摘要
离网型微网凭借独立、自治运行等特点,可有效保证网内负荷的正常供电。首先建立风电机组的时序出力模型,然后针对不同的储能运行策略,建立储能系统充放电模型;在传统时序蒙特卡洛算法的基础上,提出基于微网随机、时序等运行特性的可靠性评估算法,并对改进的RBTS Bus 6孤岛系统进行可靠性评估。算例分析表明,该算法能有效地计算离网型微网系统的可靠性指标。
With independent and autonomous operation characteristics of islanded microgrid, the internal load is power supplied normally and effectively. Firstly, sequential output model of wind turbine is built. According to different operating strategies and characteristics of energy storage system （ESS）, a charge-discharge model of ESS is established. Secondly, based on sequential Monte Carlo simulation, a reliability evaluation algorithm is proposed considering the characteristics of randomness and time sequence. Finally, the reliability of improved RBTS Bus 6 islanded system is evaluated. Evaluation results show that the algorithm can analyze the reliability of islanded microgrid system accurately.
