The number of Photo-Voltaic arrays being installed in electric systems is increasing. One of the basic challenges in using these arrays is the shifts in produced power, due to varying environmental conditions, mainly solar irradiation. This challenge is bigger under for cells under partial shading (cloud, dirt, etc.). Therefore, there is a need for an algorithm that will always track the maximum power point (MPP) of the cell. There are...

This project deals with wireless power transference to charge a drone, using the Electromagnetic Induction Principle. It presents the main wireless charging standards that are in use today and the characteristics of today’s drone batteries. The project includes explanation on the source of power we had planned to use – high voltage line – but mostly deals with the power transference.  It uses a DC voltage from the system on...

Due to Amendment 16 for the Electricity Market Law, which was confirmed at 18.07.2018, a privatization process of vast portions of the electricity manufacturing has been debuted. The Goal of the process is enabling the privatization of the power generating systems and allowing the construction of new, private, power generating systems, all as part of the power ministry’s greater goal – 30% of renewable energy consumption in Israel up until...

In this project we modeled a power system that is powered by photovoltaic sources. We simulated a possible power step that can be caused by nature interferences, to see how it affects the system frequency. In order to maintain a stable system frequency and to minimize disturbance by the power step, we suggest to add an energy reservoir that will provide power to the system in case of interference. In...

We have built a model of Israel electricity transmission system to produce it to anyone that would like to observe, understand, and analyze the electricity transmission system. While there is a model which is used by the IEC (Israel electric corporation), it is classified for security and business reasons and an open to the public one was needed. The model is separated into two parts: The geographical model – a...

One of the biggest challenges facing the world today is the evolving power grid. As a response to anthropogenic climate change, countries are trying to integrate renewable energy and storage into modern power grids. Because of the inherent decentralization of these power sources, there are many actors involved in this process: from a home-owner installing solar panels on their roof, to a city forming a microgrid. In this project, game...

The goal of the project is to design a proper and modern school campus electrical system consisting of several buildings and open spaces. Designing an electrical system for a school campus is a complex process that requires a combination of complying with the Electricity Law and its regulations, complying with the Ministry of Education’s regulations, efficient and convenient planning, and economically sustainable planning. Such planning will ensure a safe and...

Due to rise in renewable energy storage, many issues regarding stabilizing the electrical grid frequency become more complex, the main solution for this problem is energy storage. In this project two existing technologies were reviewed and compared:  Li-Ion batteries and Super-Capacitors.

Abstract The project’s goal is to find an optimal location to connect a renewable energy sources to a distribution network that simulates an urban electricity network. in the first part of the project, a distribution network was planned according to accepted planning criteria. The choice of network components (transformers, transmission lines) was made according to data of real components. The network modeling and simulations were done using XPLORE PSSE simulation...

In the power systems community, there is active research on different aspects of integration of renewable energy sources. One such aspect is the effect of renewable sources on voltage profiles and power flow. A different aspect is the dynamics of the system, where the effects on power quality and system stability are studied. In this project we focused on the subject of system stability and the role of energy storage...

הצורך בשינוי פרמטרי מבוקר של תמסורת עולה רבות בתחומי התקשורת ואלקטרוניקת הספק. שילוב של קבל משתנה במערכת מהווה כלי חשוב שבאמצעותו ניתן לשפר את פעולת המעגלים בכל הנוגע לרעש, רובוסטיות ולעיתים אף הקטנת נפח ומשקל. בפרט, בהיבט של אלקטרוניקת הספק, ניתן להשתמש בקבל משתנה כחלק מחוג בקרה של ממיר מתח מבוסס תהודה. שיטה זו מבטלת את הצורך בבקרת תדר ומפחיתה הכנסת תדרים רבים לתוך הממיר אשר גורמים להיווצרות הפרעות אלקטרומגנטיות...
