NEXT GENERATION MODULAR SIC-BASED ADVANCED POWER ELECTRONICS CONVERTERS FOR ENHANCED RENEWABLES INTEGRATION INTO THE GRID

SiC4GRID是一个为期42个月的项目，它聚集了基于碳化硅的转换器完整价值链中的合作伙伴，共同努力解决目前阻碍这些技术进入市场的障碍。因此，SiC4GRID的目标是一种优化的基于SIC的集成技术，由硬件、软件和物联网三方面的创新组成。事实上，为了优化技术经济和环境支柱，该联盟将设计、生产、测试和验证一种集成产品，该产品由尺寸较小30%的节能碳化硅功率模块组成，与最先进的技术竞争，并结合适应的优化自我修复能源管理系统(EMS)。这款EMS扩大了强大的系统级物联网架构的优势，并采用了数字孪生和优化算法等数字工具。在整个项目中，转炉制造过程的所有步骤的循环性和生态设计将是目标，重点是资源优化和碳排放减少。测试阶段将作为物理测试台上的集成模块化转换器进行，以及以数字方式增加相关应用和实际情况的多样性。因此，对于数字模拟，将选择三个用例来增加经过验证的参数和应用范围，包括MMC和SST转换器、陆上/海上风能和光伏应用以及存储潜力。总体而言，该项目通过降低成本(与硅转换器相比降低了30%的成本)、尺寸(减少15%的尺寸)、使用寿命(30年以上)和对环境的影响(减少30%的资源消耗和50%的二氧化碳排放)，促进了该技术的市场准备程度。因此，从长远来看，SiC4GRID还将帮助可再生能源整合能源电网，并将欧洲的领先地位带入变流器技术供应商的前沿。

SiC4GRID is a 42-months project gathering partners from the complete value chain of SiC-based converters collaborating to tackle current obstacles to the technologies' market uptake. SiC4GRID thus aims for an optimised integrated SiC-based technology composed of three-fold innovations in terms of hardware, software and IoT. Indeed, to optimise both techno-economic and environmental pillars, the consortium will design, produce, test and validate an integrated product composed of a 30% smaller size energy-efficient SiC-based power module competitive with state-of-the-art technology and coupled with an adapted optimised self-healing energy management system (EMS). This EMS amplifies the benefits of a strong system-level IoT architecture and adapted digital tools such as digital twin and optimisation algorithms. Throughout the project, the circularity and eco-design of all steps of the converter manufacturing process will be targeted with a strong emphasis on resource optimisation and carbon emission reduction. The testing phase will be done both as an integrated modular converter on a physical test bench, as well as digitally to increase the variety of relevant applications and real condition scenario. For the digital simulations, three use cases will therefore be chosen to increase the validated parameters and scope of applications, including MMC and SST converters, onshore/offshore wind and PV applications, as well as the potential for storage. Overall, the project contributes to advancing the market readiness of the technology by lowering its cost (30% cost reduction compared to silicon converters), its size (15% size reduction), its lifetime (30+ years) and its environmental impact (30% resource consumption reduction and 50% CO2 emission reduction). In the longer-term, SiC4GRID will thus also help renewable energies integrate the energy grid and bring European leadership to the forefront of converter technology providers.
