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，在现代电网中，存在过多的可再生能源(RESS)和分布式能源(DER)，例如风能和光伏(PV)系统，以及通信和监测系统(同步相器网络)。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)解决日益增长的能源消耗，(3)减少长距离输电线路的电力损失，以及(4)减少对石油行业的依赖。然而，由于可再生能源的间歇性、缺乏足够成熟的储能技术、具有不同资源和技术的发电组合日益多样化以及同步相量网络易受通信损害(例如数据丢失、网络攻击)的影响，实现这类智能电网必须克服与电力系统的安全性、稳定性、系统可靠性、电网复原力和最佳电力管理相关的一些重大技术挑战。拟议的研究计划将开发一种增强型同步相量辅助控制框架，使未来的电网能够克服上述挑战。该框架包括(1)先进的初级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)用于性能评估的联合仿真试验台。我将为DER设计新的控制器，以克服与现实电网相关的不可避免和微妙的挑战。同步相量网络将测量的同步相量数据传输到相量数据集中器，在那里处理数据集以提高其完整性和质量。在二次控制层，处理后的数据被用来计算控制命令，以优化DER的协调。该协同仿真平台提供了电力系统元件、同步相量网络和DER控制器的多种形式的操作集成。这一研究计划带来了先进的强大控制器和可靠的同步相量网络，使DER能够以前所未有的水平集成到电网中。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、能效、可靠性、弹性和可持续性。拟议的研究计划的结果可以显著减少危及供应安全的服务中断和停电的持续时间，目前北美每年的损失超过1400亿美元。此外，拟议的研究计划将为加拿大工业提供推进技术前沿的新想法。它还将促进传播具有新想法的有影响力的研究，并使加拿大总部成为权力和能源领域的有影响力的领导者。

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.
