Mixed integer nonlinear model optimization method for region distributed type cooling, heating and power poly-generation system

Abstract

The invention provides a mixed integer nonlinear model optimization method for a region distributed type cooling, heating and power poly-generation system. A distributed energy supply system is designed and optimized according to regional load characteristics, and the guidance is provided for the overall planning of a regional integrated energy system. Through the feedback on the operating state of a model optimized output, the envelop enclosure of an existing building is transformed definitively and exemplarily, so that the load level of a system balance object is reduced. According to the technical scheme of the invention, according to chronological load characteristics, the technology components and the technology parameters of the system are designed, and a production running scene of the poly-generation system is set. Meanwhile, the running state and the running parameters of the CCHP poly-generation system within each hour during the full production period can be accurately simulated and optimized in real time under the consideration of comprehensive benefits. Therefore, a reasonable solution is provided for the design and the optimization of the region distributed type cooling, heating and power poly-generation system, wherein the advantages of economy, environmental protection, energy conservation and the like are simultaneously realized.

Description

technical field [0001] The invention relates to the technical field of combined cooling, heating and power generation systems, in particular to an optimization method for a mixed integer nonlinear model of a regional distributed combined cooling, heating and power generation system. Background technique [0002] The drawbacks of the energy supply mode of "large units, high voltage, and large power grid" are becoming increasingly apparent, and energy consumption and environmental crisis have become issues that cannot be ignored in social development. Adhering to traditional energy utilization methods cannot effectively recycle resources, which will aggravate the deterioration of the entire resource environment of society and cause rapid depletion of energy. Therefore, with the government’s liquefied natural gas incentive policy and the advocacy of energy conservation and emission reduction indicators, the integrated cascaded energy system—Combined cooling, heating and power (...

Problems solved by technology

The optimization algorithm abstracts a mathematical model that conforms to certain laws by simulating natural phenomena, and provides an important technical method for solving complex engineering practices. However, the nature of its random search determines its slow calculation speed.
