When was the concept of microgrid proposed

A microgrid, regarded as one of the cornerstones of the future smart grid, uses distributed generations and information technology to create a widely distributed automated energy delivery network. This paper presents a review of the microgrid concept, classification and control strategies.

A complete concept of micro-grid was proposed by American Association of Reliability Technology Solutions (CERTS). It was defined that microgrid is a system composed of microsources and loads, which can provide both electricity and thermal energy.

In 2004, China began to carry out research on the concept of microgrids as proposed by the United States. This research has been based on the connection of distributed generation to large electrical grids via AC (alternating current) microgrids and the impacts of microgrids on large grids.

From the 1920s through the 1970s, the increased reliability afforded by connecting multiple generating units to diverse loads, decreased construction costs per kilowatt (kW), and ability to draw power from distant large generating resources like hydropower drove the development of the grid we see today [2], [3].

Microgrid is an important and necessary component of smart grid development. It is a small-scale power system with distributed energy resources. To realize the distributed generation potential, adopting a system where the associated loads and generation are considered as a subsystem or a microgrid is essential.

6 FAQs about [When was the concept of microgrid proposed ]

Why is microgrid important in Smart Grid development?

What is a microgrid?

The term “microgrid” refers to the concept of a small number of DERs connected to a single power subsystem. DERs include both renewable and /or conventional resources . The electric grid is no longer a one-way system from the 20th-century . A constellation of distributed energy technologies is paving the way for MGs , , .

What is microgrid development research?

Another critical area of microgrid development research is using artificial intelligence (AI) and machine learning (ML) techniques to optimize the operation of microgrid systems. AI and ML can analyze large amounts of energy consumption and production data and identify patterns and trends that can help optimize microgrid systems’ operation.

What role will microgrids play in the future power grid?

As an important part of the smart grid of the future, microgrids will play an important role in the future power grid by taking advantage of its strengths such as accommodation of diversification of energy forms, flexibility of grid connection interfaces, customization of power quality, and bi-directional energy information flow.

Where are micro-grids developed?

Nowadays, both pilot and commercialized micro-grids have been developed in many countries and areas in the world. America first proposed the completed concept of micro-grid . The CERTS is main research organization of American micro-grid and supported from US Department of Energy and California Energy Commission.

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.
