摘要
交直流混合微电网中的分布式电源具有典型的功率波动特性,微电网的经济性和可靠性会因此受到严重的影响。针对交直流混合微电网调控困难的现状,在分析柔性负荷功率特性的基础上,提出一种计及柔性负荷的交直流混合微电网控制模型,将负荷端功率控制与传统的电源侧功率控制相结合,交流子网与直流子网的双向功率传输则采用柔性双下垂控制策略。建立交直流混合微电网仿真计算模型,通过不同控制策略和不同柔性负荷下的微电网经济可靠性对比分析,结果验证了所提控制策略的优越性及柔性负荷在微电网控制的价值。
The distributed power supply in AC/DC hybrid microgrid has typical power fluctuation characteristics,and the economy and reliability of microgrids will be seriously affected.Aimed at the difficulty of AC/DC hybrid microgrid power regulation,based on the analysis of the power characteristics of flexible load,a control model of AC/DC hybrid microgrid with flexible load is proposed in this paper.Combined the load-side power control with traditional power-side power control,the bidirectional power transmission between AC and DC subnets is controlled by flexible double droop.The simulation and calculation model of AC/DC hybrid microgrid is established,and the superiority of the proposed control strategy and the value of flexible load control in microgrid in this paper are verified from the results.
