I'm Sajjad Uddin Mahmud — an electrical engineer working at the seam between the research bench and the working grid. At Schweitzer Engineering Laboratories I develop and validate integration and automation features in protection products: defining specifications, building functional tests and system validation processes, and diagnosing the communication problems that show up in the field.
My doctoral research at Washington State University's SCALE Lab, advised by Dr. Anamika Dubey, builds multi-stage probabilistic models that quantify how extreme cold weather degrades gas-fired generator performance — the kind of failure that turns a cold snap into a blackout. Before that I spent three years commissioning 50 MWp+ of industrial rooftop solar across Bangladesh, and a year and a half teaching undergraduate circuits and electronics.
Protocols and probability distributions on one side, relays and rooftops on the other. Outside all of it, I find quiet in photography and art.
Work Experience
- Maintaining advanced technical knowledge and skills to contribute to the development and enhancement of integration and automation features in SEL products.
- Defining, developing, and analyzing product specifications, functional tests, and system validation processes.
- Diagnosing customer-reported problems with integration and communication features, and documenting issues for developers.
- Built a multi-stage Bayesian probabilistic framework to model gas-fired generator failure risk under extreme winter weather.
- Integrated NERC GADS real grid-operator outage data with NOAA weather data and ISO demand data to quantify winter-weather-dependent generator failure probability.
- Findings inform both short-term operational risk assessment and long-term resource-adequacy planning for extreme winter weather events.
- Contributed to Dynamic Line Rating (DLR) research for power transmission planning, applying EPRI's DLR analysis tools to weather data to generate synthetic multi-year DLR datasets for transmission lines.
- Performed comparative analysis between synthetic and real-world DLR datasets to evaluate model accuracy, supporting both short- and long-term transmission planning use cases.
- Explored methods for applying long-term synthetic DLR data to transmission planning decision-making.
- Gained hands-on experience with power system communication protocols — GOOSE, PTP, and Sampled Values — through experimentation and testing on SEL relays.
- Developed Python automation scripts that streamlined team workflows and significantly reduced task completion times.
- Established a performance testing system for 87L Line Current Differential Protection on SEL relays.
- Assessed technical designs and oversaw installation and commissioning of 50 MWp+ industrial rooftop solar projects, with ongoing monitoring of operations and maintenance.
- Managed a field team of technicians across all project phases — from feasibility assessment and commissioning to post-installation monitoring.
- Assisted in developing technical standards for industrial rooftop solar projects in Bangladesh.
- Organized and led 20+ training programs across Bangladesh, building capacity of 400+ government officials on solar home systems and solar street lighting, with full ownership of logistics, materials, and coordination.
- Collaborated with local industries, EPC companies, and international consultants from Gopa-Intec, the World Bank, and KfW.
- Designed and delivered undergraduate lectures in Electrical Circuit Analysis, Electronic Devices and Circuits, Digital Logic Design, Managerial Accounting, and Calculus.
- Redesigned laboratory manuals for Electrical Circuit Analysis and Electronic Devices and Circuits courses.
- Mentored 70+ students, providing academic and personal development guidance throughout their undergraduate studies.
- Performed optical fiber network troubleshooting through identification, solving, and reporting of technical issues.
