【摘要】：分布式能源系統(tǒng)是集節(jié)能、經(jīng)濟(jì)、環(huán)保、可靠等諸多優(yōu)勢于一體的新型供能模式,在我國有著廣泛發(fā)展前景。如何對分布式能源系統(tǒng)進(jìn)行運(yùn)行模擬及其合理有效評價,是發(fā)展分布式能源面臨的重大問題。本文根據(jù)上海市典型年氣候參數(shù),結(jié)合建筑設(shè)計規(guī)范及建筑物使用規(guī)律,利用e QUEST軟件對辦公樓、賓館和住宅三種建筑進(jìn)行了全年逐時負(fù)荷模擬;并針對住宅和辦公樓、住宅和賓館組成的兩類混合建筑,分析了其負(fù)荷特性。在負(fù)荷模擬的基礎(chǔ)上,以滿足逐時冷熱電負(fù)荷為邊界條件,基于TRNSYS軟件,分別建立了分布式能源系統(tǒng)“以熱定電”和“以電定熱”兩種運(yùn)行模式的模擬框架,針對不同類型建筑進(jìn)行模擬分析。根據(jù)模擬分析結(jié)果,可得出以下結(jié)論:(1)在現(xiàn)行價格機(jī)制和分布式能源“并網(wǎng)上網(wǎng)”運(yùn)營模式下,針對單一建筑和混合建筑,無論采用“以熱定電”還是“以電定熱”運(yùn)行模式,分布式能源系統(tǒng)的經(jīng)濟(jì)性、節(jié)能性和環(huán)境性都要優(yōu)于熱電分供系統(tǒng);而且“以熱定電”模式的經(jīng)濟(jì)性、節(jié)能性和環(huán)境性均優(yōu)于“以電定熱”模式。(2)無論采用“以熱定電”還是“以電定熱”運(yùn)行模式,混合建筑分布式能源系統(tǒng)的經(jīng)濟(jì)性優(yōu)勢明顯;在“以電定熱”運(yùn)行模式下,其節(jié)能性有一定優(yōu)勢。(3)在“以熱定電”運(yùn)行模式下,分布式能源系統(tǒng)節(jié)能性與熱電比成正比,經(jīng)濟(jì)性隨著上網(wǎng)電價的提高、用氣價格的降低而不斷提升。以賓館建筑為例,熱電比小于1.13時,才能體現(xiàn)分布式能源系統(tǒng)的節(jié)能性;上網(wǎng)電價大于0.46元/k Wh、分布式能源用氣價格低于3.21元/m3時,建設(shè)和運(yùn)營分布式能源系統(tǒng)才有現(xiàn)實意義。
[Abstract]:Distributed energy system is a new energy supply mode which integrates many advantages, such as energy saving, economy, environmental protection, reliability and so on. There is a broad development prospect in China. How to simulate the operation of distributed energy system and how to evaluate it reasonably and effectively is an important problem in the development of distributed energy. This paper is based on the typical annual climate parameters of Shanghai. Combined with building design code and building usage rule, the hourly load simulation of office building, guesthouse and residential building is carried out by using e QUEST software. The load characteristics of two kinds of mixed buildings composed of residential building and office building, residential building and guesthouse are analyzed. On the basis of load simulation, the boundary condition is to satisfy the hourly cooling and heating load. Based on the TRNSYS software, the simulation framework of the distributed energy system is established, which is based on the two operation modes of "heating by heating" and "heating by electricity". According to the results of simulation analysis, we can draw the following conclusions: 1) under the current price mechanism and distributed energy "connected to the Internet" operation mode. For single building and mixed building, the economy, energy saving and environmental property of distributed energy system are superior to those of thermal power distribution system, regardless of the operation mode of "heat and electricity fixed" or "electric heating". Moreover, the economy, energy saving and environmental property of the mode of "fixing electricity by heat" are better than that of mode of "fixing electricity by electricity" or "fixing heat by electricity" whether it adopts the operation mode of "fixing electricity by heat" or "fixing heat by electricity". The economic advantages of distributed energy system in hybrid buildings are obvious. Under the operation mode of "fixed heat by electricity", its energy-saving property has a certain advantage. Under the operation mode of "fixing power by heat", the energy saving performance of distributed energy system is directly proportional to the ratio of heat and power, and the economy is increasing with the increase of electricity price on the Internet. Taking hotel buildings as an example, the ratio of heat to power is less than 1.13, which can reflect the energy saving of distributed energy system. Only when the electricity price is greater than 0.46 yuan / k / what and the gas price of distributed energy is less than 3.21 yuan / m3, will it be of practical significance to build and operate the distributed energy system.
