Adaptive Control of a Hybrid Microgrid With Energy Storage System
M. A. Ebrahim;Ali M. El-Rifaie;Bassant Ahmed Bahr;H. E. Keshta;Mahmoud N. Ali;M. M. R. Ahmed
The growing integration of Renewable Energy Resources (RER) and Energy Storage Systems (ESSs) into Hybrid Microgrids (HμGs) downsizes the system inertia that reduces the system ability to maintain the frequency and voltage within the standard levels. To tackle this challenge and enhance the dynamic response of HμGs, PID based model reference adaptive control (MRAC), for the synchronous generator (...Show More
This study introduces a novel risk measurement and control framework tailored to optimize the stochastic energy trading strategy of a solar storage system at Egypt’s Siwa solar station. By integrating key risk measurements Shortfall Probability (SP), Value at Risk (VaR), and Conditional Value at Risk (CVaR)–into a stochastic optimization model, this framework caters to diverse risk preferences and...Show More

In the recent years, residents in Kuwait have suffered from the increase of electrical power outages. This issue obstructs the daily lives of residents, especially the ones that rely on medical equipment at their own houses. As recently reported by the Ministry of Electricity, Water and Renewable Energy in Kuwait, the average duration of electrical power outages in Kuwait is approximately three ho...Show More
Optimal Allocation of TCSC Devices in Transmission Power Systems by a Novel Adaptive Dwarf Mongoose Optimization
Hashim Alnami;Ali M. El-Rifaie;Ghareeb Moustafa;Sultan H. Hakmi;Abdullah M. Shaheen;Mohamed A. Tolba
This paper introduces a novel Improved Dwarf Mongoose Optimizer (IDMO) based on an Alpha-Directed Learning Process (ADLP) for dealing with different mathematical benchmark models and engineering problems. The dwarf mongoose’s foraging behavior motivated the DMO’s primary design. Three social groupings are used: the alpha group, babysitters, and scouts. The unique suggested solution includes an upg...Show More
Modified Gradient-Based Algorithm for Distributed Generation and Capacitors Integration in Radial Distribution Networks
Ali M. El-Rifaie;Abdullah M. Shaheen;Mohamed A. Tolba;Idris H. Smaili;Ghareeb Moustafa;Ahmed R. Ginidi;Mostafa A. Elshahed
With the use of cutting-edge demand management at the system or home level and powerful network reconfiguration tools, smart grids are expected to introduce advanced hardware and software resources to strengthen the operation of power systems. This article describes a Modified Gradient-Based Optimization (MGBO) algorithm for Distributed Generation (DG) and capacitors integration in distribution fe...Show More
Fuel Cell Parameters Estimation via Marine Predators and Political Optimizers
Ahmed A. Zaki Diab;Mohamed A. Tolba;Ayat Gamal Abo El-Magd;Magdy M. Zaky;Ali M. El-Rifaie
Proton Exchange Membrane Fuel Cells (PEMFC) is considered a propitious solution for an environmentally friendly energy source. A precise model of PEMFC for accurate identification of its polarization curve and an in-depth understanding of all its operating characteristics attracted the interest of many researchers. In this paper, recent meta-heuristic optimization methods have been successfully ap...Show More
In remote areas, it is always preferred to generate electricity using wind power. A double-fed induction generator has always been a good choice to generate electric power from wind. It is not easy to detect internal short circuits on stator windings especially for those occurring within a few turns of the stator windings. The short circuit currents flowing in such cases cannot be determined by tr...Show More
Automatic calibration system for electrical sourcing and measuring instruments
2013 12th International Conference on Environment and Electrical Engineering
Year: 2013 | Conference Paper |
Cited by: Papers (5)
Automation in measurements has extreme range of metrology applications which include instruments controlling, measurement processing and results analysing. As, commercial software is not suitable for the highly accurate metrological laboratories, the construction of an appropriate software is one of the priorities for these laboratories; consequently, a new automatic system has been established in...Show More
A novel measurement technique for extra high voltage bus bar fault detection
2012 11th International Conference on Environment and Electrical Engineering
Year: 2012 | Conference Paper |
This paper introduces a new fault detection tool for Extra High Voltage (EHV) busbars. The new tool is to be used by extra high speed digital relays to detect busbar faults besides differentiating between close up line faults and busbar ones. The suggested tool uses a new technique that squares both of the instantaneous voltage signal and its complement to produce a unity relation in normal operat...Show More
