The broader impact/commercial potential of this project is to enable vast deployment of energy storage to increase installation of renewable energy for reduced pollution and greenhouse gases, to improve energy security, and to improve energy efficiency and safety. The project will realize a dramatic reduction in cost and size of Energy Storage Systems (ESS) that will allow penetration of ESS into markets served by fossil fuels. One key market is grid ancillary services which includes Frequency Regulation (FR) that regulates grid frequency and stability. With the potential of this project, the FR market for battery based ESS is expected to grow from $100M/yr to over $4B/yr. This project has the societal benefits of replacing fossil fuel based ?peaker? plants that are commonly used to perform FR, with clean Li-ion battery based ESS. Furthermore, by providing lower cost FR capability for the grid, the project will enable grid penetration of more renewable energy, which requires additional FR capability.This Small Business Innovation Research (SBIR) Phase 1 project will develop a highly compact integrated modular inverter/energy storage system to revolutionize deployment of energy storage system for grid, micro-grid, energy efficiency, and energy reliability support. The development effort proposed here includes an advanced energy storage system consisting of an extremely compact 150kW high frequency 3-Level inverter, an integrated 48kWhr compact Li-ion battery system, proprietary battery management systems and internet communications capability. This will provide a highly integrated and scalable 150kW Energy Storage System with an integrated battery string inverter with 60% reduced system cost and 10X reduced size that open new markets for energy storage and renewable energy. The project will develop key technology innovations which work together with advanced Li-ion batteries to form a revolutionary new product. These innovations include: high frequency 3-level inverter with innovative high frequency control and output filter to achieve 10X reduction in volume; a novel topology that integrates inverters into each cell string and eliminates many components resulting in 60% system cost reduction; a modular and scalable design that is fault-tolerant and allows easy optimization for multiple system uses.

该项目更广泛的影响/商业潜力是能够大规模部署能源储存，以增加可再生能源的安装，减少污染和温室气体，提高能源安全，并提高能源效率和安全性。该项目将大幅降低储能系统（ESS）的成本和规模，使ESS能够渗透到化石燃料服务的市场。一个关键的市场是电网辅助服务，其中包括调节电网频率和稳定性的频率调节（FR）。凭借该项目的潜力，基于电池的ESS的FR市场预计将从1亿美元/年增长到超过40亿美元/年。该项目具有取代化石燃料的社会效益？peaker？此外，通过为电网提供更低成本的FR能力，该项目将使更多的可再生能源进入电网，这需要额外的FR能力。这个小型企业创新研究（SBIR）第一阶段项目将开发一个高度紧凑的集成模块化逆变器/能源存储系统，以彻底改变能源存储系统的部署，为电网、微电网、能源效率和能源可靠性提供支持。这里提出的开发工作包括一个先进的储能系统，包括一个非常紧凑的150 kW高频3级逆变器，一个集成的48 kWhr紧凑型锂离子电池系统，专有的电池管理系统和互联网通信能力。这将提供一个高度集成和可扩展的150 kW储能系统，该系统具有集成的电池组逆变器，系统成本降低60%，尺寸缩小10倍，为储能和可再生能源开辟了新市场。 该项目将开发关键技术创新，与先进的锂离子电池一起形成革命性的新产品。这些创新包括：高频3电平逆变器，具有创新的高频控制和输出滤波器，可实现10倍的体积缩小;新颖的拓扑结构，将逆变器集成到每个单元串中，并消除了许多组件，从而使系统成本降低60%;模块化和可扩展的设计，具有容错能力，可轻松优化多个系统用途。
