Tutorial 1: PV modelling for EMT-simulation, Date: May 9, 2019

Synopsis

PV modelling for EMT-simulation

The amount on renewable energies in electrical grids is constantly growing and, with it, the need to improve the simulation tools and models used to study

their integrations. More and more system operators are now requiring very advanced EMT models for new wind or solar projects. This tutorial will focus on Photovoltaic (PV) parks.

The objective is to understand why it is important to simulate PVs with time-domain software and to learn how to model them for EMT simulations.  The focus will be brought on:

  • PV cell modelling with manufacturer datasheet
  • Converter models: average-value versus detailed models
  • Power Plant Controller (PPC) and inverter control
  • Maximum Power Point Tracking (MPPT)
  • Protections
  • Harmonics

Generic models will be presented with a discussion on practical aspects. This tutorial will also address PV initialization challenges and propose automatic initialization methods.

LVRT simulations will be presented to verify the compliance of models with grid codes. A case of temporary overvoltage (TOV) will be demonstrated

Presenter:  Henry Gras. M.A.Sc.

Henry Gras received the M.A.Sc. degree from Polytechnique Montréal, Canada in 2014. Since then, he has been working as a research associate at Polytechnique Montréal where he is engaged in research and development activities related to time-domain simulation of power systems.  He is also currently working with the EMTP Alliance as a developer of the ElectroMagnetic Transient Program (EMTP).
