- ItemOn Grid photovoltaic System in Palestine: A Case Study of techno- economic impact for Dar Salah School(Al-Quds University, 2023-04-29) Bassam Odeh Salameh Saleem; بسام عوده سلامه سليمThe increase in electric energy consumption and the immediate need for electricity in Palestine leads us to strengthen and develop the electric power system. In this work, the photovoltaic system at Dar Salah School for Boys was studied, which was installed on 1/1/2020. My work focused on the installation, features, determination of system performance and output, and analysis of economic feasibility and efficiency of this system using Ret screen & PV System. Upon completion of the system performance evaluation study, it was found that the system outputs are lower than the expected for technical reasons and external factors that were not taken into account when installing the system. These problems facing the system were identified and the ways to address them were put forward to maintain the expected system productivity. The system represents a good investment case for the Ministry of Education because it almost covers the school's energy needs according to the percentage agreed upon with the company and the price per kilowatt .hour with the Electricity Company. It represents a good investment case for many companies to exploit renewable energy sources if there are encouraging government laws and regulations.
- Item" Assessment of using wind power to charge electric vehicles batteries(Al-Quds University, 2022-10-22) Osama Farid A.W Eghrayeb; اسامة فريد اغريبأصبح التقدم التكنولوجي مثيرًا للإعجاب، حيث يفكر الجميع في وسائل البقاء على هذا الكوكب ويأخذ زمام المبادرة في حل المشكلات التي يتم توقعها مسبقًا من خلال علوم التكنولوجيا الحديثة. واحدة من المشاكل الكبرى التي من المتوقع حدوثها هي نفاد الوقود الأحفوري المستخدم لتوليد الطاقة الكهربائية خلال السنوات القليلة المقبلة، لذلك كانت جميع الدول المتقدمة قد أخذت زمام المبادرة لتطوير أنظمة جديدة يمكن أن تزود العالم بالكهرباء. ومن أبرز هذه المصادر المكتشفة الخلايا الشمسية والتوربينات، حيث تعتبر هذه المصادر من أفضل المصادر المكتشفة حتى الآن والمستخدمة في توليد الطاقة في جميع دول العالم. يعتبر قطاع النقل من أهم الركائز في حركته، حيث يعتمد على الديزل والبنزين المستخرج من الوقود الأحفوري الذي على وشك النفاد. لذلك فكر المهتمون بقطاع النقل باستغلال مصادر الطاقة البديلة لتشغيل المركبات على الطاقة المستخرجة منها، حيث تم تطبيق هذه الأنظمة وتركيبها على المركبات وكان أداؤها جيداً. حتى توصلوا في أحدث إصداراتهم إلى أن تعمل المركبات بالكامل أعلى الكهرباء عن طريق تخزينها في بطاريات دون الحاجة إلى محركات احتراق داخلي التي تعتمد بشكل كامل على الوقود. في هذا العمل، نوضح كيف يمكن الاستفادة من طاقة الرياح عن طريق دراسة إمكانية تركيب ٤ توربينات لتوليد الطاقة من الرياح وتزويدها ببطارية مركبة كهربائية مع مراعاة الموقع المناسب لها بحيث لا تعمل على اضافة اي قوى تعيق سير المركبة. القوة المحسوبة التي تحتاج إلى شحن بطارية المركبات باعتماد سرعة رياح 15 م / ث كانت 0.138 كيلوواط، ولكن عندما تزيد السرعة عن 23 م / ث، ستكون الطاقة المولدة أكثر من 1 كيلوواط. عندما تعمل التوربينات معًا، فإن الكهرباء المولدة التي سيتم تخزينها في البطارية ستكون كافية للوصول الى نقطة التعادل بين معدل التفريغ ومعدل الشحن (92.6 كم، 58 كيلوواط ساعة) وبعدها تبدأ بالشحن الإيجابي (النقطة التي بعدها تكون كمية الكهرباء المولدة أكبر من الكمية المستهلكة).
- Itemreneable energy laws and policies in Palestine(Al-Quds University, 2020-11-21) Ali Mustaffa Mohammed Arouri; علي مصطفى محمد عروريThe energy issue is an important indicator of the progress and independence of nations, as the world lives these days in a race for energy productivity. For years, the world has turned to renewable energy, as governments have contributed significantly to stimulating investment in renewable energy. Many countries have enacted laws that have brought in large investments in this area and have worked to raise their productivity in alternative energy. We here in Palestine suffer from the control and control of the (Israeli) side of the energy, so that 87% of the electricity consumed in Palestine comes from the Israeli-Qataria company. Therefore, we had to turn to a kind of autonomy in producing energy so that we can get out of this control and this control. In this research, i reviewed the laws of certain countries in the field of renewable energy and also reviewed the volume of investments in this field they have and the extent of their influence on laws and regulations, especially in the case of the Kingdom of Jordan. On the other hand, we review the aspects and policies related to renewable energy in Palestine and the size of investment in the field of renewable energy to produce results that show the importance of laws and facilities in raising the productivity of alternative energy. I also reviewed in the end a set of recommendations that would contribute to looking at the matter well and drawing the attention of the competent authorities.
- ItemTechno-Economic Feasibility Analysis of Solar-Wind Energy Conversion System Utilizing Genetic Algorithm(Al-Quds University, 2019-08-20) Woroud A. O. Alnatsha; ورود عبد المنعم النتشهIn recent years, the interest in using renewable energy sources has been growing globally since they are considered as a key solution to satisfy the world increasing demand for energy and for reducing the global carbon emission. Palestinians have previously started utilizing solar energy for heating water for domestic and industrial uses. Recently, a strong trend has been made to use solar energy to convert it into electrical energy using solar cells. In addition, the geographic and topographic configuration and the prevalence of dominant wind can be a good potential for small and medium wind energy conversion systems (Turbines). The objective of this study is to simulate and optimize the renewable energy system of Palestine Polytechnic University (PPU) campus that is located in the Hebron city which consists of 230 kW photovoltaic energy conversion, by adding wind energy conversion system and changing the current system to on-grid hybrid renewable energy system HRES. This study is based on a configuration of (HRES) by using a genetic algorithm (GA) which enables the identifications of the optimum size that meets the possible demand along with most feasible economical values and ensuring the highest system reliability. The simulation results clearly show that the HRES is a more economical configuration than single renewable energy systems which has a total net cost of (410,743 $) and a cost of energy (COE) of (0.043) $/kWh.
- ItemRF and Piezoelectric Energy Harvester by applying a Threshold Voltage Rectifier Cancellers(Al-Quds University, 2021-01-21) Hashem M. H. Abu Aram; هاشم محمد ابو عرامIn this thesis study about the RF are shown and Piezoelectric Energy Harvester and focused on the problems of using rectifier circuit represented by: threshold voltage higher than input voltage, Reverse current from the storage damage the current rectifier, to improve the efficiency of the system, anew rectifier circuit that reduce the drop voltage were proposed, and protection the reverse current with hybrid energy harvesting from RF and piezoelectric to provide DC voltage and improve the system. The simulation results showed an increase efficiency of rectifier circuit to 41.7% compared to the efficiency reached by researchers previously and The voltage reaches stability in a brief period of time, which is estimated to be nanoseconds. Those two points were an obstacle in the path of researchers previously, those problems are solved, and then energy from many sources could collect to power any smart system.
