The proposed collaborative research project with Northern Transformer Corporation is to develop a new, highly compact photovoltaic (PV) maximum power point tracking (MPPT) power interface with active power compensation technology for use in large-scale PV energy conversion systems. To be specific, the proposed MV PV power interface will be capable of simultaneously providing accurate large-scale PV MPPT function and injecting active or reactive power to the MV grid with fault-ride-through feature. The proposed PV power interface can be integrated with the step-up medium voltage (MV) power conversion stage to form a single-stage MV PV step-up power conversion system. The novelty of the proposed technology lies in the unique circuit structure of the PV energy MPPT power interface and the multi-functional control features of the proposed active power compensation scheme. Successful development of this technology will result in a highly compact single-stage PV power conversion process that achieves very high power efficiency for the entire operating range while at the same time, provides power compensation for the grid with varying solar irradiation at the input. The Head of Research from Northern Transformer will provide technical expertise on addressing these design challenges to help the team to achieve the project goal. Northern Transformer is keen to develop the proposed PV power solution to replace the conventional MV pad mount transformer for connecting the renewable energy source to the grid, as it will result in a significant reduction of cost and size as well as increased reliability. 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.

与北方Transformer公司的拟议合作研究项目是开发一种新的、高度紧凑的光伏（PV）最大功率点跟踪（MPPT）电源接口，该接口采用有源功率补偿技术，用于大规模光伏能量转换系统。 具体而言，建议的中压光伏电源接口将能够同时提供准确的大规模光伏MPPT功能和注入有功或无功功率到中压电网故障穿越功能。 所提出的PV功率接口可以与升压中压（MV）功率转换级集成以形成单级MV PV升压功率转换系统。 所提出的技术的新奇在于独特的电路结构的光伏能源MPPT电源接口和多功能的控制功能的建议有功功率补偿方案。 该技术的成功开发将导致高度紧凑的单级光伏功率转换过程，该过程在整个操作范围内实现非常高的功率效率，同时在输入处具有变化的太阳辐射的情况下为电网提供功率补偿。 来自北方Transformer的研究负责人将提供解决这些设计挑战的技术专业知识，以帮助团队实现项目目标。 北方Transformer热衷于开发拟议的光伏发电解决方案，以取代传统的MV垫安装式Transformer，将可再生能源连接到电网，因为它将导致成本和尺寸的显着降低以及可靠性的提高。 研究成果将提高更高效、更清洁的可再生能源系统的可负担性和增长。这种增长将导致温室气体的大幅减少，改善环境，负担得起的电力和加拿大人的健康状况。
