Abstract

In order to achieve net-zero carbon emissions by introducing enormous amount of renewable energy, it is essential to secure the reserve power to improve the power quality of the grid. On the other hand, improvement of the grid resiliency is also needed in case of emergency such as outage of the grid. The energy storage system can be the solution for both of securing the reserve power and improving grid resiliency. The authors have conducted demonstration project to validate the applicability of Redox Flow (RF) battery for securing the reserve power and improving grid resiliency. The results of the demonstration validated that the RF battery makes it possible to be used as reserve power and earn revenue through energy and ancillary market transactions during normal operations, in addition to providing power to blackout areas or the areas that outages are assumed, as an independent power source, during an emergency such as natural disasters and planned outages.

示范应用氧化还原液流电池确保供需储备电力和提高电网韧性

为了通过引入大量可再生能源实现净零碳排放，必须确保储备电力，以提高电网的电能质量。另一方面，还需要提高电网的弹性，以应对电网断电等紧急情况。储能系统可以同时解决保障储备电力和提高电网弹性的问题。作者开展了一个示范项目，以验证氧化还原液流（RF）电池在确保储备电力和提高电网弹性方面的适用性。演示结果验证了氧化还原液流电池可在正常运行期间用作储备电力，并通过能源和辅助市场交易赚取收入，此外还可在自然灾害和计划停电等紧急情况下作为独立电源向停电地区或假定停电地区供电。
