Brill Power is conducting a feasibility study for developing its novel Battery Management System (BMS) technology for application in a 49.9MW grid-scale solar plus Energy Storage System (ESS) deployed by Narec Distributed Energy (Narec DE). Solar plus storage combines clean, renewable, but variable solar energy generation with a means to store that energy and help to match supply with demand. This can assist in the avoidance of network reinforcement and can also contribute grid services such as frequency response. Co-locating solar PV generation with battery storage is the most effective and profitable way of deploying these two technologies (US Department of Energy, 2019). System costs are reduced by ~8% (NREL, 2019) by sharing hardware components, a grid connection, land use, site preparation, permitting and developer overhead. In addition, revenues are increased by optimal utilisation of variable solar energy. The problem with combining solar PV with energy storage is that lithium-ion batteries are expensive, and to create a viable business case the battery needs to be able to tap into multiple revenue streams of grid services. However, existing battery technologies are very sensitive to their use cases and the more they are utilized, the faster they degrade, the shorter their life and the greater the safety risks. This was confirmed recently by DNV-GL, who have investigated one of 28 large-scale battery fires in South Korea and found that intensive use of the batteries led to extreme wear-and-tear, which was an underlying cause of the fire (IHS Markit, 2020). Brill Power has developed a new type of BMS, which can significantly reduce the rate of battery degradation. This enables the operator to access more revenue streams without reducing the project lifetime or safety. In addition, a battery with Brill Power BMS can be directly connected to a solar PV array without the need for DC/DC converters or charge controllers, which reduces system cost and complexity. Finally, the open source BMS enables the requirements for grid services to be more readily met and modified with time as services change, future-proofing the battery system. At the end of phase 2, the stakeholders will be in the position to commercially roll out this technology for a 49.9MW energy storage system on Narec DE's site, which will be co-located with a solar PV farm.

Brill Power正在进行一项可行性研究，以开发其新型电池管理系统（BMS）技术，应用于Narec分布式能源（Narec DE）部署的49.9MW电网规模太阳能+储能系统（ESS）。太阳能+储能将清洁、可再生但可变的太阳能发电与储存能源的手段相结合，有助于满足供需。这可以帮助避免网络加固，也可以有助于电网服务，如频率响应。将太阳能光伏发电与电池储能放在一起是部署这两种技术的最有效和最有利可图的方式（美国能源部，2019年）。通过共享硬件组件，电网连接，土地使用，场地准备，许可和开发人员开销，系统成本降低了约8%（NREL，2019）。此外，通过优化利用可变太阳能来增加收入。将太阳能光伏与储能相结合的问题在于，锂离子电池价格昂贵，为了创造一个可行的商业案例，电池需要能够利用电网服务的多个收入来源。然而，现有的电池技术对它们的使用情况非常敏感，它们被利用得越多，它们降解得越快，寿命越短，安全风险越大。DNV-GL最近证实了这一点，他们调查了韩国28起大型电池火灾中的一起，发现电池的密集使用导致了极端磨损，这是火灾的根本原因（IHS Markit，2020）。Brill Power开发了一种新型的BMS，可以显著降低电池退化的速度。这使运营商能够获得更多的收入来源，而不会减少项目的生命周期或安全性。此外，带有Brill Power BMS的电池可以直接连接到太阳能光伏阵列，而无需DC/DC转换器或充电控制器，从而降低了系统成本和复杂性。最后，开源BMS使网格服务的要求能够随着服务的变化而更容易满足和修改，从而使电池系统能够适应未来。在第二阶段结束时，利益相关者将能够在Narec DE的场地上商业化地推出这项技术，该场地将与太阳能光伏发电场位于同一地点。
