【摘要】：社會經(jīng)濟發(fā)展、環(huán)境問題、資源匱乏帶來了人類尋求新能源的壓力,風能和太陽能等新型環(huán)保可再生能源的重要性日益凸顯,但其固有的隨機性、間歇性等缺點都嚴重制約著其廣泛應用,由于風能和太陽能在時間及空間上具有互補性,因此風光互補發(fā)電系統(tǒng)無疑是未來可再生能源發(fā)電系統(tǒng)的主要研究方向,但是風光互補發(fā)電系統(tǒng)的輸出功率具有波動性,且如何將風能和太陽能進行有效存儲都是目前亟需解決的問題,針對上述問題,本文進行了如下研究：首先,介紹風力發(fā)電系統(tǒng)和光伏發(fā)電系統(tǒng)的輸出特性,通過分析兩種發(fā)電系統(tǒng)在時間上和空間上的互補性及其能夠相互平抑的特點,引出發(fā)展風光互補發(fā)電系統(tǒng)的必要性。同時通過分析蓄電池和超導儲能的特性,將蓄電池和超導儲能組成混合儲能裝置,從而滿足整個系統(tǒng)的經(jīng)濟成本和利用效率。其次,為減少風光互補發(fā)電系統(tǒng)中諧波分量的波動性,利用儲能裝置和濾波裝置對有功功率電流和無功功率電流控制結構相似性,本文將儲能裝置作為濾波裝置使用,將風光互補發(fā)電系統(tǒng)的輸出電流中諧波部分通過控制進行濾波,為提高濾波效率,提出自適應Prony互信息特征提取算法,分析諧波電流之間的互信息。為了提高平抑效率,本文通過對儲能裝置的電壓和電流進行控制來實現(xiàn)對混合儲能系統(tǒng)的控制,并引用自適應模糊控制算法,通過對蓄電池和超導儲能的充放電狀態(tài)進行分析,從而提高儲能系統(tǒng)響應的準確性和快速性。最后,為驗證風光互補發(fā)電系統(tǒng)的有效性,通過PSCAD/EMTDC仿真軟件建立基于混合儲能裝置的風光互補發(fā)電系統(tǒng),通過仿真結果可知,將儲能裝置作為濾波裝置使用,也可降低風光互補發(fā)電系統(tǒng)輸出功率的諧波含量,從而進一步降低對儲能裝置的影響；在混合儲能裝置的作用下,風光互補發(fā)電系統(tǒng)輸出功率趨于穩(wěn)定,混合儲能裝置可提高蓄電池的使用壽命、降低系統(tǒng)成本、提高儲能裝置利用率。
[Abstract]:Social and economic development, environmental problems and lack of resources have brought about the pressure of human beings to seek new energy sources. The importance of new environmentally friendly renewable energy such as wind energy and solar energy is becoming increasingly prominent, but its inherent randomness. Because wind energy and solar energy are complementary in time and space, wind and solar power systems are undoubtedly the main research direction of renewable energy generation system in the future. However, the output power of wind-wind complementary power generation system is volatile, and how to store wind energy and solar energy effectively is a problem that needs to be solved at present. In view of the above problems, this paper has carried out the following research: first of all, This paper introduces the output characteristics of wind power generation system and photovoltaic power generation system. By analyzing the complementarity between the two systems in time and space and their ability to stabilize each other, the necessity of the development of wind power generation system and photovoltaic power generation system is introduced. At the same time, by analyzing the characteristics of storage battery and superconducting energy storage, the hybrid energy storage device is made up of the storage battery and superconducting energy storage, so as to meet the economic cost and utilization efficiency of the whole system. Secondly, in order to reduce the fluctuation of harmonic component in the wind and wind complementary generation system, the energy storage device is used as the filter device to control the active power current and reactive power current by using the energy storage device and the filter device to control the active power current and the reactive power current. In order to improve the filtering efficiency, an adaptive Prony mutual information feature extraction algorithm is proposed to analyze the mutual information between harmonic currents. In order to improve the stabilization efficiency, the control of the hybrid energy storage system is realized by controlling the voltage and current of the energy storage device, and the self-adaptive fuzzy control algorithm is used to analyze the charging and discharging state of the storage battery and superconducting energy storage system. In order to improve the accuracy and rapidity of energy storage system response. Finally, in order to verify the effectiveness of the wind and wind complementary power generation system, a hybrid energy storage system based on the hybrid energy storage unit is established by PSCAD/EMTDC simulation software. The simulation results show that the energy storage device is used as a filter device. It can also reduce the harmonic content of the output power of the wind and wind complementary power generation system, thus further reducing the influence on the energy storage device. Under the action of the hybrid energy storage unit, the output power of the wind power complementary generation system tends to be stable. The hybrid energy storage device can increase the service life of the battery, reduce the system cost and improve the utilization ratio of the energy storage unit.
