Energy-saving optimization method for redundant building combined cooling heat and power (CCHP) system

Abstract

The invention relates to an energy-saving optimization method for a redundant building combined cooling heat and power (CCHP) system, which is used for improving the reliability and energy utilization rate of the CCHP system. The technical scheme is that: the redundant building CCHP system is established by taking the local conventional energy supply system of a building as a reference object, and the capacity and operating strategy of the CCHP system are subjected to optimized allocation by taking comprehensive benefits of energy conservation and reliability as a target, so that the aim of improving energy efficiency and energy supply reliability is fulfilled. The method is simple and convenient, easy to understand and operate, and generally suitable for the optimized design of the common building CCHP system.

Description

technical field [0001] The invention relates to an optimal design method of a building-level combined cooling, heating and power supply system, which can significantly improve the reliability and energy utilization rate of the combined cooling, heating and power supply system, and belongs to the field of energy technology. Background technique [0002] The building-level combined cooling, heating and power system is based on the concept of energy cascade utilization. It takes a building, school or community as a unit and integrates cooling, heating (heating and domestic hot water) and power generation. For total energy system. Its biggest feature is that it is suitable for direct construction in small and medium-sized end users, and it provides users with three products of cooling, heating and power. The efficient operation of a building-level combined cooling, heating and power system is not only related to the structure, equipment composition and capacity of the combined ...

[0005] 2) Reliability assessment and optimization of building-level combined cooling, heating and power generation systems are not involved

At present, the reliability evaluation method of the building-level combined cooling, heating and power system is relatively lacking, and the reliability is not optimized as one of the indicators in the current optimization design, so it is necessary to take the reliability index of the combined generation system into consideration. its optimization

[0006] 3) The operating performance of the building-level combined cooling, heating and power system is closely related to factors such as local energy sources and energy supply methods. The conventional optimization design only considers the optimization of the combined power supply system itself, and does not refer to the local conventional energy supply methods. Integrated and optimized configuration and operation strategy of combined cooling, heating and power generation system
