摘　　要：针对海上油气田电网对具有不确定性的海上风电的消纳难题,提出了基于燃气/燃油透平发电机与储能协同的海上油气田电网分层调控策略。首先,分析了海上油气田多能耦合特征以及含海上风电的海上油气田能源系统典型结构。在此基础上,提出了基于日前与日内优化调度的海上油气田综合能源系统分层调度策略,以平抑海上风电小时级不确定性。进一步,提出基于饱和滤波器的快速功率分配策略,通过储能与燃气/燃油透平发电机协同平抑海上风电的分钟级和秒级不确定性。最后,通过算例分析说明,所提分层调控策略能有效降低运行成本,提升海上风电的消纳能力。To support the integration of intermittent offshore wind power,a hierarchical control method based on the coordination of turbine generators and energy storage was developed for power grids of offshore oil and gas platforms.First,the multi-energy coupling characteristics and structures of offshore oil and gas platform energy systems were analyzed.Subsequently,a hierarchical control strategy was devised based on day-ahead scheduling and intraday horizon dispatch to smooth uncertainties at hourly level.Furthermore,a saturated filter-based power dispatch strategy was developed to coordinate turbine generators and energy storage to smooth the uncertainties at minute and second levels.Finally,the proposed strategy was tested using data from a real offshore oil and gas platform energy system.The results show that the proposed strategy can reduce the operating cost while supporting the integration of wind power.
