Hybrid Microgrid Power Quality Management – Erawin Oil Field, Murzuq Basin, Libya
Project Context: Erawin Oil Field Development
Location: Murzuq Basin, Libya
Sector: Oil & Gas | Hybrid Energy
Architecture: Solar PV | BESS | Diesel Backup
Project Background

GSC developed architecture and control concepts for a remote oilfield hybrid power system in the Murzuq Basin, Libya, integrating solar PV, battery storage and conventional generation. The engineering focus was dependable off-grid operation, power quality, fuel reduction and operational resilience.

Project Objectives
  • Deliver stable and reliable off-grid power for critical oilfield operations.
  • Increase renewable-energy contribution while retaining dependable backup generation.
  • Address voltage instability, harmonics and interruptions.
  • Establish continuous monitoring and real-time power analytics.
  • Create a scalable engineering framework for future remote hybrid systems.
Engineering / Delivery Challenges
  • Critical off-grid loads in a remote operating environment
  • Voltage, frequency and harmonic-quality requirements
  • Coordination between intermittent renewable generation, storage and conventional units
  • Need to reduce diesel dependence without sacrificing reliability
GSC Engineering Approach & Methodology

GSC defined a hybrid microgrid architecture and control philosophy integrating solar PV and BESS with existing generation. The approach included a power-quality assessment and continuous-monitoring concept, consideration of corrective technologies such as SVC, flywheel storage, UPQC and power-factor correction, and a PDCA-based continuous-improvement methodology.

Sustainability / Business Impact

The case demonstrates GSC's approach of connecting engineering decisions with reliability, lifecycle value, operational performance and sustainability. Where quantified results are shown above, they are retained from the underlying project material and should not be altered by the website developer.

Lessons & Transferable Value

Remote hybrid systems cannot be designed around energy balance alone. Stability, power quality, control coordination, monitoring and corrective capability must be engineered together if renewable penetration is to increase without undermining critical operations.
