基于交易联络线的TCPAR的AGC频率调节过程研究

AGC frequency regulation with TCPAR under tie-line power change

以双边交易作为市场环境下AGC的交易模式,发电和配电公司可以自由签订合同,也可以跨区域签订用电合同,通过配电参与矩阵模拟了配电公司与发电公司之间的合同规定。在此背景下,将TCPAR(晶闸管控制相角调节器)安装在联络线上,参与到AGC调节过程中,建立了考虑和不考虑TCPAR的AGC动态模型,分析结果表明,TCPAR有助于抑制由于电力系统扰动引起的频率和联络线功率的大幅度波动,从而改善电力系统运行状态,提高系统稳定性。

This paper takes into account bilateral contracts as the exchange mode under power market. Thus, GENCOs and DISCOs have liberty for contracts, even they may have contracts across their area. The concept of DISCO participation matrix is used to model the contracts between the GENCOs and DISCOs. In this background, TCPAR is installed on the tie-line, joining in the AGC regulation. AGC dynamic models are established without and with TCPAR, simulation results show that TCPAR can introduce good damping of frequency and tie-line power flow oscillations due to the disturbance of power system, and promote the operation condition as well as the stability of the system.
