islanding detection methods for microgrids

امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...

Improvements in time domain FWI and its applications

In this abstract, we describe how to improve time domain full waveform inversion using source wavelet convolution, windowed back propagation and source side illumination. Instead of estimating the source wavelet from field data, a user defined source wavelet can be convolved to field data. This convolution makes waveform matching between modeled and field data easier. Increasing time window app...

Checkpointing strategy for multiple real-time tasks

We analyze checkpointing strategy for multiple realtime tasks with deadlines. Real-time tasks usually have deadlines associated with them. For multiple real-time tasks, checkpointing strategy considering deadlines of all tasks is very difficult to derive. We analyze the problem of checkpoint placement for such multiple tasks. In our strategy, the interval between checkpoints are determined for ...
