State Grid Micro-Course Competition

Where can electrical utilities test microgrid concepts?

Electrical utilities have begun testing microgrid concepts in laboratory-type settings. One example is Duke Energy, which maintains two test microgrid facilities: one in Gaston County, North Carolina , and one in Charlotte, North Carolina .

How much does a microgrid cost?

Microgrids are complex systems that require specialized skills to operate and maintain. Microgrids include controls and communication systems that contain cybersecurity risks. A 2018 study conducted by the National Renewable Energy Laboratory found that microgrids in the Continental U.S. cost an average of $2 million-$5 million per megawatt.

How can we overcome the challenges of Microgrid technology?

To overcome this challenge, it will be important for governments, businesses, and investors to invest in microgrid technology, providing the funding and support needed for the development and implementation of microgrids. This could be in the form of grants, subsidies, or investment opportunities.

What is a microgrid and how does it work?

A microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid.2 A microgrid can operate in either grid-connected or in island mode, including entirely of-grid applications. Figure 1 shows one example of a microgrid.

What is a Certs microgrid?

The CERTS microgrid concept has been deployed in a test-bed setting , and in real-world microgrid projects , . While the initial motivation of CERTS was to improve reliability rather than to reduce greenhouse gas emissions, per se, CERTS microgrids can incorporate renewable microgeneration sources.

Why do microgrids need a sophisticated energy management system?

Microgrids require a sophisticated energy management system to ensure that energy is being used efficiently and effectively, and that the flow of energy is balanced between generation and storage. In addition, microgrids must be designed to be flexible and scalable, able to adapt to changing energy needs and requirements.
