几十年来，美国电网一直是可靠且可靠的电力分配来源。然而，由于生产脱碳、交通电气化、极端天气事件等多种因素，电力的集中生产和分配不再像以前那样可靠。

As a result, many government institutions, businesses, and communities are now turning to microgrids as a solution to keep the power on during outages. So, what exactly is a microgrid? A microgrid is an interconnected electrical system that consists of multiple generation sources and controllable loads. It can operate in parallel or independently from the utility grid and is designed to provide a reliable solution for unexpected power loss and energy management. The generation sources in a microgrid are often referred to as distributed energy resources (DERs), which are decentralized assets controlled as an integrated system.

微电网本质上是较大电网内的微型电网，它可以自主运行或与主电网“孤岛”运行，以实现最大的系统弹性。其主要目的是在公用电网停电时提供不间断且可靠的电力，确保关键操作能够不间断地继续进行。

So, how does a microgrid actually work? A microgrid coordinates various power generation assets that can either work in conjunction with a utility provider to augment their production or operate autonomously to power critical operations. These assets typically include traditional fossil fuel generators, as well as renewable sources such as wind, solar, and energy storage. The microgrid works by generating and optimizing energy usage to provide resilient, efficient, and sustainable electricity solutions.

为了使微电网的各个组件能够协调运行，需要使用智能微电网控制系统。这些控制系统可以被视为 DER 管弦乐队的指挥，确保所有资产无缝协作。

微电网的主要优势之一是其灵活性和定制性。每个微电网都可以进行定制，以满足部署它的组织的特定需求和要求。根据优先级，组织通常会优先考虑三个目标：弹性、效率和可持续性。然而，建立一个完全满足所有三个目标的微电网可能成本高昂。因此，开发人员与组织密切合作，了解他们的独特需求，并确定定制设计适当的解决方案所需的应用程序和资产。

Resilience is a major concern for many companies and residential communities. With the increasing threat of cyber-attacks and extreme weather events, access to consistent and reliable power is crucial. Many states have recognized the importance of microgrids in reducing or eliminating power loss and have invested in them as part of their disaster-response efforts. Microgrids not only help bolster critical operations but also contribute to a more resilient energy infrastructure, ensuring that communities can quickly recover from a crisis.

Efficiency is another key benefit of microgrids. Governments, corporations, and institutions can achieve financial benefits through cost avoidance and external monetization. Cost avoidance involves maximizing the use of freely produced energy from renewable sources. When energy storage is added to renewable sources, it enables the stored power to be used during times of high utility grid energy costs, reducing peak demand charges and providing utility bill savings. External monetization occurs through participation in demand response programs or selling energy services to third parties.

Lastly, microgrids play a significant role in sustainability efforts. Many organizations have established goals to reach carbon neutral operations by a given date. However, one of the challenges with renewable energy sources like solar and wind is their intermittent nature. Microgrids can utilize a combination of renewable sources and battery energy storage systems to store excess energy during times of peak generation and discharge it when renewable sources are not producing enough to meet the demand. This helps organizations achieve their decarbonization goals while providing energy cost savings and operational resiliency.
