摘要

电转气(P2G)技术实现了电力与天然气之间能量的双向流动

为多能源系统协同消纳弃风提供了新途径。本文研究了P2G设备的技术原理

建立了P2G的数学模型

分析了其消纳弃风原理

并在提出其启停策略的基础上

建立了具有电转气功能的多能源系统协同优化调度模型。对比分析了燃气-蒸汽联合循环机组加P2G和常规热电机组加电锅炉2种组合方案的消纳弃风效果。研究表明:P2G和电锅炉都有利于风电消纳

但P2G的消纳弃风效果不如电锅炉

而燃气-蒸汽联合循环机组加P2G组合方案的消纳弃风效果更佳。

Abstract

The power-to-gas(P2 G) technology realizes bidirectional flow of energy between electricity and natural gas

and provides a new way for waste wind power accommodation in multi-energy systems. The technical principle of the P2 G system equipment is studied

the mathematical model of the P2 G system is established

and the principle of waste wind power accommodation is analyzed. On the basis of putting forward start-stop strategy of the P2 G

a cooperative optimal dispatching model of multi-energy system with P2 G conversion function is established. Moreover

the waste wind power accommodation effect of two combination schemes

the gas-steam combined cycle unit combined with the P2 G and the conventional thermoelectric unit combined electric boiler

are compared. The result shows that

both the P2 G and electric boiler are beneficial to waste wind power accomodation

but the consumption effect of the P2 G is weaker than that of the electric boiler. However

the scheme of gas-steam combined cycle unit combined with the P2 G has better effect.
