Problems solved by technology
[0002] With the acceleration of industrialization and urbanization, Chinese residents have more and more demand for heat supply. Conventional heat sources for central heating are generally coal-fired power plants or gas-fired power plants, which pass high-temperature and high-pressure steam (or hot water) through pipelines. After being transported to the heat exchange station, the hot water generated is sent to the terminal for heating. This heating method has high carbon emissions and requires the construction of a large number of high-temperature and high-pressure equipment, which requires a large investment.

The invention discloses a regional comprehensive energy heat supply system and method based on multi-energy complementation. The regional comprehensive energy heat supply system comprises at least twoof a photo-thermal system, a heat pump system, an electric boiler, a gas-fired boiler and a gas triple co-generation system; the photo-thermal system is used for generating hot water to supply heat to users; the heat pump system and the electric boiler are used for being connected with an external power grid and generating hot water to supply heat to users; and the gas-fired boiler and the gas triple co-generation system are connected with a natural gas pipeline and used for generating hot water to supply heat to users. The regional comprehensive energy heat supply system meets the heat supply demand of regional users on the basis of coordination and multi-energy complementation of heat supply sources such as natural gas, electric power and photovoltaics.
Description
technical field [0001] The invention belongs to the technical field of heating, and in particular relates to a regional comprehensive energy heating system and a heating method based on multi-energy complementarity. Background technique [0002] With the acceleration of industrialization and urbanization, Chinese residents have more and more demand for heat supply. Conventional heat sources for central heating are generally coal-fired power plants or gas-fired power plants, which pass high-temperature and high-pressure steam (or hot water) through pipelines. After being transported to the heat exchange station, hot water is generated and sent to the terminal for heating. This heating method has high carbon emissions and requires the construction of a large number of high-temperature and high-pressure equipment, which requires a large investment. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a regi...
