The increased awareness for environmental preservation and the desire to reduce greenhouse gas emissions has caused a higher utilization of distributed renewable energy sources. As a result, the electrical grid is changing from utilizing large, remote fossil-fuel based generators to smaller, locally-embedded renewable energy generators. Deregulation has caused increased competition within the industry and a desire for improved efficiency. Furthermore, with the convergence of different technologies such as power systems, power electronics, information technology, communication and sensors, the grid can now be transformed into a truly smart grid capable of operating in a highly coordinated manner through intelligent management systems to realize its full potential.***My research program concentrates on system studies to demonstrate the opportunities and expose the weaknesses in the smart grid implementation. The problems that will be studied relate to: ***- Two-way power flow in the feeders and its impact on critical grid components such as transformers which will be subjected to frequent energizing/de-energizing cycles. This will lead to reduced equipment life-span due to voltage stresses and other power quality issues (such as harmonic generation).***- Smart grid components i.e. fault current limiters, transfer switches and other protection equipment needed to coordinate the integration of both legacy and modern-age equipment.***- Renewable energy integration issues which will need advanced converters and their controllers to feed in power from a variable voltage/frequency into a grid that is operating at a fixed voltage/frequency. Conservation and Demand Management (CDM) issues specially taking advantage of storage components and Time-of-Use controllers. ***Although transformation of the legacy grid towards the new smart grid has already begun, its full implementation may take decades before reaching a desired level of operational flexibility, security and efficiency. This research will be useful for power utilities, consultants and manufacturers of electrical equipment. It will benefit the power system planners, operators and commissioning members of utilities. This research will provide ample opportunities for the training of HQP and allow university collaboration with local distribution companies (LDCs), consultants and manufacturers. The intellectual property generated will provide deeper insight into smart grid behavior and operation. There is a global shortage of HQP in this field. The next decade will see huge investments in infrastructure for the renewal of the aging legacy grid components.**

环境保护意识的增强和减少温室气体排放的愿望导致分布式可再生能源的利用率更高。因此，电网正在从使用大型远程化石燃料发电机转变为小型本地嵌入式可再生能源发电机。放松管制导致行业内竞争加剧以及提高效率的愿望。此外，随着电力系统、电力电子、信息技术、通信、传感器等不同技术的融合，通过智能管理系统，电网可以转变为真正高度协调运行的智能电网，实现电网的全面覆盖。潜力。***我的研究项目集中于系统研究，以展示智能电网实施中的机会并暴露其弱点。将研究的问题涉及： ***- 馈线中的双向功率流及其对关键电网组件（例如变压器）的影响，这些组件将经历频繁的通电/断电循环。由于电压应力和其他电能质量问题（例如谐波产生），这将导致设备寿命缩短。***- 智能电网组件，即故障电流限制器、转换开关和协调两者集成所需的其他保护设备传统和现代设备。***- 可再生能源集成问题，需要先进的转换器及其控制器将来自可变电压/频率的电力馈入以固定电压/频率运行的电网。节约和需求管理 (CDM) 问题特别利用存储组件和使用时间控制器。 ***尽管传统电网向新智能电网的转型已经开始，但其全面实施可能需要数十年时间才能达到所需的运营灵活性、安全性和效率水平。这项研究将对电力公司、顾问和电气设备制造商有用。它将有利于电力系统规划者、运营商和公用事业公司的调试人员。这项研究将为 HQP 的培训提供充足的机会，并允许大学与当地分销公司 (LDC)、顾问和制造商合作。所产生的知识产权将为智能电网行为和运营提供更深入的见解。全球范围内该领域的高素质人才短缺。未来十年将出现对基础设施的巨额投资，以更新老化的遗留电网组件。**
