考虑柔性负荷响应策略的有源配电网可靠性分析
摘要：随着大量柔性负荷以及分布式电源的接入，配电网运行可靠性受到多重不确定因素影响。提出了一种考虑柔性负荷响应策略的有源配电网可靠性分析方法。首先，采用伊藤随机过程描述分布式电源出力的时序不确定性。其次，根据柔性负荷特性以及基于一阶随机占优理论的转供容量约束提出柔性负荷滚动响应策略。最后，采用马尔科夫蒙特卡洛法对改进的RTBS6系统进行可靠性分析。算例分析了不同柔性负荷响应策略以及分布式电源接入容量对柔性负荷的出力以及可靠性的影响，为柔性负荷响应提供借鉴。
Abstract:With connecting a lot of flexible loads and distributed generations into distribution network the operation reliability of the latter is affected by multi uncertain factors. For this reason, a method to analyze the reliability of active distribution network considering the response strategy of flexible loads was put forward. Firstly, by use of Ito stochastic process the timing uncertainty of the output of distributed generation was described. Secondly, according to the feature of flexible loads and the constraint of transfer capacity based on the first order stochastic dominance theory a rolling response strategy of flexible load was proposed. Finally, by use of Markov chain and Monte Carlo method the reliability analysis for the improved RTBS6 system was performed. By this computing example, the response strategy of different flexible loads and the impact of switched-in capacity of the distributed generation on the output of flexible loads and reliability were analyzed to provide reference for the analysis on the response of flexible load.
