He wrote eleven textbooks and monographs, was author of over 162 referred Journal articles, 199 conference papers, and supervisor of 62 graduate students. El-Hawary was a member of the editorial board of IEEE/OUP Encyclopedia of Electrical and Computer Engineering.
He was Founding Editor, Power Letters, Power Engineering Society, and Associate Editor for the three major Electric Machines and Power Systems' Journals. He was also a lecturer for the IEEE Power and Energy Society, the IEEE Industry Applications Society, and IEEE Canada. El-Hawary was Editor of IEEE Expert Now Power Engineering Series, and Electrical Power Engineering, McGraw-Hill Encyclopedia of Science and Technology.[16] [17] [18]
El-Hawary pioneered in many analytical and numerical computations to solve complicated problems of interconnected electric power systems that contains different types and technologies of generating machines, including: thermal, hydro, nuclear, solar, wind, tidal, and other renewable/sustainable/green energy resources.[19] His research interests covered most of the fields of electric power engineering, including: power flow/optimal power flow, power system operation and operational planning, power system dynamic and control,[20] power system protection and relaying, machinery design,[21] smart grids and modern networks, renewable/sustainable/green energy, fuzzy systems and its applications, and artificial neural networks (ANNs) and its applications.[22] [23] [24] [25]
