Intelligent Grid-scale Energy Storage System (INGRESS)

Brill Power正在进行一项可行性研究，以开发其新的电池管理系统(BMS)技术，应用于由Narec分布式能源(Narec DE)部署的49.9兆瓦电网规模的太阳能加储能系统(ESS)。太阳能加存储将清洁、可再生但可变的太阳能发电与一种存储能源的手段相结合，有助于实现供需匹配。这可以帮助避免网络加固，还可以贡献频率响应等网格服务。将太阳能光伏发电与电池存储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、许可和开发商管理费用，系统成本降低了约8%(NREL，2019年)。此外，通过对可变太阳能的最佳利用来增加收入。将太阳能光伏与储能相结合的问题是，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，现有的电池技术对其使用情况非常敏感，使用越多，其退化越快，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起大规模电池火灾中的一起，发现过度使用电池导致了极端的磨损，这是火灾的根本原因(IHS Markit，2020)。Brill Power开发了一种新型BMS，可以显著降低电池退化的速度。这使运营商能够在不降低项目寿命或安全性的情况下获得更多收入流。此外，带有Brill Power BMS的电池可以直接连接到太阳能光伏阵列，而不需要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，开源的BMS使网格服务的需求能够更容易地满足，并随着服务的变化而随着时间的推移进行修改，从而使电池系统面向未来。在第二阶段结束时，利益相关者将能够在Narec DE的场地上为49.9兆瓦的能量存储系统商业化推出这项技术，该系统将与一个太阳能光伏发电场位于同一地点。

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.
