建设微电网需要几个阶段，从指定储能组件的详细要求到设计太阳能发电场和飞轮。
Defining Microgrid Design Requirements and Energy Storage Needs
最初的一些步骤是了解各种功能和组件的详细要求，如结合屋顶太阳能发电场的储能和穿越式供电。接下来，我们确定了技术部分：
- 太阳能发电场的双面电池板
- 用于储能的钒氧化还原液流电池
- 飞轮提供穿越动力
These technologies would ultimately interface with G&W Electric’s medium-voltage distribution components, including switchgear and protective devices that help support safe and reliable operation.
We went through engineering studies for the installation locations to ensure they could sustain the weights and properly integrate with G&W Electric’s MV equipment. Also, we undertook extensive design research for the flywheel and energy storage foundations. They weigh over 50 tons and 110 tons, respectively, and must withstand the 25-year life span.
Integrating Microgrid Components for a Reliable Distribution System
We designed a medium voltage loop employing magnetically operated switchgear, miles of medium voltage cable, arrestors, and rubber goods (such as elbows).
In addition, we needed a connection between the controls. Given the localized area of the system, the most suitable communication medium is fiber optic cable. This communication ties into G&W Electric’s automation hardware, which coordinates switching operations and enhances system responsiveness. We went through tunneling and placed the conduits underground before running the cables (medium-voltage and fiber).
Commissioning Components and Validating System Reliability
一旦组件成为一个系统，就需要对每个组件进行调试，并进行系统测试。这一过程需要多方合作，包括当地公用事业部门、负责安装的承包商、组件供应商，当然还有 G&W Electric 的自动化工程团队及其维护团队。
Frequently Asked Questions
What role do microgrid components play in improving system reliability?
Microgrid components, such as medium-voltage switchgear, protection equipment, control systems, and energy storage systems, work together to maintain reliable power flow and support distributed energy resources without requiring a full turnkey microgrid solution.
How does energy storage technology support microgrid design?
Energy storage technology, including battery energy storage systems and flywheel ride-through solutions, helps stabilize energy supply and enables smoother transitions between distributed energy resources. These systems must work seamlessly with medium-voltage distribution equipment to ensure safe operation.
Does G&W Electric provide complete microgrid design or installation services?
No. G&W Electric does not provide full microgrid design or installation. Instead, the company supplies critical medium-voltage components, control systems, and protective equipment that support microgrid designers, utilities, and engineers developing smart power infrastructure projects.
How do energy storage systems help reduce energy costs in microgrid environments?
Energy storage systems can store excess energy from distributed sources like solar panels and release it during peak demand, helping reduce energy costs. G&W Electric’s distribution equipment supports the safe and efficient integration of these systems within the larger electrical network.
How do control systems enhance the performance of distributed energy resources?
Control systems coordinate switching operations, manage distributed energy resources, and maintain stable energy supply. G&W Electric’s automation and control solutions are designed to improve system responsiveness without implying full microgrid control implementation services.
How does microgrid energy storage support the components used in this project?
Microgrid energy storage helps maintain stable operation by supporting the solar panels, flywheel system, and other distributed resources used in this project. While G&W Electric does not provide the energy storage assets themselves, our medium-voltage switchgear, protection devices, and automation controls help these technologies operate safely within the overall microgrid configuration.
