Rte's challenge : Hybrid AC/DC network

Studies on a grid including large number of HVDC links

New grid, new challenges, new problems… To be sure that equipment and grid will operate properly To investigate failures or incorrect operation of equipment From planning, to commissioning and maintenance for over several decades Type of studies

DC and AC dynamic performance studies : performance of numerous study cases to verify the transient and dynamic behavior as well as DC protection Harmonic studies Interactions of various electrical installations (e.g. between 2 HVDC systems)

Rationale for Real time simulation

Simulation tools - issues to be addressed (1/3) Validation of models used in studies

• Behavior of HVDC and FACTS is mainly driven by a proprietary control system algorithm : model = black box or simple representation based on block diagrams

• Black box models (EMT and TS tools) do not use the same numerical solution than the real controller

Real system EMT Model



Simulation tools - issues to be addressed (2/3) Maintenance of models

• Models are delivered during commissioning based on an operating system and specific version of a simulation tool how to keep a model running 20 years

after commissioning… • Update models depending on equipment parameters changes (change in regulation loops,…) during several decades.

10 years after commissioning… Real system

EMT Model



Simulation tools - issues to be addressed (3/3) Simulation times

• Detailed and accurate model can lead to slow simulations. Fast simulations to study a large number of configurations and deliver results in a short period of time • Fast and detailed models for training

Rte's requirements for real time simulator

Flexible and powerful simulator

• Simulation tool suitable for studying complex and large systems (several thousand of devices) • Automatic partitioning feature to run large system in real time • Offline simulations shall be conducted with the RT tool on standard PC to prepare the real-time simulations

Possibility to develop evolutions of the RT tool

• Interface to develop user coded models (C code, DLL…) • Access to the code for a better control of study quality

8


Compatibility with the offline simulation tool EMTP-RV

• Automatic data export feature from EMTP-RV • A common GUI would be the best • Full compatibility with Matlab/Simulink for control system models

use same control system models in EMTP-RV and RT simulator
