Unprecedented expansion of native direct current (DC) powered equipment (computers, telecoms, data centers, consumer electronics) has increased global electricity consumption by 27% over the past decade. In US/Canada, over 800 TWh of DC energy is consumed every year, producing an associated 550 tons of harmful carbon emissions. DC electricity usage is projected to increase even further with the addition of 20 million DC-powered electric vehicles (EV) by 2020, putting a significant burden on a century-old power infrastructure. Since power utilities deliver alternating current (AC) rather than DC, the conversion process used to supply the existing and forthcoming DC loads is very inefficient. This program addresses flexible DC loading/generation within buildings by using a novel building-scale energy architecture. The short-term objective is to enable DC infrastructure within buildings to incorporate DC renewable generation and storage technologies (e.g. PV solar, batteries, and fuel cells) and to supply the increasing amount of DC powered equipment directly (phasing out AC). The innovative features of this program reside in the significant efficiency gain and the cost reduction opportunity provided by the novel power conversion architecture and topologies. The elimination of conversion stages (DC/AC and AC/DC) at the generation and load anticipates a reduction in emission and the maximization building efficiency. Advances in this area will enhance the storage and delivery of power to both consumers and utility providers. From the end user perspective, the building's power architecture will accommodate maximum DC power extraction (solar, batteries, fuel cells, etc.) and the next generation of high efficiency DC powering for lightning (LED), EV chargers, HVAC/cooling (variable speed), etc. From the utility perspective, the building-scale energy system will have a perfect energy consumer profile. It will provide a predictable/reliable single-point bidirectional interface, with reactive power injection, harmonic cancellation, and storage for peak shaving/backup. These features will produce remarkable benefits for the power utility. The long-term objective is to target R&D and final implementation of a flexible, modular power converters that concentrates on definitive technical challenges associated with topological flexibility, scalability, power sharing, and control for coordinated operation for DC infrastructure. Additional objectives are to provide HQP training in renewable power and develop IP for Canadian industries. Anticipating the high demand for engineers in renewable power, the program will deliver graduates with strong R&D skills for Canada. The research program fits into the government's strategy on science and technology by helping to accelerate the deployment of renewable power and meets NSERC's objectives by bringing originality and innovation.

在过去的十年中，本地直流电流（DC）动力设备（计算机，电信，数据中心，消费电子产品）的空前扩展增加了27％。在美国/加拿大，每年消耗超过800个DC能源，产生相关的550吨有害碳排放。直到2020年，DC电力使用量将进一步增加，到2020年增加了2000万电动汽车（EV），这给一个百年历史的电力基础设施带来了重大负担。 由于电力公用事业提供交替的电流（AC）而不是DC，因此用于提供现有和即将出现的DC负载的转换过程非常低效。该程序通过使用新颖的建筑规模的能源体系结构来解决建筑物内灵活的直流负载/生成。短期目标是在建筑物内启用DC基础设施，以结合DC可再生生成和存储技术（例如PV太阳能，电池和燃料电池），并直接提供直接供电的设备（Phasing Out AC）。该计划的创新功能在于新颖的电力转换体系结构和拓扑提供的显着效率增益和降低成本机会。消除生成和负载处的转化阶段（DC/AC和AC/DC）预计发射效率和最大化建筑效率会降低。 该领域的进步将增强对消费者和公用事业提供商的储存和交付。从最终用户的角度来看，建筑物的功率体系结构将适应最大的直流电源提取（太阳能，电池，燃料电池等），以及下一代高效DC用于闪电（LED），EV充电器，HVAC/HVAC/HVAC/冷却（可变速度）等。它将提供可预测的/可靠的单点双向接口，并提供反应性功率注入，谐波取消和用于峰值剃须/备份的存储。这些功能将为电力公司带来显着的好处。 长期目标是针对研发和最终实施灵活的模块化功率转换器，该转换器着眼于与拓扑灵活性，可扩展性，功率共享和DC基础设施协调操作的控制性的确定技术挑战。其他目标是为可再生能源提供HQP培训，并为加拿大行业开发IP。该计划预期对可再生能源的工程师的需求很高，该计划将为加拿大提供强大的研发技能。该研究计划通过帮助加速可再生能源的部署并通过带来独创性和创新来实现NSERC的目标，符合政府的科学和技术战略。
