Our institute’s complex power grid security prevention and control and intelligent recovery team is working in the Key Laboratory of Power Grid Intelligent Dispatching and Control of the Ministry of Education、Supported by the National Natural Science Foundation of China and the National Key Research and Development Program，passedContinuous construction for more than 6 years，Preliminary completion of complex power grid simulation and analysis research platform，Provide uninterrupted online simulation and analysis services for teachers and students during the COVID-19 epidemic，Ensures the continued development of scientific research and learning for teachers and students。
In order to meet the needs of complex power grid research, the platform has gradually expanded by7Hardware resource pool composed of high-performance servers，Available up to 1 second2Trillions of sums22Trillion doublesCPU and GPU computing power。The platform deploys professional power grid simulation software，Including the open source software STEPS developed by the team，and PSASP、BPA、PSS/E、Power Factory、PSCAD and other commercial software，and TensorFlow、Keras and other mainstream artificial intelligence modules。
The platform has been proactively aiming to provide online services since the beginning of its construction，Meet the remote access needs of teachers and students。During the sudden new crown epidemic this year，Platform administrator Li Changgang promptly maintains service accounts for teachers and students in need、Upgrade professional software，Ensures the normal operation of the platform。The platform’s powerful computing power and stable remote service capabilities，Continuously carry out scientific research and learning for teachers and students，Provides strong software and hardware support。
In response to the school’s instructions regarding graduation and employment，The platform proactively provides convenience to graduating students，Ensure that writing his thesis is not delayed due to the epidemic。Graduating doctoral student Sun Runjia:“During the epidemic, IHigh of remote calling platformPerformanceCalculationResource developmentComputational example simulation, successfully completed the graduation thesis，The stability of the platform is also guaranteed了Reliable storage of important materials such as graduation thesis.”
To ensure the smooth progress of the project research undertaken by the team，The platform rapidly expands software functions based on relevant project needs，Ensure that relevant research is not suspended due to the epidemic。Ph.D. student Zhu Yuanzhen:“During the epidemic，The national key research and development plan project I participated in requires progress as planned，But I lack simulation software on my personal computer，The computing power is also significantly insufficient。With the help of platform STEPS multi-thread parallel function，I am in timeCompletedProjectData generationandModel construction, guaranteedCertificateEnabled the smooth implementation of national important projects.”
To support online teaching during the epidemic，The platform also provides necessary learning resources to students of all levels。Chang Yanchao, a first-year master’s student:“During the epidemic, I used the platform STEPS at homeComplete了Simulation experiment of power system dynamic analysis course, usingPlatformPSS/E implementation了Optimum power flow calculation of power system safe and economical operation courseReport, the platform lets meatHomeThat’s itEnjoyToThe school’s high-quality experimental conditions。”
With the support of the National Key R&D Program，Platform overcomes the adverse impact of the epidemic，In this yearThe prototype of the new generation power grid control system was deployed in March，By Li Changgang、Yan Jiongcheng、Zhu Yuanzhen、Li Huarui、Project software research and development team composed of teachers and students such as Qi Hang，Remotely connect to the prototype system，Actively carry out research and development of intelligent situational awareness and early warning software for large power grid security risks，Step up work to ensure the smooth implementation of national important projects。
During the epidemic，The team strictly implements epidemic control regulations，Make full use of the remote service capabilities of the complex power grid simulation and analysis platform，Provide high-quality software and hardware scientific research resources for teachers and students，Under the unfavorable conditions where teachers and students cannot return to school normally，Ensures the continuation of scientific research and learning。The construction of this platform also actively explores the construction of scientific research laboratories and platform integration in our institute，The platform will continue to expand its functions according to the needs of the college，Promote the construction of high-level scientific research capabilities in the college。
Complex power grid security prevention and control and intelligent recovery team is nearyearFruitable achievements in theory and practice，The theoretical system for eigenvalue calculation and stability analysis of large-scale time-delay power systems established by Ye Hua has been at the leading international level，Our institute’s first five-million-level power grid security defense project presided over by Li Changgang has been implemented，TeamThe development momentum of "standing up to the sky and the ground" is getting stronger and stronger.
