Embodiment Construction
[0034] Best practice:
[0035] The optimization method described in the present invention is oriented to the energy-consuming areas of multiple terminal energy demands of electricity, heat, and cooling, based on the lowest environmental emissions (both environmental gains and losses are converted to economically comparable prices, and the lowest environmental emissions are taken under the premise of a certain guarantee of overall economic benefits) Optimum), the best economic utilization of heat exergy these two constraints, carry out comprehensive energy supply system configuration. Focusing on the clean and high-efficiency characteristics of the integrated energy system, the environmental emission index system comprehensively considers its saved greenhouse gas emissions, environmental tax fees, green energy certificates, energy use right trading income fees, and thermal energy economic utilization rate. The pressure, temperature and energy quality indicators of the heat medi...

The invention relates to a comprehensive energy system of electric, cold and thermal multi-terminal requirements, and particularly to a comprehensive-energy-system optimization method based on doubleconstraint conditions of optimal environment emission and thermal-exergy utilization. The method is based on constituent elements of a cold, thermal electric triple-supply system of fired gas, a fired-gas boiler, an electric refrigerator and a photovoltaic+energy storing system of the comprehensive energy system, all types of market values of greenhouse-gas (carbon) emission, benefits of environment tax saving, a green certificate of renewable energy and energy use right of a highly efficient fired-gas energy station are all standardized as comparable prices through a carbon emission accounting method based on terminal consumption and other methods according to all the elements of the system; and a system ratio interval of optimal thermal-exergy utilization is obtained by initial derivation, and then ratio composition of all subsystems of the comprehensive energy system corresponding to a smallest total amount of greenhouse-gas and pollutant emission is finally selected through simulation, measurement, calculation and verification on total amounts of greenhouse-gas and pollutant discharge. The method has the advantage of realizing system matching degree optimization for features ofcleanness and high efficiency of the comprehensive energy system.
Description
technical field [0001] The invention relates to an integrated energy system oriented to multi-terminal demands of electricity, cooling, and heat, in particular to an optimization method for an integrated energy system based on the optimal dual constraint conditions of environmental emission and heat exergy utilization. Background technique [0002] An integrated energy system is an energy-using system that is oriented to multiple terminal energy demands of electricity, cooling, and heating. At present, energy system planning and design methods are mostly independent of each other, that is, energy systems such as electricity, heating, cooling, and energy storage are planned independently. Design, the overall energy utilization efficiency is low after system integration. In the prior art, there are various evaluation methods for the comprehensive energy system, mainly by converting multiple factors or evaluation indicators of the energy system into comprehensive indicators tha...
