modelPIwithNoVariableLimiter
PI with no variable limiter controller for WECC electrical controllers
Information
Specific PI with no variable limiter component for the WECC-based renewable energy controller models.
The modelling of such component is based, mainly, on the following reference:
- Mohammed, M., Federico, M.: "Modeling and Simulation of PI-Controllers Limiters for the Dynamic Analysis of VSC-Based Devices" [Mohammed2019],
