GU306: 100% Inverter-based Microgrids: Design, Protection, and Control
In today’s evolving distribution systems, microgrids play a vital role in enhancing reliability and resiliency, enabling seamless integration of distributed energy resources (DERs), and improving power quality for end users. Central to these advancements is grid-forming inverter technology, which serves as the foundational enabler for modern, fully inverter-based microgrids.
While the goal is to streamline microgrid design, the technical, financial, and regulatory complexities require a careful, phased approach tailored to each project’s unique requirements. This course begins with an overview of microgrid types, business models, applications, and critical design considerations, with a particular focus on inverter-based microgrid architectures.
The core emphasis is on the operation, control, and protection of microgrids powered predominantly by inverters, highlighting grid-forming inverters as the primary energy sources within these advanced systems.
Participants will explore the following key topics:
- Overview of microgrid types, business models, and fundamental building blocks
- Performance requirements and relevant industry standards for inverter-based microgrids
