【摘要】:長期以來,海島居民用電保障都十分困難,大陸遠(yuǎn)距離送油發(fā)電是目前解決海島供電問題的主要途徑。但這種方式成本高,且易受外界因素制約。因此,依靠海島自身?xiàng)l件來解決能源保障才是根本。近年來,隨著國家發(fā)展戰(zhàn)略轉(zhuǎn)型以及可再生能源開發(fā)利用的優(yōu)勢日益突出,各種可再生能源的開發(fā)與利用規(guī)?涨昂甏。太陽能無處不在,無論陸地、海洋或島嶼,更為寶貴的是它是最清潔的能源之一。因此太陽能光伏發(fā)電技術(shù)將成為解決海島供電問題的有效方式。本文以海島戶用建筑為背景,對(duì)獨(dú)立光伏供電系統(tǒng)的能量控制系統(tǒng)的控制策略及容量設(shè)計(jì)部分的關(guān)鍵問題展開研究,并進(jìn)行經(jīng)濟(jì)和環(huán)境評(píng)價(jià)。 本文介紹了光伏應(yīng)用的背景及特點(diǎn),對(duì)光伏發(fā)電系統(tǒng)進(jìn)行簡要概述,指出課題研究的意義和主要內(nèi)容。 構(gòu)建戶用直流母線式結(jié)構(gòu)的獨(dú)立光伏發(fā)電系統(tǒng),對(duì)能量控制策略進(jìn)行研究,包括采用改進(jìn)的變步長擾動(dòng)占空比的最大功率點(diǎn)跟蹤控制策略來提高系統(tǒng)對(duì)太陽能的利用率;提出一種考慮最大功率點(diǎn)跟蹤的蓄電池充電控制策略,保證直流母線電壓的穩(wěn)定;詳細(xì)分析系統(tǒng)的工作模式,給出系統(tǒng)能量協(xié)調(diào)控制策略,實(shí)現(xiàn)各環(huán)節(jié)的穩(wěn)定運(yùn)行,并分別進(jìn)行仿真驗(yàn)證。 依據(jù)?诘貐^(qū)氣象數(shù)據(jù)模擬海島,,分析典型家庭的用電需求,研究系統(tǒng)的容量計(jì)算方法,給出系統(tǒng)的容量配置方案;依據(jù)系統(tǒng)的成本及成本回收期限給出經(jīng)濟(jì)評(píng)價(jià),并對(duì)系統(tǒng)的CO2減排量及光伏系統(tǒng)減排CO2潛力兩個(gè)指標(biāo)給出環(huán)境評(píng)價(jià)。
[Abstract]:For a long time, it has been very difficult for island residents to use electricity, and long-distance oil and power generation in mainland is the main way to solve the problem of island power supply at present, but this way is expensive and easy to be restricted by external factors. In recent years, with the transformation of national development strategy and the advantages of renewable energy development and utilization, it is essential to rely on the island's own conditions to solve the problem of energy security. The development and utilization of all kinds of renewable energy is unprecedented. Solar energy is everywhere, whether on land, sea or island. More precious is that it is one of the cleanest energy, so solar photovoltaic power generation technology will become an effective way to solve the problem of power supply in islands. The key problems of the control strategy and capacity design of the energy control system of the independent photovoltaic power supply system are studied, and the economic and environmental evaluation are carried out. This paper introduces the background and characteristics of photovoltaic application, summarizes the photovoltaic power generation system, and points out the significance and main contents of the research. An independent photovoltaic power generation system with DC bus structure is constructed, and the energy control strategy is studied. The improved maximum power point tracking control strategy with variable step-size disturbance duty cycle is used to improve the utilization rate of solar energy. A charging control strategy considering maximum power point tracking is proposed to ensure the stability of DC bus voltage. The working mode of the system is analyzed in detail, and the coordinated control strategy of system energy is given to realize the stable operation of each link, and the simulation is carried out respectively. According to the meteorological data of Haikou area, this paper simulates the island, analyzes the electricity demand of typical families, studies the capacity calculation method of the system, and gives the system capacity configuration scheme. The economic evaluation is given according to the cost and cost recovery period of the system, and the environmental evaluation is given for the CO2 emission reduction of the system and the potential of the photovoltaic system to reduce the CO2 emissions.
