A Synchrophasor-Assisted Control Framework for Improving Power Quality, Reliability, and Resiliency of Modern Power Systems

电力系统正在经历从传统电网向现代电网的范式转变，其中存在大量可再生能源（RESs）和分布式能源（DERs），例如风能和光伏（PV）系统，以及通信和监测系统（同步相量网络）。这一引人注目的转变背后的激励因素包括：(1)减少温室气体排放，(2)解决不断增长的能源消耗，(3)减少长距离输电线路的电力损失，(4)减少对石油工业的依赖。然而，由于可再生能源的间歇性、缺乏足够成熟的储能技术、资源和技术不同质的发电组合的多样化以及同步网络对通信障碍（如数据丢失、网络攻击）的脆弱性，实现这种智能电网必须克服与安全性、稳定性、系统可靠性、电网弹性等相关的一系列重大技术挑战。以及最佳的电源管理。拟议的研究计划将开发一种增强的同步相量辅助控制框架，以使未来的电网能够克服上述挑战。提出的框架包括(1)先进的一级DER控制系统，(2)包括相量测量单元（PMU）数据处理方案和二级控制的同步相量网络，以及(3)性能评估的联合仿真试验台。我将为DERs设计新颖的控制器，以克服与现实生活中的电网相关的不可避免的微妙挑战。同步相量网络将测量到的同步相量数据传输到相量数据集中器，在那里对数据集进行处理以提高其完整性和质量。在二级控制层，使用处理后的数据计算控制命令，以实现der的最优协调。联合仿真平台提供了电力系统组件、同步相量网络和DER控制器的多种形式的运行集成。该研究项目将带来先进的鲁棒控制器和可靠的同步相量网络，从而使分布式电源与电网的集成达到前所未有的水平。所开发的控制器与同步相量数据处理算法相结合，将提高现代电网的电能质量、能源效率、可靠性、弹性和可持续性。拟议研究计划的结果可以显著减少服务中断和停电的持续时间，这些中断和停电危及供应安全，目前每年在北美造成的损失超过1400亿美元。此外，拟议的研究计划将为加拿大工业提供新颖的想法，以推进技术前沿。它还将促进具有新颖思想的有影响力的研究的传播，并使加拿大HQP成为电力和能源领域有影响力的领导者。

The electrical power system is undergoing a paradigm shift from the conventional power grid towards a modern grid wherein a plethora of renewable energy sources (RESs) and distributed energy resources (DERs), e.g., wind and photovoltaic (PV) systems, along with communication and monitoring systems (synchrophasor networks) are present. The motivating factors behind this compelling shift include (1) mitigating greenhouse gas emissions, (2) addressing ever-increasing energy consumption, (3) reducing power losses over long transmission lines, and (4) reducing the dependence on the oil industry. Nevertheless, due to the intermittent nature of RES, lack of sufficiently mature energy storage technology, increased diversification of generation portfolios with inhomogenous resources and technologies, and vulnerability of synchrophasor networks to communication impairments - e.g., data loss, cyber-attacks - the realization of such smart grids has to overcome a number of major technical challenges associated with safety, stability, system reliability, grid resiliency, and optimal power management of DERs. The proposed research program will develop an enhanced synchrophasor-assisted control framework to enable the future grid to overcome the aforementioned challenges. The proposed framework includes (1) advanced DER control systems at primary level, (2) a synchrophasor network including phasor measurement unit (PMU) data processing schemes and secondary level control, and (3) a cosimulation test-bed for performance evaluation. I will devise novel controllers for DERs to overcome the inevitable and subtle challenges associated with real-life power grids. The synchrophasor network transmits measured synchrophasor data to phasor data concentrators, where datasets are processed to enhance their integrity and quality. At the secondary control layer, the processed data are used to calculate the control commands for optimal coordination of DERs. The cosimulation platform provides multi-formalism operational integration of power system components, synchrophasor network and DER controllers. This research program leads to advanced robust controllers and reliable synchrophasor networks to enable unprecedented levels of integration of DERs into the grid. The developed controllers combined with synchrophasor data processing algorithms will improve power quality, energy efficiency, reliability, resiliency, and sustainability of modern power grids. The outcomes of the proposed research program can significantly decrease the duration of service interruptions and power outages that jeopardize the supply security and currently cost over $140 billion annually in North America. Moreover, the proposed research program will equip Canadian industries with novel ideas to advance the technological frontiers. It will also promote the dissemination of impactful research with novel ideas, and empower Canadian HQP to become influential leaders in the field of power and energy.
