Grid Compliance
Grid compliance studies verify that conventional power stations and renewable energy plants satisfy all technical requirements mandated by national transmission system operators. MEPCO evaluates active/reactive power capability (P-Q), Low-Voltage Ride-Through (LVRT), High-Voltage Ride-Through (HVRT), frequency response, and power quality at the Point of Common Coupling (PCC).

Technical Scope & Engineering Capabilities
MEPCO Engineering Projects brings specialized domain knowledge, rigorous modeling standards, and practical site experience to every assignment. Our scope covers:
- P-Q Active & Reactive Power Capability: Verifying plant reactive power supply and absorption across all active power output levels to ensure compliance with grid code power factor limits.
- Fault Ride-Through (LVRT & HVRT): Simulating symmetrical and asymmetrical voltage dips at the PCC to confirm plant ride-through without tripping and verifying reactive current injection (\(k\)-factor).
- Frequency-Droop & Active Power Response: Evaluating plant response to over-frequency and under-frequency events, verifying governor droop and primary frequency regulation.
- Synthetic Inertia & Fast Frequency Support: Evaluating inverter-based synthetic inertia and rapid active power boost capabilities.
- Power Quality Compliance at PCC: Assessing voltage unbalance, rapid voltage changes (RVC), flicker (\(P_{st}\), \(P_{lt}\)), and harmonic limits.
Software Platforms & Computational Tools
Primary Tools: Siemens PTI PSSE and PSCAD/EMTDC.
Secondary Tool: ETAP Grid Compliance Module.
Applicable Standards & Grid Codes
Grid Codes: Egyptian Electricity Transmission Company (EETC) Grid Code, Saudi Electricity Company (SEC) Transmission Code, UAE Grid Codes (DEWA/SEWA/TRANSCO), ENTSO-E Requirements for Generators (RfG).
Methodology & Project Delivery Workflow
Our engineering delivery aligns with MEPCO’s structured 6-stage project execution framework, ensuring quality throughout input verification, design modeling, and client handover:
- Stage 01 — Scope & Criteria Definition: Establish study boundaries, utility tie-in data, single-line diagrams, and client objectives.
- Stage 02 — Data Audit & Modeling Assumptions: Collect, verify, and validate manufacturer datasheets, impedance tolerances, and site operating configurations.
- Stage 03 — Simulation Model Development: Build detailed, validated mathematical digital models in specialized power software.
- Stage 04 — Computational Analysis & Verification: Execute base-case and contingency scenarios, conducting rigorous internal peer reviews.
- Stage 05 — Client Review & Approval: Present study findings, address technical comments, and participate in technical clarification sessions.
- Stage 06 — Final Handover: Deliver formal certified engineering reports, executive summaries, and native simulation model files.
