摘要
为解决远洋海岛微电网群规划无法灵活应对台风天气的问题,基于常规场景、台风场景和台风预警场景构建了电-氢-淡水能源物资包最优配比模型并通过储能船舶进行运输。根据实际工况将长期规划决策与短期运行调度相结合,建立海岛微电网群双层规划模型。上层以最小化投资成本和运行成本为目标建立规划模型,下层建立运行模型,旨在最小化运行成本、燃气轮机弥补出力成本以及在台风预警场景下实现储能最大化。最后,采用C&CG算法不断迭代求解运行层以及重构后的规划层,实现对双层规划模型的快速求解。仿真结果表明,考虑能源物资包最优配比后,系统综合成本有所降低,且减少了弃风弃光现象的发生。
To address the issue of inflexibility in responding to typhoon weather conditions in the pelagic island microgrid group,an optimal configuration model of energy,hydrogen,and freshwater energy resource packages was constructed based on regular scenarios,typhoon scenarios,and typhoon early warning scenarios,and transported via energy storage ships.By integrating long-term planning decisions with short-term operational scheduling based on actual operational conditions,a double-layer planning model for microgrid clusters on islands is established.A double-layer planning model for the island microgrid group was established.The upper layer aimed to minimize investment and operating costs,while the lower layer focused on operational modeling to minimize operating costs,gas turbine output compensation costs,and maximize energy storage under typhoon warning scenarios.The C&CG algorithm is finally used to solve the operation layer and the reconfigured planning layer iteratively to realize the fast solution of the double-layer planning model.The simulation results indicate that considering the optimal configuration of energy resource packages leads to a decrease in the overall system cost and a reduction in wind and solar power curtailment.
