摘要:
      风储一体化运行是未来风电站的一种发展趋势,与储能和风电分别受系统调度相比较,更有利于提高风电接入电网的利用率。基于一体化电站中电池储能系统的运行特性及风机故障机理,提出考虑含风储一体化电站的电力系统失负荷和弃风风险指标,建立以系统运行风险最小、火电机组煤耗量最少,以及弃风量最少的多目标优化调度模型,以解决系统运行过程中风险、发电成本与风电消纳之间的矛盾。算例验证表明,与传统风储联合运行模式下的调度结果相比,一体化后虽然风险略有增加,但显著提高了系统运行的经济性和风电消纳能力。
Abstract:
      The integrated operation of wind power and energy storages is the development trend of wind power station. Compared with the energy storage and wind power separately dispatched by the system, the utilization ratio of wind power is improved through the integration of wind farms and energy storages. Based on the operation characteristics of battery energy storage system and the failure mechanism of wind power generators of the integrated station, the loss of load and wind abandoning risk indicators of the integrated operation of wind power and energy storage are built up. A multi-objective optimization dispatch model with the minimum coal consumption of thermal power unit, minimum risk and minimum wind curtailment capacity is proposed. The contradiction in the operation of power system is solved among the risk and coal consumption and wind consumption capacity. The computation example verifies that the model improves the economic efficiency and wind power utilization clearly in the operation of the power system after integration, even though the risk increases a little compared with the traditional unified operation of wind power and energy storage.
