. Mohammed Safiuddin received B.E. (Electrical) degree from Osmania University, Hyderabad, India in 1959 and MSEE degree from the University of Illinois in 1960. Later he received MBA and Ph.D. degrees from the University at Buffalo [SUNY], in 1971 and 1982 respectively.

Having worked as Junior Engineer in Andhra Pradesh State Electricity Board (India) for over a year before arriving in the USA, he joined the Systems Control Department of Westinghouse Electric Corporation, Buffalo, New York in June of 1960 as an Associate Engineer. He progressed through the ranks of Engineer, Senior Engineer and Fellow Engineer positions to become Manager, Product/Strategic Planning in 1982 in the Power Electronics and Drive Systems Division and was later appointed Technical Advisor in the Marketing Department of the same Division. His interests in continuing education has kept him in close contact with the University at Buffalo (SUNY), where he did part-time teaching in early sixties and then served as Adjunct Associate Professor (‘77-‘91), and Research Professor [’91-‘10]. He is currently Research Professor Emeritus [Advanced Technology Applications] in the Electrical Engineering Department of University at Buffalo [UB]. He is also President of STS International, a technology service firm he established in September 1985. His areas of technical interests cover static power conversion and optimal control systems as applied to industrial processes, renewable energy, and Smart Grid power systems. He has been awarded 10 patents in this field and has dozens of technical papers and conference presentations to his credit.

Honors and awards bestowed upon him include: Roscoe Allen Gold Medal, Osmania University (India), 1957; Pi Mu Epsilon Society, Univ. of Illinois, 1960; Graduate Fellowship, Univ. of Illinois, 1964; Beta Gamma Sigma Society, University at Buffalo, 1971; Invited consultant to Council of Scientific and Industrial Research (India) under United Nation's Development Program sponsorship (1992); IUSD Award of Merit, IEEE Industry Applications Society, 1992, for contributions to industrial control technologies and excellence of service to the Society; Fellow, IEEE (1993) with citation "For contributions to advanced industrial control systems for processes and electric drives, and for leadership in continuing education"; Elected "Eminent Engineer" member of Tau Beta Pi honor society, at SUNY at Buffalo, for engineering (1993); Meritorious Achievement Award in Continuing Education, IEEE-Educational Activities Board (2000), "for exemplary and sustained contributions in continuing education worldwide."

Test Bed for a Cyber-Physical System (CPS) Based on Integration of Advanced Power Laboratory and eXtensible Messaging and Presence Protocol (XMPP)This paper illustrates integration of Advanced Power Laboratory with SupervisoryControl and Data Acquisition (SCADA) as a test bed for a Cyber-Physical System (CPS).Such integration has large-scale application in smart grid realm as well as in powerengineering education and professional development for energy professionals. As aresult, a complete smart grid training system including generation, high voltagetransmission, and medium and low voltage distribution was developed.Integration of advanced power laboratory has been performed with Lucas-Nülle (LN)smart grid training systems and Schweitzer Engineering Laboratories (SEL) protectiverelays at the joint xxx and xxx Smart Grid Laboratory at xxx. One of the key features ofthe test bed is utilization of eXtensible Messaging and Presence Protocol (XMPP). Theuse of XMPP allows multiple users, devices, and applications to share criticalinformation in power applications. The laboratory system includes a model of long-distance transmission line combined with fault protection system by SEL. During thefault conditions, SEL relays operate as intended to clear the fault. Information of thesystem state is collected from Smart Grid laboratory sensors (smart meters and relays)and transferred via MODBUS TCP protocol to Supervisory Control and Data Acquisition(SCADA) system to display parameters of the system’s state.The XMPP system interface establishes secure session with registered users, devices, andapplications. The link provides metadata to enable sensor data to be viewed by others.These notifications can be directed to operators that can control other equipment inresponse to the event. The XMPP link utilizes Transport Layer Security (TLS) to encryptthe data links. Actions by an operator can also be sent to remote devices extending theSCADA capability over any wired or wireless networks including the Internet.The use of XMPP provides multicast capabilities and provides secure communicationswithout the need for a Virtual Private Network (VPN). XMPP has been used to providesecure session initiation for many years but had not been used in CPS power applications.The capabilities can be used with mobile devices to provide alerts to maintenance andoperations personnel. The event can also be shared with emergency response personnelwho are trusted to receive this information.The integrated CPS test bed provides real-time data, including power flow andinformation flow, to power system operators and other authorized personnel, which aidsthem in making more effective and intelligent decisions.The test bed provides educational and research experience to undergraduate and graduatestudents and significantly raises their interest in energy field and broader areas of cyber-physical systems and provides unique experience with important aspects of the moderngrid.
