Finally, future research prospects in long-term low-cost energy storage, power/energy balancing, and stability control, are emphasized. 1. Introduction A microgrid is a power grid that gathers distributed renewable energy sources and promotes local consumption of renewable energies .
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. In this article, a literature review is made on microgrid technology.
A 2018 World Energy Council report showed that energy storage capacity doubled between 2017 and 2018, reaching 8 GWh. The current projection is that there will be 230 GW of energy storage plants installed by 2030 [2, 3, 4, 5]. Microgrids are a means of deploying a decentralized and decarbonized grid.
Microgrids are small-scale energy systems with distributed energy resources, such as generators and storage systems, and controllable loads forming an electrical entity within defined electrical limits. These systems can be deployed in either low voltage or high voltage and can operate independently of the main grid if necessary .
Similar technical challenges were explored by the European Union MICROGRIDS project such as energy management, safe islanding and re-connection practices, protection equipment, control strategies under islanded and connected scenarios, and communications protocols .
deployment of microgrids. Microgrids offer greater opportunities for mitigate the energy demand reliably and affordably. However, there are still challenging. Nevertheless, the ene rgy storage system is proposed as a promising solution to overcome the aforementioned challenges. 1. Introduction power grid.

1 Introduction. Given the fact that the environmental pollution is increasingly serious and the fossil fuels are becoming depleted, distributed energy resources (DERs) such as wind power, solar power, and so on are paid great attention to and employed extensively [1, 2].Microgrid is the concept proposed to deal with the penetration of a certain amount of DERs.

The concept of microgrid is evolving by leaps and bounds and assumes various forms depending on location and local requirements (Wouters 2015, 23).At the same time, the definition of microgrid is not based on a minimum or maximum size of a microgrid system but rather on function (Soshinskaya et al. 2014, 661). A generic definition treats microgrid as a …
Thus, the performance of microgrid, which depends on the function of these resources, is also changed. 96, 97 Microgrid can improve the stability, reliability, quality, and security of the conventional distribution systems, that it is the reliable and more useful technique to produce electric power and reduce the use of the nonrenewable energy source. 98, 99 Nevertheless, …
Systematic research and development programs [10], [11] began with the Consortium for Electric Reliability Technology Solutions (CERTS) effort in the United States [12] and the MICROGRIDS project in Europe [13].Formed in 1999 [14], CERTS has been recognized as the origin of the modern grid-connected microgrid concept [15] envisioned a microgrid that …

Recently, DC microgrids and distribution systems are also taken into consideration due to the widespread of DC sources and loads . Therefore, future microgrids are predicted to be hybrid AC/DC microgrids, due to their capability to utilise benefits of both AC and DC microgrids. Due to above-mentioned merits, a hybrid AC/DC microgrid is ...
Generally, microgrids integrate local power generation from renewable sources like solar, wind, etc., but considering the intermittent nature of generation from renewable sources, there is a need for energy storage systems which are discussed in [2, 3]. Then at the heart of microgrid is the controller which monitors overall parameters.
Microgrids are relatively small-scale electricity distribution systems utilizing local resources. They may include energy storage as well as heat and cool distribution units. …
