【正文】 取系統(tǒng)直流母線電壓為被控量，由圖 2－ 6可得系統(tǒng)的數(shù)學(xué)模型： 其中 EMBED — 直流母線電壓， EMBED — 風(fēng)力發(fā)電裝置輸出電流， EMBED — 太陽能發(fā)電裝置輸出電流， EMBED — 系統(tǒng)輸送到負載得電流， EMBED — 電網(wǎng)輸送電直流部分得電流，Ｃ — 直流平波電容容量。 數(shù)據(jù)庫是存放所有輸入、輸出變量的全部模糊子集的隸屬度關(guān)系的矢量值；若論域為連續(xù)域，數(shù)據(jù)庫則為相應(yīng)的隸屬函數(shù)。 3. 模糊控制 模糊集合和模糊控制的概念是由美國加利福尼亞大學(xué)著名教授 Ｌ．Ａ．Ｚａｄｅｈ在其 Fuzzy Sets， Fuzzy Algorithm 和 Rationale for Fuzzy Control 等著名論著中首先提出一種完全不 同于傳統(tǒng)數(shù)學(xué)與控制理論的智能理論。由于系統(tǒng)的負荷是由直流電壓經(jīng)逆變器提供的，直流電壓的穩(wěn)定性直接影響系統(tǒng)給負載提供電能的質(zhì)量，在這里取系統(tǒng)直流母線電壓 EMBED 為系統(tǒng)的被控量，并取其工作范圍為 192Ｖ－ 240Ｖ，選擇 216Ｖ為直流部分的額定電壓。 能量管理系統(tǒng)：根據(jù)數(shù)據(jù)采集系統(tǒng)提供的系統(tǒng)各功能單元運行參數(shù)，來實現(xiàn)對系統(tǒng)的有效管理和控制。有條件時通過搭配適當(dāng)容量的蓄電池或接入市電作為備用電源，可使運行費用大大的降低、供電的可靠性大大的提高。s is a system to output the exchanges electric power quantity, stability and dependable key factors. As a result the choice direct current is part of physically the direct current electric voltage EMBED measure with the direct current electric voltage variety EMBED , be the first degree importation of the system, output for the direct current electric voltage etc. the effect be worth EMBED EMBED is a prehensive direct current electric voltage EMBED measure with the direct current electric voltage variety EMBED , get EMBED future appearance. Substantially, it reflected the system on the current direct current electric voltage foundation, if don39。 If in order to continue the area, the theory area database then for belong to the function correspond. The regular storehouse is the operator which and has the rich experience based on the expert knowledge acts according to the longterm accumulation the experience, according to person39。 When EMBED ＝１ mean that the charged barbed wire connects into the admixture to generate electricity the system, EMBED ＝ 0 mean that the charged barbed wire generates electricity the system from the admixture to cut off。Energy Management System of Admixture Electricitygenerating 1. One preface The admixture that wind force and solar cells generate electricity to constitute generates electricity the system and is called the breeze/ light to repair the system with each other, all having some mon weakness because of the breeze and solar energies, such as the energy density low, the stability is bad and is subjected to the weather influence not to continue, have the strong weak conjugation, solar energy of seasonal to interrupted etc. day and night. Be generate electricity by the wind force and solar energy respectively to the power supply, the credibility of its power supply lowers consumedly. The wind energy, solar energy has to repair sex with each other certainly, if the sun light of daytime is strong, the night breeze is many, the summer sunshine good, the breeze is weak。 EMBED ＝１ mean that two loads connect into the admixture to generate electricity the system devotion work, EMBED = 0 mean that two loads generate electricity the system excision from the admixture. Aim at the characteristics of the system movement, draw up the following design rule: (1)Rule a A power of the breeze electrical engineering capacity that constitutes to mix with to generate electricity the system is more and greatly, as a result the choice regard a power supply of the breeze electrical engineering as principle, the solar cell array is the energy tiny adjust the part. (2)Rule two According to the system work characteristic, takes the direct current side terminal voltage EMBED expected value is 216 V, when the renewable energy may output the maximum work rate is bigger than the load request, the renewable energy to the electrical work does not transport the electrical energy. (3)Rule three Takes when here the direct current generator voltage is lower than 192 V, through incorporates the controller to put through the electrical work, by the city electricity supplemented the load needs the short partial electrical energies, and the incorporation controller which the chapter introduced by this article behind causes the direct current generator voltage to maintain 192 V, namely EMBED ＝１ When attracts 200 V, closure incorporation controller, then EMBED = 0 (4)Rule four Two loads are several: Generate electricity the system for the admixture in the electric power that the assistance facilities need, when can the renewable energy exportation electric power contain surplus of energy, the load that just throw in. In two kind of loads working condition, its load power examination has not been more difficult, in order to avoid two kind of loads frequently throwing 。s intuition inference one language expression form. Most monly used is if then, else, also, or and so on, like 2 Uyghur fuzzy inference rule maybe represented as R: If (deviation is a。t change the control quantity, then next sample the estimate value of the time direct current side electric voltage is EMBED , because of before next adoption period arrival, the exportation control of the system quantity, was reason logically by faintness personal occurrence change, as a result define here EMBED be worth for the etc. effect of parts of electric voltages of the system direct current. Second degree with the first degree output39。 目前國內(nèi)主要針對獨立的風(fēng)力發(fā)電、光伏發(fā)電及風(fēng)一光互補發(fā)電控制系統(tǒng)的研究較多。 緩沖電容：實現(xiàn)系統(tǒng)直流部分電壓的平穩(wěn)。為了不使系統(tǒng)的結(jié)構(gòu)過于復(fù)雜，在這里對蓄電池的處理不予以考慮。它的產(chǎn)生不僅拓廣了經(jīng)典數(shù)學(xué)的數(shù)學(xué)基礎(chǔ)，而且是使計算機科學(xué)向模擬人類思維方面發(fā)展的重大突破。 規(guī)則庫是基于專家知識和有豐富經(jīng)驗的操作人員根據(jù)長期積累的經(jīng)驗，按人的直覺推理的一 種語言表示形式。 通?？稍偕茉窗l(fā)電裝置的投資較大，為了充分發(fā)揮其發(fā)電的效率，縮短系統(tǒng)成本的回收周期，發(fā)電裝 置多采用最大功率輸出為控制目標。 由系統(tǒng)的結(jié)構(gòu)圖可知，系統(tǒng)直流母線電壓的變化直接影響系統(tǒng)給負載提供電能的質(zhì)量和可靠性，因而穩(wěn)定的直流電壓是系統(tǒng)工作可靠 性和性能的一個重要指標。 （ 2）知識庫 知識庫描述形式主要有兩種：數(shù)據(jù)庫和規(guī)則庫。 二類負載未工作情況下，其負載功率檢測較困難，為了避免二類負載的頻繁投徹 ；本文根據(jù)系統(tǒng)的負載配置情況，設(shè)二類負載最大功率為 EMBED ，當(dāng) EMBED + EMBED ＞ EMBED + EMBED 把二類負載投入運行，即 EMBED ＝ 1 （ 5）規(guī)則五 為了提高系統(tǒng)直流部分電壓的穩(wěn)定性，當(dāng)吸＜２０４Ｖ時，把二類負載從系統(tǒng)中
