【摘要】：可再生能源的大量接入和先进用电技术的不断推广使有源配电系统的随机特性愈发显著,这种复杂的随机扰动会对系统的规划、运行和分析计算产生不可忽视的影响。因此,一种准确、高效并且考虑随机扰动影响的仿真方法对有源配电系统随机特性的分析研究至关重要。该文通过将确定性投影积分算法和混合随机数值积分算法相结合,同时融入滚动式多随机轨迹仿真思想,提出了一种同时考虑有源配电系统随机特性和多时间尺度特征的滚动投影积分仿真方法,并以低压有源配电系统算例为例,通过与确定性仿真和EulerMaruyama算法比较,验证了文中算法的正确性和有效性。
[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.
