摘　　要：近几十年来,考虑到环境问题和化石燃料的缺乏,可再生能源的整合程度大大提高。由于其不确定性,这种整合在电力系统中出现了新的挑战。氢能储存系统(HES)在电力系统中扮演着重要的角色,它通过使用电力制氢(P2H)技术将额外的风力转化为氢气。此外,热电联供(CHP)机组等新兴技术也能有效提高电力系统的效率。提出了一种基于CHP-HES的电能网络的日前调度方案,并对风电资源进行了高度整合。通过在IEEE 6-总线系统上的实施,研究了所提出的模型的有效性。研究了热负荷增量对发电设备调度、风电调度和系统运行成本的影响。仿真结果证明,采用HES技术后系统的运行成本和风力发电量的缩减都有所降低。In recent decades,the integration of renewable energy sources had greatly increased,taking into account environmental concerns and the lack of fossil fuels.Due to their uncertainty,this integration has presented new challenges in the power system.Hydrogen energy storage systems(HES)play an important role in the power system by converting additional wind power into hydrogen using power to hydrogen(P2H)technology.In addition,emerging technologies such as combined heat and power(CHP)units can effectively improve the efficiency of power systems.A day-ahead scheduling scheme for CHP-HES-based power networks was proposed with a high degree of integration of wind power resources.The effectiveness of the proposed model was investigated through its implementation on IEEE 6-bus system.The effect of heat load increment on generation equipment scheduling,wind power scheduling and system operating costs were investigated.The simulation results demonstrate that the operating cost of the system and the curtailment of wind power generation are reduced by using HES technology.
