【摘要】:與傳統(tǒng)輸電網(wǎng)和配電網(wǎng)絡(luò)不同,微電網(wǎng)中的分布式發(fā)電裝置通過電力變換裝置給負(fù)荷供電,所以考慮并網(wǎng)整流/逆變裝置的影響,同時建立包含微電源、柔性交流輸電系統(tǒng)、線路以及不同負(fù)荷類型的微電網(wǎng)精確數(shù)學(xué)模型。此外,計及負(fù)荷及微電源出力的時間波動性,引入同倫攝動子區(qū)間理論構(gòu)造求解孤島微電網(wǎng)區(qū)間潮流方程,并通過模態(tài)分析法提高區(qū)間運算精度。算例結(jié)果驗證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.
