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.

拟议与北方变压器公司的合作研究项目是开发一种新型、高度紧凑的光伏（PV）最大功率点跟踪（MPPT）电源接口，采用有源功率补偿技术，用于大型光伏能源转换系统。 具体来说，所提出的中压光伏电源接口将能够同时提供精确的大规模光伏MPPT功能，并向具有故障穿越功能的中压电网注入有功或无功功率。 所提出的光伏电源接口可以与升压中压（MV）功率转换级集成，形成单级MV PV升压功率转换系统。 该技术的新颖性在于光伏能源MPPT功率接口的独特电路结构以及所提出的有源功率补偿方案的多功能控制特征。 该技术的成功开发将带来高度紧凑的单级光伏电力转换过程，该过程在整个工作范围内实现非常高的电力效率，同时为输入端不同太阳辐射的电网提供电力补偿。 Northern Transformer 的研究主管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。 Northern Transformer 热衷于开发拟议的光伏发电解决方案，以取代传统的中压底座安装变压器，将可再生能源连接到电网，因为这将显着降低成本和尺寸，并提高可靠性。 研究成果将提高更高效、更清洁的可再生能源系统的承受能力和增长。这种增长将导致温室气体大幅减少、环境改善、电力负担得起以及加拿大人的健康状况改善。
