【摘要】：储能装置可有效平抑间歇性分布式电源的出力波动,有助于提高系统运行的可靠性。然而,储能装置运行策略和运行特性的选取对系统可靠性水平有着重要影响。搭建了计及储能运行策略和运行特性的、更为精准的储能充放电模型,提出了基于序贯蒙特卡洛模拟法的风/光/柴/储微电网可靠性评估模型,并分别针对负荷点、系统和储能提出了一系列评估指标。通过对IEEE-RBTS标准算例系统进行仿真,分析了储能装置的运行策略、容量、最大充放电功率对微电网可靠性水平的影响,并评估了切负荷策略中位置权重系数对负荷点及系统可靠性水平的影响,评估结果可为微电网的优化规划提供有益参考。
[Abstract]:The energy storage device can effectively suppress the force fluctuation of intermittent distributed power supply and help to improve the reliability of the system. The selection of operation strategy and operating characteristics of energy storage device has an important impact on the reliability level of the system. A more accurate energy storage charging and discharging model considering the operation strategy and characteristics of energy storage is built. The reliability evaluation model of wind / light / firewood / microgrid based on sequential Monte Carlo simulation method is proposed, and the load points are respectively targeted. System and energy storage proposed a series of evaluation indicators. Through the simulation of IEEE-RBTS standard example system, the operation strategy and capacity of energy storage device are analyzed. The influence of maximum charge and discharge power on the reliability level of microgrid is evaluated. The influence of position weight coefficient on load point and system reliability level in load shedding strategy is evaluated. The evaluation results can provide a useful reference for the optimization planning of microgrid.
