Flexibility services based on Connected and interoperable Hybrid Energy Storage System

可再生能源（RES）的大规模集成引入了一种新的运行模式。可再生能源的特点是不确定性和波动性。此外，输电和配电馈线的过载变得更加频繁。因此，可再生能源发电的削减有所增加，与可再生能源高份额的目标相矛盾。应对这些挑战的一个有价值的解决方案是从灵活的资源和负载中引入灵活性。在此背景下，FlexCHESS项目提出了基于数字孪生概念、虚拟储能系统（VESS）和分布式账本技术（DLT）的尖端解决方案，以彻底改变现有的实践。基于互联混合储能系统（CHESS）的聚合，FlexCHESS通过保证配电和输电网络层面的各种辅助服务，提高电网稳定性，同时提高其设施的盈利能力。FlexCHESS还将确保拟议解决方案的最高水平的互操作性，并通过解锁有意义的信息和共同创造新的商业机会来提高欧洲中小企业和初创企业的创新能力和竞争力。这将通过适当促进开放式创新并使智能技术成为智能业务的资产来实现。为了验证和评估所提出的解决方案，计划在不同的欧洲国家进行五个具有不同资产的试点演示。不同资源的聚合和优化将扩展到不仅考虑电能存储系统（ESS），而且考虑多个ESS。因此，FlexCHESS项目将定义不同的场景，以评估CHESS的性能和灵活性。FlexCHESS项目联盟聚集了3所大学，2家大公司，3DSO，4家中小企业和2个NGO.no项目摘要。

The large scale integration of renewable energy sources (RES) has introduced a new operating paradigm. Renewable energy sources are characterized by uncertainty and volatility. Moreover, overloading of transmission and distribution feeders have become more frequent. The curtailment of renewable power generation has thus increased, contradicting the goals for high shares of RES. A valuable solution to these challenges is the introduction of flexibility from flexible resources and loads. In this context, FlexCHESS project proposes cutting-edge solutions based on digital twin concept, Virtual energy storage systems (VESS) and Distributed Ledger Technology (DLT) to revolutionize the existing practices. Based on the aggregation of Connected Hybrid Energy Storage System (CHESS), FlexCHESS improves the grid stability while increasing the profitability of its installations by guaranteeing various ancillary services at the distribution and transmission network levels. FlexCHESS will also ensure the highest level of interoperability of the proposed solutions and enhance the innovation capacity and competitiveness of SMEs and Startups in Europe by unlocking access to meaningful information and co-creating new business opportunities. This will be achieved by the appropriate promoting of open innovation and making smart technologies an asset for intelligent business. In order to validate and evaluate the proposed solutions, five pilot sites demonstrations with diverse assets in different European countries are planned. The aggregation and optimization of different resources will be extended to take into account not only electrical energy storage systems (ESS), but also multi-ESSs. Thus, FlexCHESS project will define different scenarios allowing to evaluate the performances and flexibility capability of CHESS.
