Hands-on experience with software such as PSCAD, PSS/E, ETAP, and DigSILENT is required.

Key Responsibilities:

• Conduct grid integration studies including transient and steady-state stability, voltage stability, harmonic, power quality, LVRT, and Fault Ride Through analyses.
• Perform short circuit analysis and determine switchgear and circuit breaker sizing according to standards.
• Carry out insulation coordination studies involving cable, transformer energization, reactor energization, TRV, lightning strike, and transient overvoltage studies using PSCD or similar tools.
• Perform arc flash analysis adhering to international standards.
• Conduct contingency analysis for grid component design.
• Perform ferro-resonance studies related to transformers and EHV cables.
• Analyze secondary arc current extinction for auto-reclosure studies.
• Select surge arresters based on residual voltage and energy levels.

Renewables:

• Load flow studies for assessing network overloading with RES capacity additions.
• Identify reactive power requirements for various RES scenarios.
• Model renewable sources such as Solar, BESS, and Wind.
• Assess operational challenges of different RES technologies.
• Verify grid code compliance before energization under various operational scenarios.

Industrial:

• Perform motor acceleration and re-acceleration studies for process requirements.

General:

• Familiarity with IEC, IEEE, DEP, and other standards.
• Analyze technological solutions for system studies.
• Estimate input parameters for studies when data is unavailable.
• Interpret country-specific grid codes, especially Middle East standards.
• Identify issues during grid integration and propose solutions.

Preferred Skills:

• Design of power generation mixes for microgrids and battery storage using HOMER or similar software.
• Protection relay selection and coordination studies.
• Modeling of Phase Shifting Transformers.
• Experience with customer and utility interactions for grid impact approvals.
• HVDC, STATCOM projects, including electromagnetic compatibility studies.
