show that the technology of the wind …

The following conclusions can be drawn from the present study: The increase in alcohol content in diesel or biodiesel fuels always led to an increase in both IDCF and IDM. Such an increase was sharper at high alcohol contents. This implies that weight or volume averaging of autoignition parameters (such …

This book explores the electric railway systems that play a crucial role in the mitigation of congestion and pollution caused by road traffic. It is divided into two parts: the first covering fixed power supply systems. and the second concerning the systems for railway rolling stock. In particular. after a …

Novel underground well pattern systems. replacing fracturing reservoir with horizontal wells. were proposed for geothermal energy exploitation in this paper. The most important feature of the well pattern systems was the wholly closed circulation inside the wellbores. Compared to the fractured reservoir system where the fluid flowed in the porous …

The energy problems experienced in Sub-Saharan Africa today can only be solved by the decentralization of energy generation to the smallest subset possible. To achieve that. renewable energy must be considered and utilized. This supports the generation of clean energy and would contribute enormously to the “unofficial economy“ that is …

In our works. we set up a model of solar cell VLC system which was simulated in Matlab Simulink. We had verified the correction of the model and gave reasonable design to optimize the system. The energy gathering and signals detecting system was demonstrated. The data rate of it is …

The novel and simple yet efficient system of HTHPSS (High Temperature Heat and Power Storage System) suitable for the locations with high heating demand as well as electricity demand was previously proposed and investigated in terms of economic justification by the authors [9]. In the present work. a detailed dynamic …

Life cycle assessment of an innovative multi-use offshore platform design. which unites wind and wave energy production in one platform. was executed in this study. By all means. the main contributor to all of the impact categories was manufacturing processes of MUP design. Due to having a design which requires …

The mathematical model of the three-phase grid-side PWM converter in d-q synchronous reference frames is thoroughly investigated. Comparing with the tradition control way of PWM converter. this method doesn’t demand high accuracy of mathematic model. and has little sensitivity of parameter change and the external perturbation. which can control a …

This work has been devoted to modeling. simulation and analysis of a wind turbine operating at variable speed. A stable operation of the wind energy system is obtained with the application of nonlinear Backstepping Adaptive control. The overall operation of the wind turbine and its control system were illustrated by …
