In this work. a jacket structure was designed based on Korean Southwest Sea conditions to support a 5 MW OWT at a water depth of 33 m. In addition. the effects of different modeling parameters. including joint can. overlap. flooding the member. marine growth and TP mass. were investigated using …

Extracting electric energy from wind using a technology without moving parts has been a temptation for decades. The challenges have stemmed from the fact that a solution requires a multiphysic approach and mastering various fields of technology. such as effective production of charged particles. a twophase flow and proper handling …

In this work. we address the problem of energy-aware routing with distributed energy replenishment. We formulate the problem as an integrated admission control and routing framework by appealing to ideas from PVC SVC routing in the ATM literature. The energy model in this framework allows vastly different energy sources in …

Silicon heterojunction (SHJ) solar cell called HIT (heterojunction with intrinsic thin-layer). developed by SANYO Ltd. in 1994 (Sawada et al.. 1994). is produced by plasma enhanced chemical vapor deposition of thin hydrogenated amorphous silicon (a-Si:H) layers on both sides of a high quality crystalline silicon (c-Si) wafer. Such novel solar …

This paper presents a comparative investigation of solar photovoltaic (PV) effect on system stability at different penetration levels. Three different scenarios with their relevant dynamic models are considered. namely. distributed units. and centralized farms with and without voltage regulation capabilities. Based on these models. the impact is examined through eigenvalue. …

As wind power generation undergoes rapid growth. new technical challenges emerge: dynamic stability and power quality. The influence of wind speed disturbances and a pitch control malfunction on the quality of the energy injected into the electric grid is studied for variable-speed wind turbines with different power-electronic converter topologies. Additionally. …

In recent years. wind energy becomes one of the most important sources for electricity production. For instance it is predicted that the installed wind capacity in China will be about 40 GW till 2020. The permanent magnet synchronous generators (PMSG) which contains of a permanent magnet that causes DC excitation …
