研究光伏场景聚合是实现区域电网分布式光伏与储能联合规划的前提和基础,对促进配电网分布式光伏的充分消纳具有重要作用.通过基于改进的K-means++算法对历史光伏数据进行聚合分析,得到光伏出力的典型场景聚合,从配电网的经济性出发,兼顾系统运行的可靠性、环保性,建立考虑光伏场景聚合的光储选址定容规划模型,引入层次分析法(analytic hierarchy process,AHP)将多目标优化问题转化为单目标问题,并利用粒子群算法(particle swarm optimization,PSO)进行求解.算例结果表明,提出的光伏场景聚合模型更准确刻画光伏出力的不确定性,验证了该模型的有效性和可行性.

The progress on Chinese Space Solar Telescope (SST) in 2002-2004 is introduced. The documentations on plans and outlines based on the standards of Chinese aerospace industry for SST mission has been fulfilled. The key technical problems of SST satellite platform and payloads are tackled during pre-study stage of the mission. The laboratory assembly and calibration of the main optical telescope of 1.2 m spherical mirror and 1 m plain mirror have been carried out with the accuracy of λ/40 and λ/30, respectively. The prototype at 17.1 nm for extreme ultraviolet telescope is under development and manufacture with a diameter of 13 cm. Its primary and secondary mirrors have a manufacturing error of 5nm with a roughness degree of less than 0.5 nm and a multiplayer reflection factor of better than 20%. The on-board scientific data processing unit has been developed. Prototypes for other payloads such as H and white light telescope, wide band spectroscopy in high energy and solar and interplanetary radio spectrometer have been developed accordingly.

We study adaptive control for a family of nonlinear systems, involving unknown and uncertain parameters. The proposed control law estimates the system parameters adaptively and stabilizes the closedloop system asymptotically for the initial state over any given bounded set of the state-space. Moreover,reconstruction filters are designed to obtain error residue signals and to enable the use of the least-squares algorithm for estimating the parameters, in order to achieve the convergence based on the persistent excitation condition and asymptotic linearization. The proposed methods are applicable to full actuation and under actuation control systems. Simulation studies are carried out for a pendulum system and for a third-order vehicle model, as well as control of vehicle platoons, validating the theoretical results presented in this paper.

随着蜂窝网络数据流量需求的高速增长,对于未来时刻蜂窝流量情况的精准预测,可以帮助改善网络资源分配、实现流量负载均衡,并部署基站节能与休眠策略。基于轻量化线性瓶颈结构,提出了一个具有多个并列分支结构的空时预测模型,分别提取近期历史数据和周期性历史数据中的空时特征。对于网格化空时数据中的空间依赖性,额外通过K-Means算法对网格高维特征进行聚类,并提取网格基站密度信息作为跨域特征输入到模型中,实现了使用低复杂度、低算力需求模型对研究范围全域流量的精准预测。
