分布式电源参与下的配电侧无功补偿纳什议价模型

Nash bargaining model of reactive power compensation on the distribution side with the participation of DG

随着配电网中分布式电源(distributed generation,简称DG)渗透率的不断提高,研究DG参与下的配电侧无功补偿,对维持电压稳定具有现实意义.提出分布式电源参与下的配电侧无功补偿纳什议价模型,对无功补偿带来的额外效益进行合理分配.以IEEE33节点系统为算例,对所提模型进行仿真验证,结果表明:该模型能够有效激励DG参与无功补偿,在提升分布式电源运营商和配电网运营商效益的同时,能提高电能质量.

With the continuous improvement of distributed generation(DG)permeability in distribution network,research on distribution side reactive power compensation with DG participation has the practical significance for maintaining voltage stability.A Nash bargaining model of reactive power compensation on distribution side with distributed power supply was proposed to reasonably distribute the extra benefits brought by reactive power compensation.Taking IEEE33 node system as an example,the proposed model was simulated and verified.The results showed that the model could effectively motivate the distributed generation to participate in reactive power compensation,improve the efficiency of distributed power supply operators and distribution network operators,and improve the power quality.
