my country's power grid develops rapidly,With large -scale wind and photovoltaic power generation,The continuous investment of the long -distance passing DC power project,Regional grid changes from synchronous to asynchronous networking,The degree of coupling of the power information system and the physical system is continuously deepened,The characteristics of the power system oscillation、Factors and control methods have changed significantly,In recent years, the grid has appeared multi -type oscillating related to time stagnation,Bring great harm to the safe operation of the system。Power grid equipment information communication and controller m88 sports bettingexecution agencies commonly existed,The occurrence of oscillation、Development and controlling controller design is very significant。Traditional time -like treatment method causes the system model to be not fine、Inaccurate oscillation analysis、Poor performance of the controller of the oscillating control,It is difficult to meet the safe and stable operation requirements of the power grid,Unexpectedly need to be a large -scale stagnant power system oscillation analysis and control technology。

Plan at the National 863、Natural Science Fund、With support of the technology project of the State Grid Corporation,The team breaks through the high -precision model of the time stagnation power system、Key features of key feature value and multiple types of oscillation coordination control key technologies,Established a large -scale stagnation power system oscillation analysis and control technology system,Realized promotion and application。Main technical innovation as follows:

(1) The first lapse power system spectrum discrete m88 live casino gamesand high -precision modeling theory,Eliminate the infinite dimension in the model modeling of the time stagnation system,Precise calculation of the characteristic value of the current stagnant power system is transformed from uncomfortable to feasible solution.。The characteristic value obtained by the modeling theory has spectrum accuracy,Error is less than 1E-1,Time stagnation adaptation range width,Covering MS -level to 10S -level stagnation situation,Lay the model foundation for the multi -type oscillating analysis and coordination control based on the characteristic value。

(2) The matrix decomposition and spectrum transformation technology of the key characteristic value of the key characteristic value of the system,Breaking through the large -scale stagnation power system feature value calculation efficiency and convergence difficulty bottleneck,Promote the feature value from linear convergence to secondary convergence,Has achieve efficient obtaining key characteristic values,The first international M88 Online Live Casinoset of international stagnation power system features and high -efficiency computing commercial software,Successfully applied to the oscillation analysis of the DC Internet Power Grid in my country。

(3) The controller interaction affects quantitative assessment method,It proposed the oscillating source based on the theory of empirical modular theory.,Positioning is accurate and misjudgment,Time is shortened by more than two times compared to the traditional method; breakthroughs based on feature value optimization methods、Multi -device controller parameter coordinated design problem,Multi -type oscillation analysis and coordinated control device based on wide -area information,Realized effective inhibitory and engineering application of multiple types of oscillations。

For the past 5 years,21 items of authorized invention patents、2 items soft,Apply for 1 international patent PCT; publish 12 SCI papers、EI papers more than 20 articles,Among them, the top power journal IEEE TRANSACTIONS on Power m88 com live casino registerSystems papers are 10; publishing monograph 1。IEEE FEEE FELLOW、The appraisal committee of Academician Cheng Shijie of the Chinese Academy of Sciences believes that "the project has achieved original results in the theory and technology of the characteristics of the characteristics of the characteristics of the stagnation power system at a large scale,Generally at the international leading level "。Related achievements won the second prize of scientific and technological progress in Shandong Province in 2021。
