Power System Studies

Our Power System Studies

We deliver the full suite of studies required across the project lifecycle — from early design and equipment specification through utility approval, commissioning and operational troubleshooting.

Study Definition & System Modelling

Every credible study starts with a credible model. We invest the upfront effort to build accurate network models, validate input data and define the right scenarios — because the value of every downstream analysis depends on those foundations.

• Development of detailed electrical network models using ETAP / DigSILENT
• Data collection and validation (load data, equipment parameters, protection settings)
• Single line diagram (SLD) verification and system representation
• Modelling of generation sources (grid, PV, DG, BESS, hybrid systems)
• Scenario definition (normal, contingency, peak, minimum load, fault conditions)
• Alignment with utility, grid operator and project-specific requirements

Load Flow & Network Performance Analysis

Load flow studies establish how power, voltage and losses behave across the network under realistic operating scenarios — informing equipment sizing, voltage profile management and network optimization decisions.

• Steady-state load flow analysis under multiple operating scenarios
• Voltage profile assessment across network nodes
• Identification of overloads in cables, transformers and equipment
• Loss analysis and network efficiency evaluation
• Transformer loading and capacity validation
• Network optimization recommendations (reconfiguration, reinforcement, compensation)

Short-Circuit & Equipment Rating Studies

Short-circuit studies validate that switchgear, transformers, cables and breakers are correctly rated for the maximum fault current the system can produce — a foundational requirement for safe operation and utility approval.

• Short-circuit current calculations (IEC / ANSI standards)
• Equipment rating verification (switchgear, breakers, transformers, cables)
• Fault level assessment at all voltage levels
• Contribution analysis from multiple sources (grid, DG, PV, BESS)
• Circuit breaker duty and interrupting capacity validation
• Recommendations for system upgrades and protection requirements

Protection Coordination & Selectivity Studies

Protection systems should isolate faults quickly while keeping the rest of the network energized. Our protection coordination studies define settings, validate selectivity and reduce nuisance tripping.

• Protection philosophy development and review
• Relay setting calculations and coordination studies
• Time-current coordination curves (TCC) development
• Selectivity and discrimination analysis across network levels
• Review of protection schemes (feeder, transformer, generator, busbar)
• Mitigation of nuisance tripping and miscoordination risks

Dynamic, Transient & Stability Studies

Dynamic studies describe how the network behaves during faults, switching events and large disturbances — essential for systems with significant inverter-based generation, weak grid connections or sensitive loads.

• Transient stability analysis under fault and disturbance conditions
• Dynamic system response modelling (PV, DG, BESS, grid interaction)
• Frequency stability and inertia assessment
• Voltage stability analysis under varying generation/load conditions
• Fault ride-through (FRT) capability assessment
• System recovery and post-fault behaviour evaluation

Power Quality & Harmonic Analysis

Power quality studies identify and mitigate the harmonic, flicker and reactive-power issues that increasingly affect networks with inverter-based generation and non-linear loads.

• Harmonic distortion analysis (IEEE 519 compliance)
• Voltage flicker and fluctuation assessment
• Power factor and reactive power performance evaluation
• Identification of resonance conditions
• Assessment of non-linear loads and inverter-based systems impact
• Recommendations for filtering and mitigation solutions

Specialized System Studies

We also provide a range of specialized studies addressing specific operational scenarios, safety requirements or system architectures.

• Motor starting studies for large industrial loads
• Arc flash hazard analysis and safety assessment
• Earthing system studies (step and touch voltage analysis)
• Insulation coordination studies
• Reliability, redundancy and N-1 contingency analysis
• Microgrid and islanded system behaviour analysis

Grid Compliance & Utility Interface

Grid code compliance is the gateway to energization. We prepare the studies, evidence and documentation needed to satisfy utility and regulatory authorities and obtain approval to connect.

• Grid code compliance assessment for utility-specific requirements
• Interconnection studies for grid approval
• Reactive power and voltage control capability validation
• Export limitation and curtailment analysis
• Utility submission reports and technical documentation
• Support during utility review, comments and approval process

Reporting & Technical Advisory

A study is only as useful as the recommendations it leads to. Our reports translate analytical results into clear engineering guidance for the design team, EPC contractors, lenders and authorities.

• Preparation of detailed technical reports with study results and assumptions
• Identification of system risks, constraints and performance gaps
• Clear engineering recommendations for design optimization
• Support for design teams, developers and EPC contractors
• Independent technical review for lenders, investors and authorities
• Integration of study results into engineering, financial and contractual decisions

• Independent, vendor-neutral studies aligned with project owner and lender interests.
• Detailed modelling capability in ETAP and DigSILENT (PowerFactory).
• Strong familiarity with utility submission requirements across the GCC and MENA.
• Studies aligned with IEC, ANSI and IEEE standards as relevant to each project.
• Experience across utility-scale solar, hybrid systems, microgrids, industrial and infrastructure networks.
• Reports written for both engineers and decision-makers — not just analytical printouts.
• Continuity of engagement — we can support you through utility queries, EPC clarifications and commissioning observations.
