Next Generation Adaptive Medium Voltage Power Converters for Renewable Energy Conversion

根据《巴黎协定》，加拿大承诺到2030年将其温室气体排放量(GHG)在2005年的基础上减少30%。为了实现这一雄心勃勃的目标，加拿大正在采取行动，通过优先发展清洁和负担得起的可再生能源发电，如风能和光伏能源，在未来10年内完全淘汰燃煤发电。为了促进大规模的可再生能源转换为负担得起的电力，高效、可靠和经济的中压电力转换至关重要。与当前的中压交流(MVAC)电网电力体系结构相比，新兴的中压直流(MVDC)电网电力体系结构具有一些优点，例如：消除了与每个可再生发电机组相关的大占地面积的升压变压器，并在与电网解耦时需要频率同步；减少了电力传输电缆的数量；以及易于互联大容量的储能装置。该研究计划的目标是在大规模光伏或风能系统中开发一系列高能效、高性价比的新型MVDC功率变换系统。所提出的变流器是紧凑型自适应中压功率变流器系统，在整个工作范围内表现出非常高的功率效率。该计划的短期目标是：1.设计适用于大规模光伏系统的新型自适应高功率效率DC/DC升压中压功率转换器。2.设计了适用于高功率风力发电系统的新型自适应高效AC/DC三相升压中压功率变流器。3.设计了适用于MVDC电网储能的新型自适应高功率效率DC/DC双向功率转换器。该计划的长期目标是培训HQP进行可再生能源转换的电力电子技术；在加拿大的温室气体减排计划中发挥积极作用；并与各行业合作，进一步将设计的电力技术开发成商业产品，用于可再生能源部门。拟议研究计划的成果将为可再生能源应用开发创新和高效的功率转换器解决方案。研究成果将提高更高效、更清洁的可再生能源系统的负担能力和增长能力。这样的增长将导致温室气体显著减少，环境改善，负担得起的电力和加拿大人更好的健康。公平、多样性和包容性也是约克大学先进电力电子可持续能源研究实验室(Pelser)培养HQP和高质量多方面研究的最重要因素。因此，该研究项目的招聘过程将继续保持一个多元化和包容性的学术团队，并培养一个积极和公平的研究环境。

Canada is committed to reducing its greenhouse gas emissions (GHG) by 30% below 2005 levels by 2030 under the Paris Agreement. To meet this aggressive target, Canada is taking action to completely phase out coal-fired electricity within the next 10 years by prioritizing the development of clean and affordable renewable power generation, such as wind and photovoltaic (PV) energy. To facilitate large scale renewable energy conversion to affordable electricity, highly power efficient, reliable and cost-effective medium voltage power conversion is vital. In comparison to current medium voltage AC (MVAC) grid power architecture, the emerging medium voltage DC (MVDC) grid power architecture offers several advantages, such as: the elimination of the large-footprint step-up transformer associated with each renewable generation unit and need of frequency synchronization when decoupling from the grid; the reduction of the number of power transmission cables; and the ease of inter-connecting high capacity energy storage. The goal of the proposed research program is to develop a wide range of highly power-efficient, cost-effective, and novel MVDC power converter systems in large-scale PV or wind energy systems. The proposed converters are compact adaptive MV power converter systems that exhibit very high power efficiency over the entire operating range. The short-term objectives of this program are to: 1. devise novel adaptive highly power efficient DC/DC step-up MV power converters for large-scale PV energy systems. 2. devise novel adaptive highly power efficient AC/DC three-phase step-up MV power converters for high power wind turbine systems. 3. devise novel adaptive highly power efficient DC/DC bi-directional power converters for energy storage in the MVDC grid network. The long-term objectives of this program are to train HQP in power electronics for renewable energy conversion; to play an active role in Canada's GHG reduction plan; and to collaborate with industries to further develop the devised power technology into commercial products for use in the renewable energy sector. The outcome of the proposed research program will develop innovative and highly efficient power converter solutions for renewable energy application. The research outcomes will increase the affordability and growth of more efficient and clean renewable energy systems. Such growth will lead to significant reductions in GHG, improved environment, affordable electricity and better health of Canadians. Equity, diversity and inclusion is also of the utmost importance at the Advanced Power Electronics Lab for Sustainable Energy Research (PELSER) at York University for fostering HQP and for high quality multifaceted research. As such, the recruitment process for this research program will continue to maintain a diverse and inclusive academic team and to foster a positive and equitable research environment.
