【摘要】:可再生能源的大量接入和先進用電技術的不斷推廣使有源配電系統(tǒng)的隨機特性愈發(fā)顯著,這種復雜的隨機擾動會對系統(tǒng)的規(guī)劃、運行和分析計算產生不可忽視的影響。因此,一種準確、高效并且考慮隨機擾動影響的仿真方法對有源配電系統(tǒng)隨機特性的分析研究至關重要。該文通過將確定性投影積分算法和混合隨機數(shù)值積分算法相結合,同時融入滾動式多隨機軌跡仿真思想,提出了一種同時考慮有源配電系統(tǒng)隨機特性和多時間尺度特征的滾動投影積分仿真方法,并以低壓有源配電系統(tǒng)算例為例,通過與確定性仿真和EulerMaruyama算法比較,驗證了文中算法的正確性和有效性。
[Abstract]:With the extensive access of renewable energy and the continuous popularization of advanced power technology, the stochastic characteristics of active power distribution system become more and more obvious. This complex random disturbance will have a significant impact on the planning, operation and analysis of the system. Therefore, an accurate, efficient and stochastic disturbance simulation method is very important to the analysis and study of the stochastic characteristics of active power distribution system. By combining the deterministic projection integral algorithm with the hybrid stochastic numerical integration algorithm, the idea of rolling multi-random trajectory simulation is incorporated in this paper. A rolling projection integral simulation method considering both stochastic and multi-time scale characteristics of active power distribution system is proposed. An example of low-voltage active power distribution system is given and compared with deterministic simulation and EulerMaruyama algorithm. The correctness and validity of the proposed algorithm are verified.
