摘要
燃气轮机、燃气锅炉以及热电联产系统等耦合单元的广泛应用使电力系统、天然气系统和热力系统之间的联系日益紧密,而各网运行主体不同导致的可交互信息有限,又给全网潮流分布的计算带来挑战。该文模型计及热电联产系统、燃气轮机、燃气锅炉、压缩机、水泵等多种耦合单元,并重点考虑耦合单元位于电网、热网平衡节点的影响,提出在各网之间有限信息交互下的不同运行模式的潮流分布式顺序求解算法。通过对实际算例的求解,证明所提算法比牛顿–拉夫逊统一求解算法在收敛速度、精度方面更有优势。
The wide application of coupling units,such as gas-fired generators,gas-fired boilers and combined heat and powers(CHPs),make an increasing connection between electrical,natural gas and heating system.However,limited communication,resulting from operators'difference,between each network,brings the challenge to energy flow calculation of unified system.The model in this paper studiedthe influence of coupling units including CHPs,gas-fired generators, gas-fired boilers,compressors and pumps,especially when they are located in the slack node of electrical or heating network. And distributed sequential algorithms of different operating modes were proposed for energy flow calculation with limited communication.Taking real system for example,the proposed methodhasadvantageofspeed-andaccuracy,over Newton-Raphson.unified method.
