Course Catalogue.

After participating in this course, you will be able to:

• Identify potential grid interconnection issues for DG systems
• Minimize the impact of DG interconnections
• Effectively protect DG systems and prevent system islanding
• Interpret interconnection requirements for DG systems

Description

Distributed generation (DG) is becoming common since the introduction of alternative generation methods connected to the grid. As consumers and generators seek to make more installations, there will be increased impact levels to the grid stability and DG system protection. There is then a need for a proper understanding of how to integrate DG systems and mitigate adverse impacts on others.

In this course, you will enhance your understanding of the challenges and impacts of DG systems, and be provided with a base knowledge of the solutions available to implement DG with the grid. An overview of the core requirements for DG interconnection to the grid, as outlined by the IEEE and Hydro One, will be provided.
