【摘要】：在含高滲透率風(fēng)電的電力系統(tǒng)中,風(fēng)電的功率波動性和有功-頻率弱慣性將對系統(tǒng)的頻率控制帶來挑戰(zhàn)。本文將針對這兩個問題,從風(fēng)機、風(fēng)電場、儲能以及電力系統(tǒng)等多個層面展開研究,尋求改善含高滲透率風(fēng)電的電力系統(tǒng)頻率控制的方法。 在風(fēng)電的功率波動性方面：首先,基于系統(tǒng)級的頻率仿真以及運行充裕性分析,分別研究風(fēng)電在分鐘到數(shù)分鐘級以及數(shù)分鐘到30分鐘級兩個時間尺度上的功率波動對系統(tǒng)頻率控制和運行充裕性的影響,并提出適用于不同系統(tǒng)的的風(fēng)電場兩個時間尺度的波動平抑指標的制定方法,為風(fēng)電與儲能示范工程的規(guī)劃和運行提供支持；然后,依托國家863課題“多類型儲能系統(tǒng)協(xié)調(diào)控制技術(shù)及示范”,提出了一種應(yīng)用于平抑風(fēng)電功率波動的儲能系統(tǒng)協(xié)調(diào)控制方法,實現(xiàn)了示范工程項目提出的兩個時間尺度的風(fēng)電功率波動平抑指標,并減小了儲能系統(tǒng)容量和功率的需求,波動平抑控制方法的效果在基于MATLAB\Simulink的時域仿真系統(tǒng)中進行了驗證。 在風(fēng)電的有功-頻率弱慣性方面：首先,提出了一種風(fēng)速自適應(yīng)的變速風(fēng)力發(fā)電機短時支持系統(tǒng)頻率的控制方法,使風(fēng)機在不同的風(fēng)速區(qū)間下以及變化的風(fēng)速下能為系統(tǒng)提供短時且穩(wěn)定的頻率支持；然后通過對變速風(fēng)力發(fā)電機的頻率支持能力以及由頻率支持產(chǎn)生的能量成本進行分析,提出了由變速風(fēng)力發(fā)電機組成的風(fēng)電場短時支持系統(tǒng)頻率的優(yōu)化控制方法,在風(fēng)電場內(nèi)對頻率支持功率進行優(yōu)化分配,降低整個風(fēng)電場的頻率支持能量成本并改善整個系統(tǒng)的頻率控制效果,整個控制方法的控制效果在基于MATLAB\Simulink的IEEE Reliability Test System (IEEE RTS)仿真系統(tǒng)中進行了驗證并與其他方法進行了對比。
[Abstract]:In the power system with high permeability wind power, the power fluctuation and active frequency weak inertia of wind power will challenge the frequency control of the system. In order to solve these two problems, this paper will study the wind turbine, wind farm, energy storage and power system from the aspects of fan, wind farm, energy storage and power system, and find out the methods to improve the frequency control of power system with high permeability wind power. In terms of power volatility of wind power: first of all, based on system-level frequency simulation and operation adequacy analysis, The effects of power fluctuations on frequency control and operation adequacy of wind power in minutes to minutes and minutes to 30 minutes are studied respectively. The formulation method of fluctuation suppression index of two time scales suitable for different systems is put forward, which provides support for the planning and operation of wind power and energy storage demonstration projects. Then, based on the national 863 project "coordinated Control Technology and demonstration of Multi-type Energy Storage system", a coordinated control method of energy storage system applied to calm wind power fluctuation is proposed. The wind power fluctuation suppression index of two time scales proposed by the demonstration project is realized, and the demand for capacity and power of the energy storage system is reduced. The effect of wave suppression control method is verified in the time domain simulation system based on MATLAB\ Simulink. In the aspect of active power-frequency weak inertia of wind power: firstly, a frequency control method of variable speed wind turbine short-time support system with adaptive wind speed is proposed. The fan can provide short-term and stable frequency support for the system under different wind speed ranges and changing wind speed. Then, through the analysis of the frequency support ability of the variable speed wind turbine and the energy cost generated by the frequency support, the optimal control method of the frequency of the short time support system of the wind farm composed of the variable speed wind turbine is put forward. The frequency support power is optimized in the wind farm, the frequency support energy cost of the whole wind farm is reduced, and the frequency control effect of the whole system is improved. The control effect of the whole control method is verified in the IEEE Reliability Test System (IEEE RTS) simulation system based on MATLAB\ Simulink and compared with other methods.
