An Improved IES Calculation Method for Multi-energy Flow Including Cold,Heat,Electricity and Gas
摘要
Abstract
In order to solve the problem that various energy sources in the traditional energy system are not tightly coupled,different energy sources are relatively independent,and the overall energy utilisation rate is not high,the integrated smart energy platform has become a problem that must be considered.Combine the integration of the Internet and energy to develop into an energy Internet,making energy"smart"is a brand-new energy management model.Therefore,the power flow calculation under the integrated energy system(IES)has become the focus and difficulty.This paper proposes an IES improved multi-energy flow calculation method,which is suitable for cold,heat,electricity,and gas.This paper firstly establishes the mathematical models of power,heat,and natural gas networks in IES.Secondly,based on the steady-state energy flow model of the natural gas system,a linearized model of the natural gas pipeline flow equation is constructed based on the piecewise linearization method;Based on this,an optimization model of the initial value of the natural gas system is established to obtain a good initial value.The linearized pipeline flow equation is used in the model to simplify the complexity of the model.Finally,the improved Newton-Raphson method is used to derive and obtain the Jacobian matrix reflecting the coupling relationship of multiple energy sources.The calculation example verifies the effectiveness of the method for calculating and analyzing the interaction characteristics of multi-energy flow.关键词
