摘要/Abstract

摘要： 在微电网新能源占比逐渐提高的背景下,针对含电解铝负荷的孤岛微电网系统热电机组调节能力有限、新能源消纳困难的问题,提出面向多时间尺度的光-火-铝孤岛微电网综合能量管理方法。在电解铝负荷参与需求响应的基础上,研究电解铝负荷的调度模型,并基于碳税政策分析孤岛微电网系统中电解铝负荷和热电机组的碳排放模型。最后建立含光伏机组、热电机组和铝电解的孤岛微电网多时间尺度的低碳经济调度模型,以9节点孤岛微电网系统为例进行仿真分析。该方法可以显著提高孤岛微电网系统光伏消纳率,使系统低碳经济运行。

Abstract: Against the background of the gradually increasing proportion of new energy in microgrids, an integrated energy management method for light-fire-aluminum isolated microgrids with multiple time scales is proposed to address the problem of limited regulation capability of thermal power units in isolated microgrid systems containing electrolytic aluminum loads and the difficulty of new energy consumption. On the basis of the participation of the aluminum load in demand response, the dispatch model of the aluminum load is studied, and the carbon emission model of the aluminum load and the thermal unit in the isolated island microgrid system is analyzed based on the carbon tax policy. Finally, a low carbon economic dispatch model of the isolated island microgrid containing photovoltaic unit, thermal unit and electroytic aluminum load at multiple time scales is established. The simulation analysis is carried out with the example of a 9-node isolated island microgrid system to verify that the method can significantly improve the energy consumption of isolated island microgrids. The method can significantly improve the ability of the isolated island microgrid system to consume PV and make the system operate in a low-carbon and economic way.

Key words: electrolytic aluminum load, demand response, isolated microgrid, multi-timescale, low carbon economy
