درود بر همگی دوستان قدیمی

امروز توی خیابان شریعتی پیاده و قدم زنان در حال حرکت بودم که نگاهم به چهره ای آشنا خورد، که خیلی وقت بود او را ندیده بودم. مهرداد خضری نیا، با همان قیافه ی خندان و شاد، فرصت بسیار خوبی به من داد تا دوباره خاطرات گذشته را مرور کنم. و نهایتا به این فکر افتادم که چرا امسال دید و بازدید سالیه ۱۳۹۲ برگزار نشد...

متاسفانه تابستان امسال تمام شد و دید و بازدید سالیانه که طبق روال سالهای گذشته انجام می شد و عده ای از دوستان هنوز بر آن پایبند بودند و شرکت می کردندی، البته تعدادی دیگر هر سال تغییر می کردند و جای به دیگری می سپاردند اما تعداد قابل قبولی از دوستان هر ساله حضور به عمل می رساندند، تا به الان برگزار نشده است.

و اما امسال بنده از آقای مهندس حسینی خواهش کردم در اولین سفری که به کرمان می آیند زحمت اطلاع رسانی و هماهنگی ها و در کل مدیریت قضیه را بعهده بگیرند که ایشان پذیرفتند اما متاسفانه نمی دانم که چگونه ماجرا رقم خورد که تا به الان هیچ اتفاقی قابل توجه ای صورت نگرفته است.

به هر شکل به امید خدا تا قبل از پایان امسال بر آن هستیم که حتما این جلسه را برگزار کنیم.

از کلیه دوستان که به وبلاگ سر می زنند، از تعداد قابل توجه ای اطلاع دارم که فراموش نکرده اند، عاجزانه خواهشمندم که نظرات خود راجب این جلسه ارسال کنید.

همه در قدرت لینوکس و قابلیت های آن واقفیم . اما یکی از مشکلاتی که ما به سمت لینوکس نمیریم کار در محیط ویندوز است و به همین خاطر ویندوز مارو در سطح یه کار بر معمولی نگه میدارد و کار هایی از جمله کامپایل برنامه از روی سورس و نرم افزار های رایگان کمرنگ می باشد. بنابراین بر آن شدیم لینوکسی رو سفارشی کنیم که تقریبا تمام نرم افزار های آزاد و رایگان مهندسی مکانیک و ریاضیات را داشته باشد تا علاقمندان به لینوکس و مهندسی مکانیک با قدرت این سیستم عامل آشنا شوند .

In the recent years the electrical power utilities have undergone rapid restructuring process worldwide. Indeed, with deregulation, advancement in technologies and concern about the environmental impacts, competition is particularly fostered in the generation side, thus allowing increased interconnection of generating units to the utility networks. These generating sources are called distributed generators (DG) and defined as the plant which is directly connected to distribution network and is not centrally planned and dispatched. These are also called embedded or dispersed generation units. The rating of the DG systems can vary between few kW to as high as 100 MW. Various new types of distributed generator systems, such as microturbines and fuel cells in addition to the more traditional solar and wind power are creating significant new opportunities for the integration of diverse DG systems to the utility. Interconnection of these generators will offer a number of benefits such as improved reliability, power quality, efficiency, alleviation of system constraints along with the environmental benefits. Unlike centralized power plants, the DG units are directly connected to the distribution system; most often at the customer end. The existing distribution networks are designed and operated in radial configuration with unidirectional power flow from centralized generating station to customers. The increase in interconnection of DG to utility networks can lead to reverse power flow violating fundamental assumption in their design. This creates complexity in operation and control of existing distribution networks and offers many technical challenges for successful introduction of DG systems. Some of the technical issues are islanding of DG, voltage regulation, protection and stability of the network. Some of the solutions to these problems include designing standard interface control for individual DG systems by taking care of their diverse characteristics, finding new ways to/or install and control these DG systems and finding new design for distribution system. DG has much potential to improve distribution system performance. The use of DG strongly contributes to a clean, reliable and cost effective energy for future. This book deals with several aspects of the DG systems such as benefits, issues, technology interconnected operation, performance studies, planning and design. Several authors have contributed to this book aiming to benefit students, researchers, academics, policy makers and professionals. We are indebted to all the people who either directly or indirectly contributed towards the publication of this book.

The utilization of renewable energy sources such as wind energy, or solar energy, among others, is currently of greater interest. Nevertheless, since their availability is arbitrary and unstable this can lead to frequency variation, to grid instability and to a total or partial loss of load power supply, being not appropriate sources to be directly connected to the main utility grid. Additionally, the presence of a static converter as output interface of the generating plants introduces voltage and current harmonics into the electrical system that negatively affect system power quality. By integrating distributed power generation systems closed to the loads in the electric grid, we can eliminate the need to transfer energy over long distances through the electric grid. In this book the reader will be introduced to different power generation and distribution systems with an analysis of some types of existing disturbances and a study of different industrial applications such as battery charges.

Reliable, high-efficient and cost-effective energy storage systems can undoubtedly play a crucial role for a large-scale integration on power systems of the emerging "distributed generation" (DG) and for enabling the starting and the consolidation of the new era of so called smart-grids. A non exhaustive list of benefits of the energy storage properly located on modern power systems with DG could be as follows: it can increase voltage control, frequency control and stability of power systems, it can reduce outages, it can allow the reduction of spinning reserves to meet peak power demands, it can reduce congestion on the transmission and distributions grids, it can release the stored energy when energy is most needed and expensive, it can improve power quality or service reliability for customers with high value processes or critical operations and so on. The main goal of the book is to give a date overview on: (I) basic and well proven energy storage systems, (II) recent advances on technologies for improving the effectiveness of energy storage devices, (III) practical applications of energy storage, in the emerging era of smart grids.
