Abstract

The invention provides a combined cooling heating and electricity supply system based on various-energy-source access. The combined cooling heating and electricity supply system comprises marsh gas, solar energy, geothermal energy, an electricity generating system, a heat exchange system and cooling heating and electricity loads, wherein the marsh gas is directly connected with a direct-fired machine and a micro-gas turbine; the solar energy is sequentially connected with photovoltaic electricity generation equipment and the electricity grid cooling heating and electricity loads; and the geothermal energy is connected with an electricity generator and a heat exchanger. The combined cooling heating and electricity supply system based on various-energy-source access provided by the invention has the advantages that the integral utilization of the marsh gas, the solar energy and the geothermal energy can be realized by combining the region characteristics; the energy source integral utilization efficiency is improved; and the integral benefits of an electric power system are increased.

Description

technical field [0001] The invention belongs to the field of combined cooling, heating and power supply systems, and in particular relates to a combined cooling, heating and power supply system based on the access of multiple energy sources. Background technique [0002] Energy is the material basis for human survival and the driving force for economic development. Because of this, in today's world, while the economy is developing rapidly, non-renewable energy sources such as coal and oil are also facing depletion. The traditional power industry is dominated by thermal power generation, which consumes a large amount of coal resources and also causes serious environmental pollution. The pressure on resources and the environment has brought new challenges to the power system. The use of new energy to gradually replace traditional energy for power generation will It is the development trend of the electric power industry in the future. Distributed energy system is a kind of co...
