Tahir S.

Licensed Electrical Engineer | Power Systems Studies | Solar PV & BESS Power systems studies, solar PV engineering, and electrical permit packages need to be technically accurate, code-compliant, and built on real engineering judgment not assumptions. Wrong relay settings trip healthy equipment. Undersized conductors fail under fault conditions. Permit packages with missing callouts come back from AHJ with holds that cost weeks. 7+ years delivering utility-grade power system studies, solar PV design, BESS engineering, and NEC-compliant electrical documentation for utilities, EPC contractors, solar developers, and industrial facilities across the United States, Africa, and the Middle East. Real project experience across residential, commercial, industrial, and utility-scale work not academic exercises. Delivered projects include a 1 MWp hybrid Solar PV and BESS mini-grid in Somalia, World Bank-funded solar engineering packages under the LESSAP program in Liberia, and NEC-compliant permit sets for LADWP Los Angeles, Fort Pierce FL, and Horry County SC. ⚡ POWER SYSTEM STUDIES Comprehensive steady-state and dynamic analysis using ETAP, PSS/E, PowerWorld Simulator, SKM Power Tools, PSCAD, and EasyPower: ✓ Load flow, short circuit (ANSI/IEC), and contingency (N-1/N-2) analysis ✓ Protection and relay coordination with overcurrent, differential, and distance relay settings ✓ Arc flash hazard analysis and incident energy labeling per NFPA 70E ✓ Harmonic distortion, power quality, and voltage stability studies ✓ Transient and dynamic stability analysis using PSCAD and PSS/E 🌞 SOLAR PV, BESS, AND GRID INTEGRATION End-to-end solar PV and energy storage engineering from feasibility through permit-ready documentation: ✓ NEC-compliant permit plan sets residential, commercial, and utility-scale ground-mount ✓ Single Line Diagrams (SLD) and Three-Line Diagrams for AHJ, utility, and interconnection submission ✓ BESS sizing, integration, protection philosophy, and operational strategy design ✓ Solar energy yield modeling and system optimization using PVsyst, HOMER Pro, and Aurora Solar ✓ Utility interconnection studies, rapid shutdown per NEC 690, and AHJ correction support 📐 ELECTRICAL DESIGN AND DOCUMENTATION Construction-ready electrical engineering drawings and documentation packages: ✓ AutoCAD Electrical schematics, wiring diagrams, panel schedules, and cable schedules ✓ One-line and three-line diagrams engineered for AHJ submission and field construction ✓ Engineering calculations, BOQ/BOM preparation, and technical study reports 🔌 INDUSTRIAL CONTROL AND AUTOMATION ✓ PLC programming in ladder logic, function block, and structured text for industrial automation ✓ SCADA and HMI system integration for industrial monitoring and control ✓ MATLAB and Simulink modeling for power electronics, control systems, and signal processing 🛠️ TOOLS AND SOFTWARE Power Systems: ETAP · PSS/E · PowerWorld · SKM Power Tools · PSCAD · EasyPower · PSAT Solar and BESS: PVsyst · HOMER Pro · Aurora Solar CAD: AutoCAD Electrical · Autodesk Fusion 360 Simulation: MATLAB · Simulink · LabVIEW Control: PLC · SCADA · HMI · Arduino · ESP32 · STM32 Standards: NEC · NFPA 70E · IEEE · IEC · ANSI Available via Zoom across EST, PST, CST, and GMT time zones.
