摘要:

针对氢-电混合储能系统的运行模型和多端柔性直流配电网的电压-功率下垂特性二次调节过程,提出了一种源-储-网联合多时间尺度优化调度策略。日前调度阶段以运行成本和电压偏差率最小为目标,优化混合储能运行模式、微型燃气轮机的启停与下垂特性二次调节参数,为日内优化调度提供参考;日内滚动优化调度阶段以经济性为目标,微调设备出力并修正预测误差带来的功率波动。以某环形多端直流配电网为例,验证了所提调度策略的可行性、混合储能的优势和下垂特性二次调节对运行的改善。

Abstract:

According to the proposed operation model of hydrogen-power hybrid energy storage systems and secondary adjustment process of voltage-power droop characteristics in multi-terminal flexible DC distribution networks, a multi-time-scale optimal scheduling strategy for source-storage-network coordination is proposed. The objective of day-ahead scheduling is to minimize the operation cost and voltage deviation. It also optimizes the operation mode of hybrid energy storage, the on-off of micro-turbines and the secondary adjustment parameters of droop characteristics to provide the reference for intra-day optimal scheduling. Intra-day rolling optimal scheduling takes the economy as its objective to fine-tune the output power of equipment and compensate the power fluctuation caused by forecast errors. A case study is undertaken in an annular multi-terminal DC distribution network to verify the feasibility of the proposed scheduling strategy, the advantages of hybrid energy storage, and the improvement of operation by the secondary adjustment of droop characteristics.
