【摘要】：電力彈簧(Electric Spring,ES)是一種分布式電壓調(diào)節(jié)器,能有效緩解分布式發(fā)電系統(tǒng)中出現(xiàn)的電力波動(dòng)問(wèn)題。但是在現(xiàn)有控制器調(diào)節(jié)下易引入諧波,且響應(yīng)時(shí)間較長(zhǎng),嚴(yán)重影響了電力彈簧的調(diào)節(jié)效果。針對(duì)比例積分和比例諧振控制器應(yīng)用于ES這個(gè)非線性復(fù)雜系統(tǒng)上穩(wěn)定性和魯棒性較差的特點(diǎn),本文應(yīng)用改進(jìn)的單純型加速算法(simplexmethod,SPX),以時(shí)間乘以誤差平方積分準(zhǔn)則作為尋優(yōu)目標(biāo)函數(shù),對(duì)PI控制器的參數(shù)進(jìn)行實(shí)時(shí)調(diào)整、尋優(yōu),使ES的動(dòng)態(tài)響應(yīng)效果達(dá)到最佳。本文在閱讀大量參考文獻(xiàn)后,對(duì)電力彈簧的模型和工作特性進(jìn)行研究。在這個(gè)基礎(chǔ)上探討了現(xiàn)有電力彈簧控制器的設(shè)計(jì)及不足之處,并在Matlab/Simulink環(huán)境中對(duì)電力彈簧的PR控制器進(jìn)行仿真,發(fā)現(xiàn)傳統(tǒng)控制器響應(yīng)慢、穩(wěn)定性差的問(wèn)題�？紤]到電力彈簧屬于分布式電壓調(diào)節(jié)器,需要較強(qiáng)適應(yīng)性和魯棒性,本文設(shè)計(jì)了基于最優(yōu)比例積分的電力彈簧控制器。為了對(duì)比其控制效果,還設(shè)計(jì)了同樣具有良好靜態(tài)和動(dòng)態(tài)性能的模糊PI控制器。仿真和對(duì)比結(jié)果表明最優(yōu)比例積分控制器效果更佳。最后,為了驗(yàn)證基于最優(yōu)比例積分控制器的電力彈簧能適用于新能源發(fā)電系統(tǒng),在Matlab/Simulink環(huán)境下搭建了光伏并網(wǎng)模型。仿真結(jié)果驗(yàn)證電力彈簧在光伏發(fā)電系統(tǒng)中具有良好的靜態(tài)和動(dòng)態(tài)性能,能緩解新能源發(fā)電系統(tǒng)中出現(xiàn)的電力波動(dòng)問(wèn)題。
[Abstract]:Power spring spring spring ESs is a kind of distributed voltage regulator, which can effectively alleviate the problem of power fluctuation in distributed generation system, but it is easy to introduce harmonics under the regulation of the existing controller, and the response time is longer. The regulation effect of power spring is seriously affected. In view of the poor stability and robustness of the proportional integral and proportional resonance controller applied to the nonlinear complex system es, In this paper, the improved simplex acceleration algorithm is used to optimize the parameters of Pi controller by using the time multiplied error squared integral criterion as the optimization objective function. The dynamic response of es is optimized. After reading a large number of references, this paper studies the model and working characteristics of power spring. On this basis, the design and shortcomings of the existing power spring controller are discussed. The PR controller of power spring is simulated in Matlab/Simulink environment. It is found that the traditional controller is slow in response and poor in stability. Considering that power spring is a distributed voltage regulator, it needs strong adaptability and robustness. In this paper, a power spring controller based on optimal proportional integral is designed. A fuzzy Pi controller with good static and dynamic performance is also designed. The simulation and comparison results show that the optimal proportional integral controller is more effective. Finally, In order to verify that the power spring based on the optimal proportional integral controller is applicable to the new energy generation system, A grid-connected photovoltaic model is built in the Matlab/Simulink environment. The simulation results show that the power spring has good static and dynamic performance in photovoltaic power generation system and can alleviate the power fluctuation problem in the new energy generation system.
