Economic dispatch of power and natural gas coupling system considering comprehensive demand response

为解决电力天然气耦合系统波动问题,计及需求响应在耦合系统中的影响,提出了基于需求响应的耦合系统经济调度。分析了天然气电力耦合系统的基本组成和能量流动,建立了电力天然气联合系统的优化调度模型,模型中考虑需求响应约束,同时分别考虑天然气系统约束中的常规约束和压缩机约束,提出电力天然气系统在含有需求响应时的可行域,利用仿真分析说明需求响应在削减成本、电力负荷优化方面的作用。

In order to solve the problem of random power sources in the trading mechanism of electricity and natural gas markets,a coupled market model considering random power sources is proposed.The dual market transaction price of electricity and natural gas is proposed,and the market clearing mechanism is designed,which is classified according to the coupling relationship between electricity and natural gas markets.The natural gas flow constraints and natural gas storage constraints are analyzed.According to the three established clearing models,different optimization models of power and natural gas systems are proposed.The simulation analysis of the proposed model verifies the rationality of the model is proposed.
