In order to reduce harmful CO2 emissions, a concerted effort has been made by governments worldwide to produce more electricity from renewable energy sources such as wind and solar. Although both provide clean sources of energy and do not produce emissions, they are intermittent in nature. As the use of these renewable yet intermittent sources increases, there is increased concern for the reliability of the power grid. Energy storage technologies play a critical role in the efficient operation of the power grid by: ensuring availability during periods of high demand, smoothing fluctuations in supply and demand, and enhancing grid reliability. Newer battery technologies not only provide energy storage for small systems but can also provide significant energy storage for utility-scale systems. This proposal focuses on the development of novel, efficient, compact and cost-effective power conversion technology for energy storage systems. The innovative character of this research lies in the uniqueness of proposed alternatives to existing converter topologies and control techniques. The main emphasis is on devising minimum-components, highly-efficient and very-high switching circuit topologies and digital control techniques that enable the mass scale deployment of energy storage systems. Due to the advanced research being conducted at ePOWER as well as the close collaborations nutured with industrial partners, the applicant's HQP will gain a unique opportunity to acquire broader-based industry-relevant and application-based experience not common in academia. The advanced solutions obtained through the proposed research are expected to provide a competitive edge to Canadian industries to penetrate this burgeoning market. Proliferation of this energy-efficient technology in other industries, such as the information, alternative energy and aerospace sectors, will further benefit Canada. The proposed research will also help Canada to fulfill its commitment to the Kyoto Protocol in reducing greenhouse gas emissions.

为了减少有害的二氧化碳排放，世界各国政府已经做出了一致的努力，从风能和太阳能等可再生能源中生产更多的电力。 虽然两者都提供清洁能源，不产生排放，但它们在本质上是间歇性的。随着这些可再生但间歇性能源的使用增加，人们对电网的可靠性越来越关注。储能技术在电网的高效运行中发挥着至关重要的作用：确保高需求时期的可用性，平滑供需波动，提高电网可靠性。更新的电池技术不仅可以为小型系统提供能量存储，还可以为公用事业规模的系统提供重要的能量存储。该提案的重点是开发用于储能系统的新型、高效、紧凑且具有成本效益的功率转换技术。 这项研究的创新性在于现有的转换器拓扑结构和控制技术的独特性，建议的替代品。主要重点是设计最少元件、高效和极高开关电路拓扑和数字控制技术，以实现储能系统的大规模部署。 由于ePOWER正在进行的先进研究以及与工业合作伙伴的密切合作，申请人的HQP将获得一个独特的机会，以获得更广泛的行业相关和基于应用的经验，这在学术界并不常见。 通过拟议的研究获得的先进解决方案预计将为加拿大工业提供竞争优势，以渗透到这个新兴的市场。在信息、替代能源和航空航天部门等其他行业推广这一节能技术将使加拿大进一步受益。拟议的研究还将有助于加拿大履行其对《京都议定书》在减少温室气体排放方面的承诺。
