发布时间：2018-10-16 15:26
【摘要】：与传统输电网和配电网络不同,微电网中的分布式发电装置通过电力变换装置给负荷供电,所以考虑并网整流/逆变装置的影响,同时建立包含微电源、柔性交流输电系统、线路以及不同负荷类型的微电网精确数学模型。此外,计及负荷及微电源出力的时间波动性,引入同伦摄动子区间理论构造求解孤岛微电网区间潮流方程,并通过模态分析法提高区间运算精度。算例结果验证了所建模型及求解方法的有效性。
[Abstract]:Compared with the traditional power supply and distribution network, the distributed power generation device in the micro power grid supplies power to the load through the power conversion device, a precise mathematical model of a micro-grid with different load types and different load types. In addition, the time fluctuation of the output of the meter and the load and the output of the micro-power supply is introduced, and the interval flow equation of the isolated island micro-grid is solved by introducing the same-field perturbation subspace theory structure, and the interval calculation precision is improved through the modal analysis method. The result of the calculation verifies the validity of the proposed model and the solution method.
