摘要
为增强各能源间的联系,进一步提高终端用户的能源利用率,最大程度地促进可再生能源的就地消纳,建立了交直流混合微电网多能互补优化运行数学模型。该模型以经济成本最低为目标,嵌入冷热电联供(CCHP)系统,在满足用户对冷热电负荷需求的基础上,进一步提高运行效率和降低运行成本。最后,基于实际工程数据进行模型验证,并将结果与传统微电网系统进行对比,验证了所提出的优化模型和方法的合理性与有效性。
To strengthen the relationship between the energies,this paper established a mathematical model for optimal scheduling of AC-DC hybrid micro-grid＇s complemented multiple energy sources,which can further increase the energy utilization rate and promote renewable energy consumption. This model is aimed at the lowest economic cost,and it is embedded into the combined cooling heating and power（ CCHP） system. On the basis of satisfying the user＇s demand for the cold and hot power load,the operating efficiency is further improved and the operating cost is reduced. Finally,the model validation was carried out based on the actual engineering data,and the results are compared with the traditional micro-grid system to verify the rationality and effectiveness of the proposed optimization model and method.
