Embodiment Construction

[0033] The present invention will be described below in conjunction with the accompanying drawings and specific examples.

[0034] figure 2 It is the composition of the traditional distribution system. The user's electrical load is supplied by the local power grid and delivered to the user end through the municipal power grid; the cooling load is refrigerated by the electric refrigerator to meet the demand, and the electricity consumed by the electric refrigerator is also supplied by the grid; the gas outlet of the boiler is sent to the user through pipelines.

[0035] The structure of multi-energy complementary comprehensive system is attached figure 1 As shown, this method innovatively proposes to replace the electric refrigerator in the previous triple power supply system with the ground source heat pump to meet part of the cooling load demand of the user, which can greatly reduce the primary energy consumption due to the electric refrigerator in the previous triple power...

Abstract

The invention discloses an optimization method of a multi-energy complementary integrated system, A new optimization method is established with the constraint conditions of the best economy and the least carbon dioxide emission, Equipment composition for the entire integrated system: prime mover, absorption chiller, Heat exchange equipment, gas-fired boilers, photovoltaic power generation and ground-source heat pump systems, which calculate carbon dioxide emission reductions, environmental tax savings, renewable energy green certificates and transaction costs of energy rights for efficient gas-fired energy stations, based on the energy balance between each system and the end user, with the traditional split-supply system as a reference; Preliminary derivation of the optimal economic systemmix interval, and then through the lowest carbon dioxide emissions as a constraint condition for verification, the final selection of environmental protection and economic optimal system capacity allocation. The method realizes the optimization of system configuration according to the environmental protection and high efficiency of the multi-energy complementary integrated system.

Description

technical field [0001] The invention relates to a multi-energy complementary system including natural gas, solar energy and geothermal energy, in particular to a double-constraint optimization method based on the system. Background technique [0002] The integrated energy system is a multi-energy complementary system including natural gas, solar energy, and geothermal energy. It is characterized in that, in areas with more cooling loads than heating loads, the heat emitted to the ground is more than the heat absorbed from the ground, resulting in soil heat imbalance, while buildings The solar energy resource under the cooling condition is more abundant than that under the heating condition. Using this feature just makes up for the shortcoming of soil heat imbalance, which ensures the performance of the ground source heat pump; in areas with more heat load than cooling load, The heat absorbed from the ground is more than the heat discharged to the ground, resulting in soil he...
