Description
Distributed generation (DG) is increasingly utilized as alternative energy sources, like solar and wind, become more accessible and integrated into existing power grids. Understanding the potential effects on grid stability and system protection as these installations grow is essential for maintaining seamless operations. Addressing challenges such as voltage control, fault behaviour, and reactive power compensation is critical for those responsible for managing or designing DG systems.

Participants will explore the intricacies of DG, gaining a deep understanding of its operational impact, protection requirements, and how it differs from traditional generation methods. You will also learn about the essential considerations for grid interconnections, including power flow, system monitoring, and reactive power management. Insights into regulatory standards, such as those from Hydro One and IEEE, will equip you with the knowledge to ensure compliance while optimizing system performance.

This course is designed to equip participants with the foundational and advanced knowledge necessary to manage DG systems. By covering topics such as protection strategies, fault management, and interconnection requirements, you will be able to implement solutions that enhance grid stability and effectively support distributed energy initiatives.

Who Should Attend
This course is designed for professionals involved in designing, managing, and operating electrical systems with distributed generation components.

It will benefit electrical engineers, design engineers, project managers, and power quality specialists. Maintenance managers and consultants responsible for ensuring grid stability and electronics and control personnel working with DG systems will gain actionable insights. The course is also highly relevant for technologists, traffic signal designers and operators, and other professionals working with grid-connected generation systems.

Additional audiences may include renewable energy developers, utility company engineers, and policymakers involved in implementing and regulating distributed generation technologies.
