إن التكامل بين مصادر الطاقة المتجددة المختلفة, بالإضافة إلى تحرير أسواق الطاقة الكهربائية من القيود المؤثرة على استقرار و استمرارية تأمين التغذية للمستهلكين يؤكد الحقائق القائمة في أنظمة الطاقة الكهربائية الحديثة. إن زيادة مشاركة مصادر الطاقة المتجددة ضمن نظم الطاقة يتعلق بتباين العرض و الطلب. لذلك يعتبر تخزين الطاقة كأحد الحلول المستخدمة لتحقيق الاستقرار في إمدادات الطاقة الكهربائية للحفاظ على التوازن في توليد الطاقة المطلوبة و ضمان عدم انقطاعها عن المستهلكين. و في سياق التنمية المستدامة و نضوب موارد الطاقة التقليدية فإن مسألة نمو إنتاج الطاقة الكهربائية من الطاقة المتجددة مرتبط إلى حد كبير بالقدرة على اقتراح حلول جديدة لتخزين الطاقة و تكييفها. و تشير التطورات الاخيرة في تكنولوجيا الهيدروجين و تطبيقات الطاقة المتجددة إلى إن هذه التقنيات واعدة لتحول الاقتصاد إلى اقتصاد قائم على الهيدروجين, بالاعتماد على استخدام الهيدروجين لشبكات الطاقة الكهربائية العامة و في قطاعات النقل, يناقش هذا البحث أهمية إنتاج الهيدروجين و دوره كحامل للطاقة, و عملية التحليل الكهربائي و القيمة الاقتصادية لإنتاج الهيدروجين و خاصة من تكنولوجيا الطاقات المتجددة الشمسية-الريحية. إن الدراسات التقنية و الاقتصادية وجهت لإيجاد نظام لتخزين الهيدروجين على المدى الطويل الأجل لاستخدامه في توليد الطاقة الكهربائية. و يزداد إنتاج الهيدروجين بفترات إنتاج متعلقة بارتفاع أو انخفاض الطلب على الطاقة, و يمكن أن يباع مباشرة إلى مشغلي الشبكة أو عن طريق خزانات (اسطوانات) مليئة بالهيدروجين. و التحقق من الاستخدام الآمن للتقنيات القائمة على استخدام الهيدروجين لتخزين و توليد الكهرباء على المدى الطويل. و تشير النتائج إلى أن هناك مصادر كافية موجود لإنتاج الهيدروجين من الطاقة الشمسية و الريحية. و مع ذلك تعتمد أسعار الهيدروجين اعتمادا كبيرا على اسعار الطاقة الكهربائية.
The integration of various renewable energy sources as well as the liberalization of electricity markets are established facts in modern electrical power systems. The increased share of renewable sources within power systems intensifies the supply variability and intermittency. Therefore, energy storage is deemed as one of the solutions for stabilizing the supply of electricity to maintain generation-demand balance and to guarantee uninterrupted supply of energy to users. In the context of sustainable development and energy resources depletion, the question of the growth of renewable energy electricity production is highly linked to the ability to propose new and adapted energy storage solutions. Recent advancements in hydrogen technologies and renewable energy applications show promise for economical near to conversion to a hydrogen-based economy. As the use of hydrogen for the electric utility and transportation sectors. This paper briefly discusses provides a historical perspective for hydrogen production and the role of hydrogen as an energy carrier, discusses hydrogen economy, the process of electrolysis for hydrogen production (especially from solar and wind technologies). A comprehensive techno/socio/economic study of long term hydrogen based storage systems in electrical networks is addressed. the excess produced hydrogen during high generation periods or low demand can be sold either directly to the grid owners or as filled hydrogen bottles. The affordable use of Hydrogen-based technologies for long term electricity storage is verified. The results indicate that ample resources exist to produce Hydrogen from wind and solar power. However, hydrogen prices are highly dependent on electricity prices.

Three identical gable-even-span greenhouses were designed, constructed
and installed at the Agricultural and Veterinary Research Station of King
Faisal University in order to produce cucumbers during the winter season.
These experimental greenhous
es were covered by ٠,٨mm thick fiberglass
reinforced plastic. Two different solar heating systems were designed, built and
employed to heat the ambient air temperature inside the greenhouses. The
design of the first one was a surface heating system suspended and fixed on the
southern side of the gable roof of one greenhouse. The second solar heating
system was a solar panel, which was designed, built and situated outside of the
other greenhouse.
In this paper, we have suggested the STATCOM
(STATic synchronous COMpensator) to connect PV-solar (or
wind) frame to the power system for the Hassia industrial city
which we chose as a case study. This frame will provide the city
with the required power, improve the power quality and inject
the redundant to the power system.
The main objective of this research is to estimate the potential electrical power that can be extracted from closed and out-of-service oil wells situated in the north-eastern part of Syria. The research shows that using Organic Rankine Cycle (ORC) wi
th Isobutane as working fluid can produce net power output under certain conditions. The geothermal cycle used brine solution to
absorb the ground heat.
This paper treats the issue of wind energy storage, mechanically, using the flywheel
device. We control the speed of the wind turbine and the flywheel by means of traditional
PID controllers. These controllers are designed depending on the system m
odel and its
parameters. Speed control is achieved by electromagnetic rotor flux orientation as called
vector control. Speed reference value of the wind turbine will be generated in order to track
the maximum power point. The flywheel reference speed is generated based on a second
order filter of power which is considered as a new contribution in this field of research.
Frequency converters are not modeled but we only consider the control strategy. The
results of modeling and simulation in Matlab satisfy the power smoothing issue and reflect
the importance of this study.
Batteries are energy storage devices that are particularly useful for powering
small portable devices like phones, laptops and entertainment devices as well as
mobility devices that travel over the earth's surface, through water and air. During the
night, or during a period of low solar irradiation, energy is supplied to the load from
the battery in solar electrical Power Systems, and that provides Continuity of power
supply, and on the other hand boosts the Reliability of the system.
