SBIR Phase I: Proof of Concept for a Manufacturable, Cost-effective, and Highly Efficient Solid State Transformer, Enabling Grid Modernization

这个小企业创新研究（SBIR）第一阶段项目展示了固态变压器（SST）的概念证明，该变压器在商业上是可行的，最终可以满足电力公用事业的要求：高效，具有成本竞争力，在特定的市场窗口内可制造，并且可扩展到高功率和高电压。虽然在SST研究领域已经有了早期的工作，但目前最先进的设计是基于组件。目前还没有商业化，限制了以合理的成本进行商业化和生产的能力。GridBridge将引入革命性的电路拓扑和独特的商用设备，以实现项目目标。该项目促进了成本效益和电力效率的解决方案，这将向市场证明SST的可行性，并最终实现互补电网技术。该项目的更广泛的影响/商业潜力是将基础研究成功转化为商业上可行和客户期望的产品：固态变压器或SST。具体到提出的革命性SST电路拓扑，概念验证是许多应用的实现技术：电动汽车充电器，储能设备和可再生能源集成。因此，第一阶段的结果值得提交给IEEE的各个部门，包括能源转换大会和博览会。该项目还将预测SST市场的引入，因此结果将通过现有的公用事业合作伙伴关系、行业白皮书和会议报告进行传播。商业上可行的SST的社会效益是巨大的，因为它是真正协调现代电网所需的阶梯式变化：发送或接收信号，做出决策，调节功率流，并轻松适应绿色技术。作为今天的直接替代品？由于该配电变压器的设计已有100年的历史，SST最终将取代大量已安装的设备和每年购买的增量设备。在电力效率方面的节省可以以数万亿美元计算。

This Small Business Innovation Research (SBIR) Phase I project demonstrates a proof of concept for a solid state transformer (SST) that is commercially feasible and can ultimately meet electric utility requirements: highly efficient, cost-competitive, manufacturable within a specific market window, and scalable both to high power and high voltage. Although there has been early work in the area of SST research, current state of the art designs are based on components that aren?t yet commercially available, limiting the ability to commercialize and manufacture at a reasonable cost. GridBridge will introduce revolutionary circuit topology and uniquely incorporate commercially available devices in order to achieve the project goals. This project facilitates a cost-effective and electrically-efficient solution, which will prove SST feasibility to the market and ultimately enable complementary grid technology. The broader impact/commercial potential of this project is the successful transformation of fundamental research into a commercially feasible and customer-desirable product: the solid state transformer, or SST. Specific to the proposed revolutionary SST circuit topology, the proof of concept is enabling technology for numerous applications: electric vehicle chargers, energy storage devices, and renewable integration. Phase I results are therefore worthy of paper submissions to various IEEE divisions, including Energy Conversion Congress and Exposition. This project will also predict an SST market introduction and the results will therefore be disseminated through pre-existing utility partnerships, via industry white-papers, and through conference presentations. The societal benefit of a commercially feasible SST is colossal, as it is the step-function change required to truly orchestrate a modern grid: sending or receiving signals, making decisions, regulating power flow, and easily accommodating green technology. As a direct replacement to today?s 100-year-old-design of the distribution transformer, the SST will eventually replace numerous installed units and an incremental number purchased annually. Savings in electrical efficiency can be calculated in the trillions of dollars.
