Study Of Gas Turbine Distributed Energy System Assisted By Solar Energy

The arrival of the energy Internet makes the development of energy system more reasonable and integrity.There are some drawbacks in the traditional energy structure,the use of large quantities of fossil energy not only inefficient,but also poor environmental performance,which is not in line with the policy of sustainable development.The development and utilization of renewable energy is the trend of energy development in the future.In the new era of energy internet,distributed energy system occupies an important position,and mult i-energy complementary distributed energy supply system is a research hotspot at home and abroad.Firstly,the trough solar collector system is integrated with the gas turbine system,and the gas turbine solar energy subsystem is established.The high temperature flue gas of gas turbine is introduced into the absorption refrigeratio n to produce cold or heat,finally,the exhaust gas of the refrigeration is used to produce domestic hot water through heat exchanger.Through the establishment of such a distributed energy system with complementary solar energy and natural gas,then the system is subjected to thermal performance analysis and economic analysis.Thermodynamic performance analysis of the system is carried out from the viewpoint of energy balance and exergy balance respectively.The thermal performance of the system is studied by changing the important parameters such as the heat collection area,the maximum cycle temperature of the gas turbine and the solar radiation intensity.Through the establishment of a cost allocation model based on energy level for the system,the cost analysis and calculation of multi-product exergy of the system are carried out.The cost loss of each equipment in the system is analyzed from the perspective of exergy.Finally,the sensitivity analysis of the main parameters affecting the cost of exergy is carried out.
