【摘要】：分布式太陽(yáng)能光伏發(fā)電是最適宜與城市構(gòu)筑物相結(jié)合的可再生能源利用方式,然而在城市中實(shí)際應(yīng)用并不廣泛。主要原因有:既有城市規(guī)劃、建筑設(shè)計(jì)未對(duì)光伏發(fā)電利用加以足夠的考慮;受到建成條件限制,光伏設(shè)備可集成面積零碎而分散。對(duì)于采用眾多零散、分散的面積集成的分布式光伏發(fā)電系統(tǒng),如采用傳統(tǒng)的DC/AC逆變并網(wǎng)方式,逆變輸入端的電流電壓不穩(wěn)定,造成并網(wǎng)輸電過(guò)程中電能損耗大,導(dǎo)致光伏發(fā)電系統(tǒng)利用效率降低。為提高城市光伏利用率,解決城市住區(qū)光伏發(fā)電集成與電能利用問(wèn)題,本研究創(chuàng)新性在城市住區(qū)中應(yīng)用光伏直流微電網(wǎng)系統(tǒng),構(gòu)建了光伏直流微電網(wǎng)在城市住區(qū)應(yīng)用的理論基礎(chǔ),并就應(yīng)用光伏直流微電網(wǎng)系統(tǒng)的住區(qū)規(guī)劃設(shè)計(jì)的方法進(jìn)行了梳理,同時(shí),為方便規(guī)劃師、建筑師能在短時(shí)間內(nèi)快速預(yù)測(cè)光伏發(fā)電量并在城市住區(qū)規(guī)劃設(shè)計(jì)階段最大化利用光伏發(fā)電,提出了一種住區(qū)光伏一體化設(shè)計(jì)與快速預(yù)測(cè)光伏發(fā)電量的方法。本研究提出的光伏直流微電網(wǎng)系統(tǒng)集成設(shè)置在城市住區(qū)建筑、公共便民設(shè)施、道路等零碎、分散面積上的太陽(yáng)能光伏設(shè)備,利用直流微電網(wǎng)技術(shù)優(yōu)勢(shì),為住區(qū)住戶及與物業(yè)的直流用電設(shè)備供應(yīng)直流電能。在保證太陽(yáng)能光伏發(fā)電系統(tǒng)高效運(yùn)行同時(shí),實(shí)現(xiàn)住區(qū)內(nèi)光伏發(fā)電的“就地發(fā)電、就地消納”。通過(guò)對(duì)南寧市五象新區(qū)某住區(qū)為案例進(jìn)行應(yīng)用分析研究,驗(yàn)證了住區(qū)光伏直流微電網(wǎng)系統(tǒng)技術(shù)上可行,并與傳統(tǒng)并網(wǎng)分布式光伏發(fā)電系統(tǒng)相比,不僅降低了初始投資等經(jīng)濟(jì)投入,節(jié)能減排效益顯著,而且供電可靠性也有極大提升。
[Abstract]:Distributed solar photovoltaic power generation is the most suitable renewable energy utilization mode combined with urban structures. However, it is not widely used in cities. The main reasons are as follows: not enough consideration is given to the utilization of photovoltaic power generation in both urban planning and architectural design, and the integrated area of photovoltaic equipment can be scattered and fragmented due to the limitations of the conditions of construction. For the distributed photovoltaic power generation system with many scattered and scattered area integration, such as the traditional DC/AC inverter grid-connected mode, the current and voltage of the inverter input terminal are unstable, resulting in a large power consumption in the process of grid-connected transmission. As a result, the utilization efficiency of photovoltaic power generation system is reduced. In order to improve the utilization rate of photovoltaic and solve the problems of photovoltaic power integration and power utilization in urban residential area, this paper innovates the application of photovoltaic DC microgrid system in urban residential area. The theoretical basis of the application of photovoltaic DC microgrid in urban residential area is constructed, and the planning and design method of residential area using photovoltaic DC microgrid system is combed out. At the same time, for the convenience of planners, The architect can quickly predict photovoltaic power generation in a short period of time and maximize the use of photovoltaic power generation in urban residential area planning and design stage. A method of integrated design and rapid prediction of photovoltaic power generation in residential area is proposed. In this study, the PV DC microgrid system integrated in urban residential buildings, public facilities, roads and other fragmented, scattered area of solar photovoltaic equipment, using DC microgrid technology advantages, Direct current power supply for residential residents and DC equipment with property. In order to ensure the efficient operation of solar photovoltaic power generation system, we can realize the "local generation, local absorption" of photovoltaic power generation in the residential area. A case study of a residential district in Wuxiang New District of Nanning City shows that the photovoltaic microgrid system in residential area is technically feasible and compared with the traditional grid-connected distributed photovoltaic power generation system. Not only the economic investment such as initial investment is reduced, the benefit of energy saving and emission reduction is remarkable, but also the reliability of power supply is greatly improved.
