考虑动态频率响应的孤岛微电网日前—日内两阶段高分辨率优化调度
Gaoya dianqi高比例新能源渗透的微电网具有惯量低、系统动态频率响应能力弱等特征，处在孤岛运行模式的微电网频率更易受波动。针对微电网频率稳定性问题，将动态频率响应模型加入到优化调度中，推导系统频率安全约束以提高系统调频能力。含动态频率响应约束的调度模型具有多约束、非线性、高维等特征，现有研究中忽略了调度模型线性化的影响。基于此，在考虑动态频率响应的孤岛微电网日前—日内两阶段优化调度模型中引入日内高分辨率离散策略，在日前优化调度的基础上选取能更好的拟合系统净负荷出力曲线的高分辨率进行日内优化调度，修正日前调度计划。最后 ...

Rare Metals, EarlyView.ABSTRACT MCrAlX coatings are widely used as bond coats in thermal barrier coating systems to protect turbine blades from high‐temperature oxidation. However, their oxidation resistance is often restricted by uncontrolled microstructures, surface roughness, and aggregation of reactive elements (REs). In this study, high‐repetition‐rate femtosecond laser

Gaoya dianqi针对风电制—储氢系统的优化调度问题，提出了一种考虑碱性电解槽状态转换的日前出力优化调度模型。该模型以系统日收益最高为目标，结合分时电价，引入电解槽状态转换过程中的冷热启动成本和功率波动成本，满足各个设备动态运行约束及系统功率平衡约束条件，调用Gurobi求解器进行优化求解。采用实际的风电出力数据和电氢负荷数据，对3种典型日场景下的优化结果进行分析。算例表明：所建立的优化调度模型能够满足电氢负荷需求，合理调节电解槽的3种状态，显著降低电解槽功率波动幅度和系统总成本，验证了所提模型的有效性。
