从电力市场角度出发,根据双馈风电机组(DFIG)的输出功率运行分区进行无功定价。建立以系统经济指标、电压偏移和电压稳定L指标为目标函数的多目标无功优化模型。提出了一种交互式蜜蜂交配优化算法对其进行求解。在算法的寻优机制中嵌入非劣排序和拥挤距离排序进行选择操作,使其收敛到Pareto前沿,并保证了非劣解的均匀分布。利用IEEE 30节点系统进行算例分析,并与其他算法进行对比,结果验证了所提算法的可行性、有效性及优越性。

目的构建负载淫羊藿苷(ICA)和盐酸米诺环素(MH)的明胶微球/骨水泥(GMs/CPC)材料并对其性能进行研究,为种植体周围炎的治疗提供一种骨替代材料。方法制备GMs及负载ICA的GMs(ICA)、负载MH的GMs(MH)和同时负载两种药物的GMs(ICA+MH),将GMs(ICA+MH)与CPC复合构建CPC/GMs(ICA+MH)材料,将GMs(ICA)和GMs(MH)按照质量比1∶1的比例混合后与CPC复合构建CPC/GMs(ICA)+GMs(MH)材料。通过扫描电镜实验观察材料表面形态,X射线衍射实验分析材料物相。将各组材料浸提液作用于骨髓间充质干细胞(BMSCs),通过CCK-8实验检测材料浸提液对BMSCs增殖作用的影响,通过茜素红染色及钙含量定量分析实验检测材料浸提液及含浸提液的矿化液对BMSCs矿化作用的影响。结果扫描电镜观察显示,CPC/GMs、CPC/GMs(ICA+MH)和CPC/GMs(ICA)+GMs(MH)中的明胶微球被CPC基质包裹并随机散在分布于骨水泥中;X射线衍射分析结果显示以上3种材料中明胶微球与CPC结合后并未发生化学反应产生新的物质。CCK-8实验结果显示,BMSCs在材料浸提液中培养7 d后,CPC/GMs(ICA)+GMs(MH)组BMSCs的增殖率显著升高,与CPC/GMs组和CPC/GMs(ICA+MH)组比较差异具有统计学意义(P<0.05)。BMSCs在材料浸提液及含浸提液的矿化液中培养21 d后,CPC/GMs(ICA)+GMs(MH)组矿化能力显著高于CPC/GMs组和CPC/GMs(ICA+MH)组(P<0.05)。结论CPC/GMs(ICA+MH)和CPC/GMs(ICA)+GMs(MH)材料对BMSCs的成骨分化均具有促进作用,其中CPC/GMs(ICA)+GMs(MH)的作用较强是一种优选的骨替代材料。
