Commission Regulation (EU) 2016/631 — RfG
The grid-code framework and compliance process; Article 43 covers compliance simulations.
02 / MODEL / SIMULATION / ASSESSMENT
Simulation reports.
Evidence for grid connection.
We build a controlled simulation of plant behaviour during voltage and frequency deviations and power-control demands. For relevant power-generating modules, we deliver a traceable report to the scope agreed with the distribution system operator for the UPOS or UTP process.

SERVICE SCOPE
From source data to a result that can be reviewed.
We run the work in our own developed simulation platform. Each run keeps the model version, input data, assumptions, scenario and assessment criteria together, making the result and any remaining data gaps explicit.
01
Model and inputs
We assemble the electrical and control model from manufacturer data, control settings, the network equivalent and connection conditions.
02
Required scenarios
Depending on scope, we simulate FRT including UVRT and OVRT, LFSM-O and LFSM-U, Q(U), the PQ capability diagram, power factor, P(U), power control and reconnection.
03
Compliance assessment
Voltage, frequency, active-power and reactive-power traces are compared with the project-specific criteria and linked to the model and scenario version.
04
Simulation report
We deliver the results, plots, requirement matrix, assumptions and a clear record of missing input data.
WHAT TO PREPARE
Inputs for a useful start.
- Connection conditions and the simulation scope requested by the system operator
- Single-line diagram, transformer data and network equivalent
- Inverter, PCS, plant-controller and protection models or parameters
- Operating modes, limits and available manufacturer data
WHAT WE DELIVER
An output you can use.
A version-controlled simulation report with model and input references, scenario-by-scenario assessment, graphical outputs and a list of missing evidence.
The report is a technical simulation deliverable, not a certificate or a system-operator decision. Scope depends on the module, connection conditions and the relevant operator requirements. Missing values are not presented as confirmed inputs.
ASSESSMENT FRAMEWORK
Requirements applied to the actual project.
Czech PPDS, Annex 4
Connection, model, test and simulation requirements as applicable to the specific project and system operator.
EN 50549-1 and EN 50549-2
Technical requirements for generating plants connected in parallel with LV and MV distribution networks.
IEC TS 63102:2021
Grid-code compliance assessment methods for wind and photovoltaic power plants, including simulation and validated models.
IEC 61400-27-1 and IEC 61400-27-2
Models and model validation for wind turbines and wind power plants, used only where relevant to the technology and scope.
PRACTICAL DETAILS
Questions we are
often asked.
Does every plant need a simulation report?
Not automatically. Evidence, testing and simulation depend on module type and category, connection conditions and the relevant system operator requirements. We confirm the actual scope first.
What does own simulation platform mean?
We develop and maintain the modelling and assessment tool ourselves. This allows controlled versions, transparent assumptions and tailored scenarios without claiming accredited-laboratory or certification status.
What if operator or manufacturer data is missing?
We identify the gap and its effect. A missing value is never made to look like confirmed input; any working assumption must be explicit and agreed.
Can you simulate solar, batteries and hybrid plants?
Yes, subject to adequate component models and parameters. The validation approach and exact scenarios are defined for the plant and the intended use of the report.
