摘要
提出了一个综合考虑光伏发电机组和传统机组的消纳体系,建立了相应的光伏发电消纳分析数学模型,给出了模型求解方法,以标准的IEEE26机24节点系统为原型给出了3个典型算例,并采用GAMS(通用代数建模系统)求解。通过对计算结果的分析,表明光伏机组的加入可明显降低发电成本,且光伏发电需要消耗大量的无功,揭示了综合光伏发电消纳体系中发电成本、机组出力、系统稳定之间的密切联系,从而验证了模型和方法的有效性。
This paper proposes a Power Consumption System with the considerations of photovoltaic power and regular power. A mathematical model for photovoltaic power consumption analysis is built and the way to solve the model is provided. The IEEE 26-generator 24-bus test system is taken as an example and three scenarios of it are analysed with the method of GAMS. The results show that the generation cost is reduced and reactive power consumption is increased with the integration of photovoltaic power. It also reveals that there exists tight connections among generation cost, generation output and power system stability, which validates the effectiveness and correctness of the proposed system.
