【摘要】：隨著化石能源的日益枯竭,以及新型能源的不斷開發(fā),分布式發(fā)電這種環(huán)保性強(qiáng)、靈活性高和模塊化的高效新型發(fā)電方式展現(xiàn)了廣闊的發(fā)展前景。但是分布式電源的大量接入為電網(wǎng)增加了多種不利因素。微電網(wǎng)技術(shù)的出現(xiàn)使得問(wèn)題的解決出現(xiàn)了轉(zhuǎn)機(jī)。該技術(shù)受到了更加廣泛的關(guān)注,因此對(duì)分布式發(fā)電及微電網(wǎng)技術(shù)進(jìn)行研究具有重要意義。 目前相關(guān)研究中,光伏電池仿真模型眾多,但沒(méi)有系統(tǒng)的分類；很多光蓄混合發(fā)電系統(tǒng)的設(shè)計(jì)沒(méi)有考慮過(guò)電流保護(hù)；微電網(wǎng)仿真研究缺乏系統(tǒng)的控制策略仿真平臺(tái)。針對(duì)上述不足,本文重點(diǎn)針對(duì)光伏電池和SOFC電池這兩種微電源,從分布式微電源建模仿真、單個(gè)分布式微電源并網(wǎng)控制、多個(gè)微電源組成微網(wǎng)后的運(yùn)行控制三個(gè)層面進(jìn)行了相關(guān)技術(shù)的研究,并構(gòu)建了仿真基礎(chǔ)平臺(tái)。主要工作包括： 1、系統(tǒng)地分析并構(gòu)建了三種光伏電池仿真模型,有效實(shí)現(xiàn)對(duì)實(shí)際光伏電池工況的模擬。對(duì)比分析了擾動(dòng)觀察法和增量電導(dǎo)法,優(yōu)選擾動(dòng)觀察法作為光伏電池的MPPT跟蹤方法。構(gòu)建了固體氧化物燃料電池SOFC的中期動(dòng)態(tài)仿真模型,并基于滯環(huán)電流跟蹤控制法實(shí)現(xiàn)SOFC電池的有效輸出。 2、設(shè)計(jì)了光蓄混合發(fā)電系統(tǒng)的結(jié)構(gòu),研究了光蓄混合發(fā)電系統(tǒng)雙向DC/DC變流器的控制策略,經(jīng)過(guò)仿真,驗(yàn)證了所設(shè)計(jì)光蓄混合發(fā)電系統(tǒng)的正確性。 3、研究了三種單微電源控制策略(PQ、V/f和Droop控制策略)的原理,通過(guò)構(gòu)建仿真算例驗(yàn)證了每一種控制策略的有效性。針對(duì)微電網(wǎng)主從控制、對(duì)等控制,設(shè)計(jì)了相應(yīng)的仿真算例,驗(yàn)證了兩種微電網(wǎng)控制方式。 4、在構(gòu)建光伏電池和SOFC電池模型的基礎(chǔ)上,研究了光蓄混合發(fā)電系統(tǒng)控制、SOFC電池并網(wǎng)控制,以及微電網(wǎng)的運(yùn)行與控制策略,從而構(gòu)建了微電網(wǎng)的基礎(chǔ)仿真平臺(tái),為后續(xù)研究工作提供了基礎(chǔ)。
[Abstract]:With the increasing depletion of fossil energy and the continuous development of new energy, distributed power generation, which has strong environmental protection, high flexibility and modularization, has shown a broad development prospects. However, a large number of access to distributed power supply adds a variety of disadvantages to the grid. The emergence of microgrid technology makes the solution of the problem a turnaround. This technology has attracted more and more attention, so it is of great significance to study the technology of distributed generation and microgrid. At present, there are many photovoltaic cell simulation models, but no systematic classification; many optical storage hybrid generation system design did not consider the over-current protection; microgrid simulation research lack of system control strategy simulation platform. In view of the above shortcomings, this paper focuses on photovoltaic cell and SOFC battery, modeling and simulation of distributed micro-power supply, single distributed micro-power source connected to the grid control, Three layers of microgrid operation control are studied, and the basic simulation platform is constructed. The main work is as follows: 1. Three kinds of photovoltaic cell simulation models are analyzed and constructed systematically, which can effectively realize the simulation of the actual photovoltaic cell operating conditions. The perturbation observation method, the incremental conductance method and the optimal perturbation observation method are compared and analyzed as the MPPT tracking method for photovoltaic cells. The medium-term dynamic simulation model of SOFC for solid oxide fuel cell (SOFC) is constructed, and the effective output of SOFC battery is realized based on hysteresis current tracking control method. 2. The structure of hybrid photovoltaic power generation system is designed. The control strategy of the bidirectional DC / DC converter of optical storage hybrid generation system is studied. The correctness of the designed hybrid optical storage power generation system is verified by simulation. 3. The principle of three single micro power supply control strategies (PQ / V / f and Droop control strategy) is studied. The effectiveness of each control strategy is verified by a simulation example. For microgrid master-slave control, peer-to-peer control, a corresponding simulation example is designed to verify the two microgrid control methods. 4. Based on the construction of photovoltaic cell and SOFC cell model, The SOFC battery grid-connected control of optical storage hybrid generation system and the operation and control strategy of micro-grid are studied. The basic simulation platform of micro-grid is constructed, which provides the basis for further research.
