What is a microgrid?

The DOE defines a microgrid as a group of interconnected loads and distributed energy resources (DERs) within clearly defined electrical boundaries that acts as a single controllable entity with respect to the power grid.

What is microgrid planning & design?

This practical book is a compilation of collaborative research results drawn from a community of experts in 8 different universities over a 6-year period. Microgrid Planning and Design contains a review of microgrid benchmarks for the electric power system and covers the mathematical modeling that can be used during the microgrid design processes.

What is a microgrid report?

This report provides (1) an overview of the microgrid planning, assessment, and design process for DoD installations and (2) is a resource for energy managers, policymakers, contractors, and other stakeholders involved in microgrid projects.

What drives microgrid development?

Resilience, efficiency, sustainability, flexibility, security, and reliability are key drivers for microgrid developments. These factors motivate the need for integrated models and tools for microgrid planning, design, and operations at higher and higher levels of complexity.

How much construction is required for a microgrid project?

The level of construction for a microgrid project will vary considerably depending on the amount of new infrastructure required. If a lot of new infrastructure such as generation equipment, communications lines, and electrical equipment is required, the construction process can be quite long and involved.

How to resynchronize a microgrid to the main grid?

Two different control loops have been implemented to resynchronize the microgrid to the main grid. The first one is based on an active method which forces the master unit to adjust its active and reactive power outputs to rapidly adapt the overall system frequency and voltage magnitude to the reference signal.
