Comprehensive energy source router equipment and energy source conversion method

Abstract

The invention provides comprehensive energy source router equipment and an energy source conversion method. The equipment comprises a mini-type gas turbine engine, a residual heat power generation device, a power storage device, a heat storage device and the like, wherein the residual heat power generation device is used for absorbing residual heat in high-temperature flue gas obtained by combustion of the mini-type gas turbine engine and carrying out an organic Rankine cycle; and the energy source conversion method comprises a mode of fixing power based on heat, a mode of fixing heat based onpower and an automatic power and heat adjusting mode. Therefore, the invention provides the comprehensive energy source router equipment which contains solar power generation, wind power generation,energy storage and organic Rankine cycle systems and a traditional combined cold, heat and power supply system; energy sources can be mutually interconnected and transformed through a comprehensive energy source coupling model, so that electric energy and heat energy can be very flexibly distributed; three optimization targets of economic cost, energy source consumption and pollution emission areestablished; and compared with a traditional energy source network, the equipment provided by the invention can be used for greatly increasing the comprehensive utilization efficiency of energy sources and reducing the emission of pollutants, so that the economic benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to an integrated energy router device and an energy conversion method. Background technique [0002] At present, the electricity, heating and natural gas required by the demand side are supplied separately from each other. The electricity is supplied by the grid system, the heating is supplied centrally by the community, and the natural gas is directly provided to users by the gas network. In order to better adapt to the access form of distributed power generation and increase the consumption rate of renewable energy power generation, the power supply has begun to develop in the direction of community-level micro-grids, and the scope of power supply and community heating gradually overlap. The combined cooling, heating and power system with gas internal combustion engine or gas turbine as the core recycles the high-temperature air generated after combustio...

Problems solved by technology

Although the combined cooling, heating and power system has been put into use at present, the bundled production of heat and electricity makes it difficult to flexibly allocate power generation and heat production.
