Abstract

The invention proposes an optimization scheduling method for a large-scale building CCHP (combined cold heat and power supply) system. Through giving comprehensive consideration to the characteristics of a gas turbine, a gas boiler, an absorbing chiller and an electric refrigerating machine according to the characteristics of a cold load, a heat load and an electric load of a building and combining with the operation characteristics of a gas CCHP system, an optimization scheduling model for the large-scale building CCHP system is built, and an improved particle swarm algorithm is used for solving the optimization scheduling model to obtain an optimization scheduling capacity curve of former days, thereby promoting the optimization management of the large-scale building CCHP system. The method achieves the optimization calculation of the former scheduling of the large-scale building CCHP system, and achieves the optimal utilization of energy.

Description

technical field [0001] The invention belongs to the technical field of electric power dispatching, and in particular relates to an optimal dispatching method for a combined cooling, heating and power supply system of a large building. Background technique [0002] With the rapid development of productivity, the problem of energy shortage and environmental pollution has become increasingly prominent. How to improve energy efficiency and environmental protection has become a hot topic. The distributed combined cooling, heating and power system uses clean natural gas as the energy source and has low-emission environmental protection features. In addition, through the step-by-step utilization of energy of different qualities, the utilization efficiency of primary energy can be increased to 90%, which is an effective way to achieve energy efficiency improvement and emission reduction at the same time. [0003] In recent years, with the rapid development of large-scale buildings ...
