Grid-code compliance & hosting capacity

A clause-by-clause interconnection compliance check plus the hosting capacity of the connection point. The engine reads the study products (load flow, harmonics, PV power quality, protection, LVRT, islanding, short circuit, PQ envelope), compares every clause against the selected standard profile, and reports — for each clause that does not pass — which clause it is, by how much it misses, and what to change.

Tier 1 · Project and standard profile

Case nameStandard profile (engine input gridCodeCheck.profile)Voltage level (engine input gridCodeCheck.voltageLevel)

Tier 2 · Grid and main equipment

Grid voltage (kV)Grid short-circuit power Ssc (MVA)Transformer rating (kVA)Transformer impedance uk (%)Load (kW)Load power factor cos φTaken from the load node (cosPhi); the engine does not back-calculate the power factor from a kvar value.Cable length (m)Cable section (mm²)Load harmonic current ratio h3,h5,h7,h9,h11 (%)Example condition — the spectrum of the non-linear load, comma-separated. Replace it with the actual spectrum of your load; the engine consumes it and never invents it.

Tier 3 · Distributed energy resource (DER)

DER type (engine input hostingCapacity.derType)DER rated power (kW)The hosting-capacity search starts from this connection point and bisects on the first binding constraint.Point of connection (node tag)DER power factor

Tier 4 · Criteria and basis

Voltage upper limit (pu)Voltage lower limit (pu)Leave empty to keep the engine default (lower voltage bound not checked).Branch loading limit (%)Short-circuit level limit (kA)If no Icw is known, leave this empty — the engine then reports the short-circuit clause as “unknown” instead of assuming a limit.

Reference connection model: this page assembles a standard MV-to-LV interconnection model from the parameters in the four tiers below (grid source → MV switchgear → transformer → LV busbar → load → DER). Every value is your input; every verdict is computed by the engine. Nothing is written back to your scheme.

The engine computes the network; this page only displays what comes back. Every clause verdict comes from the engine, and missing data is shown as “—” rather than 0.
