微電網及微氣網之多能源供應系統 Multi-energy supply system for microgrid and micro gas network

本發明係關於一種微電網及微氣網之多能源供應系統,特別是藉由一微型氣化站氣化產生天然氣與燃料電池發電群組發電所組成之氣、電微網供應多能源之系統。 The invention relates to a multi-energy supply system of a micro-grid and a micro-gas network, in particular to a system for supplying multiple energy sources of gas and electric micro-grids composed of natural gas and fuel cell power generation groups by gasification of a micro gasification station. .

按,天然氣與電力兩種能源為民生不可或缺的主要能源,特別是家家戶戶必需藉由天然氣或電力來作為烹煮食物熱能或洗滌熱水的主要能源,並且,此天然氣與電力兩種能源是目前全世界熱列討論與普遍應用的重要能源之二,然而,習知的天然氣供氣網路與電力供電網路為獨立不相依存之狀態,也就是天然氣由瓦斯公司透過市區地下管線網路供應至用戶端,而電力供電網路由電力公司透過發電廠經由層層輸電幹線與市區地下或地上配電網路供應至電力用戶,而讓此天然氣與電力兩種能源,因供氣網路與供電網路建置、輸配成本昂貴與商業利益考量下,無法普及於如偏遠鄉、鎮或人口稀少之山區或濱海地區等低人口密度及低開發之地區,而僅能依賴有限運輸容量與高運輸成本的桶裝石油氣與自備昂貴的發電機因應,因此,使這些低人口密度及低開發之地區,無法獲得良好的天然氣與電力供應網路延伸建置,而導致這些低人口密度及低開發之地區長久無法被有效開發及產生較好的經濟建設條件,造成能源供應不足或經濟困窘的惡性循環效應,實乃目前極待解決之主要課題。 According to the natural gas and electricity, the two main energy sources are indispensable for the people's livelihood. In particular, every household must use natural gas or electricity as the main energy source for cooking food heat or washing hot water. At present, the world is hotly discussing and sharing the most important energy source. However, the conventional natural gas supply network and the power supply network are independent and independent, that is, natural gas is passed by the gas company through the urban underground pipeline network. The road is supplied to the customer, and the power supply network routing power company supplies the power to the power users through the power transmission line and the urban underground or above-ground distribution network through the power plant, and the natural gas and the electric energy are supplied to the power network. With the construction of power supply networks, the high cost of transmission and distribution, and the consideration of commercial interests, it is not possible to spread to low-density and low-developed areas such as remote townships, towns or sparsely populated mountainous areas or coastal areas, and can only rely on limited transportation capacity. With high transport costs for barreled LPG and self-contained expensive generators, therefore, these low population densities and low development In the region, it is impossible to obtain a good natural gas and power supply network extension, which will result in these low population density and low development areas that cannot be effectively developed and produce better economic construction conditions, resulting in insufficient energy supply or economic embarrassment. The cyclical effect is currently the main issue to be solved.

另外,在習知技術中,雖有以燃料電池作為發電及提供微電網的技術,如中華民國專利公報第I453986號「燃料電池電力控制系統」發明專利案及中華民國專利公報第I482352號「燃料電池供電方法及其燃料電池裝置」發明專利案,則分別揭示以燃料電池作為發電及供電之電力供應系統,藉以提供電力網路作為電力供應來源,但其最主要的發電原始能源, 還是必需依靠天然氣,而如同上述習知天然氣供氣網路與電力供應網路是獨立無關之狀態,而受限於該天然氣的供應網路的建置成本及供輸成本,該燃料電池的供電系統,並無法被使用於上述如偏遠鄉、鎮或人口稀少之山區或濱海地區等低人口密度及低開發之地區,同時,該兩前案充其量也僅能限制在市區或市郊地區供應單一電力能源而已,無法達到如天然氣與電力多能源同時供應的效果。 In addition, in the prior art, there are technologies for generating electricity and providing a microgrid by using a fuel cell, such as the invention patent case of the "Fuel Cell Power Control System" of the Republic of China Patent No. I453986 and the "Technical Publication No. I482352" of the Republic of China. The battery-powered method and its fuel cell device invention patent case respectively disclose a power supply system using a fuel cell as a power generation and power supply, thereby providing a power network as a power supply source, but its main source of power generation, It is still necessary to rely on natural gas, and as the above-mentioned natural gas supply network is independent of the power supply network, and is limited by the construction cost and supply and delivery cost of the natural gas supply network, the fuel cell power supply The system cannot be used in such low-density and low-developed areas as remote townships, towns or sparsely populated mountainous areas or coastal areas. At the same time, the two pre-existing cases can only limit the supply of singles in urban or suburban areas. Only power and energy can not achieve the same effect as the supply of natural gas and electricity.

If there is a sequela of serious environmental pollution and environmental damage caused by leakage, it cannot be provided to Extensive use of industry can only be used in a particular limitation of industrial users, thus significantly the capture of its industrial application areas.

另外,再如中華民國專利公報第M486689號「複合式能源電力供應系統」新型專利案,則揭示如風力發電機、太陽能電池、內燃機發電機等數種天然或燃料發電機的電力能源的整合電力供應系統,但亦僅能提供電力供應網的單一電力能源之提供,無法同時提供如天然氣的另一種能源的供應功能,且該前案中之風力發電機、太陽能電池所能提供之電力供應容量較低,該內燃機發電機同樣需要另外供應燃料以啟動其發電功能,亦存在有燃料運配成本及效率之問題,亦不適合利用於如偏遠鄉、鎮或人口稀少之山區或濱海地區等低人口密度及低開發之地區進行設置利用。 In addition, as in the new patent case of the "Multiple Energy Power Supply System" of the Republic of China Patent Gazette No. M486689, it discloses integrated power of electric energy sources such as wind turbines, solar cells, and internal combustion engine generators. The supply system, but only provides the provision of a single power source for the power supply network, and cannot provide the supply function of another energy source such as natural gas, and the power supply capacity that the wind turbine and solar battery can provide in the previous case. Lower, the internal combustion engine generator also needs to supply additional fuel to start its power generation function. There are also problems with fuel transportation cost and efficiency, and it is not suitable for use in low-income populations such as remote towns, towns or sparsely populated mountainous areas or coastal areas. Set up and use in areas with low density and low development.
