面向可再生能源集成的综合能源系统熵态计算模型
Entropy State Calculation Model of Integrated Energy System for Renewable Energy Integration
摘要
Abstract
The entropy state mechanism and analysis method of the integrated energy system(IES)provides a new theoretical basis for the analysis of IES energy quality for renewable energy integration.For different energy system scales and scenarios,how to systematically solve the entropy state distribution of large-scale energy systems is one of the basic problems that need to be solved urgently in subsequent system planning,operation,and energy management and control.On the basis of IES entropy state theory,the calculation system and ideas of the system entropy state distribution are further sorted out.According to the needs of solving the entropy increase flow,some key calculation matrices and calculation column vectors are defined.Then,combined with the definition of IES exergy flow model and entropy state network,considering the entropy increase flow conversion and distribution mechanism of energy hub(energy station),the IES entropy state calculation models based on sequential solution and simultaneous solution are established.The correctness and effectiveness of the two calculation models are verified by cases,and the similarities,differences and applicability of the two calculation methods are discussed.关键词
