Energy Flow Calculation and Integrated Simulation of Micro-energy Grid with Combined Cooling,Heating and Power
摘要
Abstract
Firstly,the concept of micro-energy grid is introduced,and the energy flow model of combined cooling,heating and power(CCHP) system is proposed based on the concept of energy hub.The CCHP will act the role of the coupled nodes between distributed network and natural gas network.Then the finite element node method for the calculation of natural gas network energy flow is deducted.Besides,based on the software of openDSS and MATLAB,a novel method and integrated simulation platform of electricity and gas coupled energy internet is proposed.In order to assess the coupled degree of the distributed network and natural gas network,a novel index named CCHP energy supply rate is introduced.Case studies are taken with two typical operation models on a typical summer day:following the thermal load and following the electric load. Simulation results show that the method and integrated simulation platform are available and the CCHP energy supply rate index can be used to assess the coupled degree of electric-gas energy for micro-energy grid.关键词
