A microgrid is formed by coordinating the operation of distributed generators (DGs), energy storage devices, and controllable loads in a section of distribution grid so that it can operate in parallel with the grid or as an autonomous power island. Microgrids provide an attractive structure to integrate small-scale generation based on renewable energy resources and energy efficient technologies such as combined heat and power (CHP) generation, and demand responsive loads. However, there are several technical challenges encountered in implementation of microgrids, especially when the generation is from the intermittent sources such as wind and solar photovoltaic (PV). These challenges include coordination of the fault protection in microgrids during both parallel and islanded modes of operation; detection of faults when the generators have limited fault current contributions; optimal use of energy storage and generation resources in islanded microgrids; and control of generation and energy storage to ensure voltage and frequency stability during disturbances. My research aims to develop a range of effective and economical protection solutions suitable for variety of microgrid designs using synchrophasor measurements, transient signals generated by faults, and hybrid approaches. This research will also develop cost effective control and communication structures needed to implement the protection and control functions in a microgrid, and energy management strategies for optimizing the utilization of renewable energy resources. As part of the research, a microgrid test bed that facilitates testing of new technologies through hardware-in-loop simulations will also be developed. The expected outcomes are robust protection, control and operational strategies that enable widespread implementation of microgrids. My research program is expected to provide training to five Ph.D. and two M.Sc. students.

通过协调分布式发电机（DGS），储能设备和可控载荷的操作来形成微电网，以便它可以与网格或自动岛自动岛平行运行。微电网提供了一个有吸引力的结构，以基于可再生能源资源和能源有效技术（例如加热和功率（CHP）生成）以及需求响应载荷的措施来整合小规模生成。但是，在微电网实施中遇到了一些技术挑战，尤其是当发电来自Wind和太阳能光伏（PV）等间歇来源时。这些挑战包括在平行和岛屿操作模式下微电网中断层保护的协调；当发电机的故障电流贡献有限时，检测故障；在岛的微电网中最佳利用储能和发电资源；并控制发电和能量存储，以确保干扰期间的电压和频率稳定性。 我的研究旨在开发一系列有效且经济的保护解决方案，适用于使用同步测量的测量值，故障产生的瞬态信号以及混合方法。这项研究还将开发出在微电网中实施保护和控制功能所需的成本有效控制和沟通结构，以及优化可再生能源利用的能源管理策略。作为研究的一部分，还将开发通过硬件式仿真来促进新技术测试的微电网测试床。预期的结果是强大的保护，控制和操作策略，可以广泛实施微电网。 我的研究计划有望为五个博士提供培训。和两个M.Sc.学生。
