Abstract:

The multi-energy complementary distributed integrated energy supply system, which is typical of green, low carbon and high efficiency, has become the research focus in the energy sector at home and abroad. The basic concept, main technical characteristics, main components and key technologies of multi-energy complementary distributed integrated energy supply system were described. In addition, based on the energy supply needs and energy endowment of a typical science and technology innovation park in China, the comprehensive energy scheme of 'Integration of Five Aspects' was researched. The main energy supply system of this scheme includes gas distributed energy, distributed photovoltaic, distributed wind power, the sewage-source heat pump and energy storage, and the energy networks include electric power, heating power, refrigerant water, natural gas and reclaimed water. With intelligent technology, this scheme may achieve the 'source-network-load' system optimal operation and meet the different demand of energy consumers. Finally, some suggestions were given for the development and existing problems of China's multi-energy complementary distributed integrated energy supply system.

Key words: multi-energy complementation, distributed energy, integrated energy supply system, typical development scheme, development suggestion
