Research on Large‑scale Photovoltaic Planning Based on Risk Assessment in Distribution Network
Lei Wang,Minyu Yuan,Fan Zhang,Xuli Wang,Jing Ma,Lei Dai,Xianjun Qi,Rui Bi 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.3
Risks caused by large amounts of distributed photovoltaic (PV) feeding into distribution networks, have an impact on PV planning, which has become a critical consideration for distribution networks’ operation. In this paper, a large-scale PV planning method is proposed which based on risk assessment in distribution networks. Cluster division is used to group large-scale distributed PVs. A risk assessment is performed on the distribution network, considering the correlation between PVs and loads. The efects of load fuctuations, PV quantity, capacity and location on the operational risk of the distribution network are analyzed and discussed. A large-scale PV planning model is established with the goal of maximizing the comprehensive benefts, considering the penalty cost of node voltage over-limit and branch power fow over-limit risk. Finally, the genetic algorithm is used to solve the planning model. The simulation results demonstrate the efectiveness of the proposed method.

Rice sheath blight (SB), caused by Rhizoctoniasolani (R. solani), is a major threat to rice productionworldwide. The molecular mechanisms of the SB resistancein rice are poorly understood. The transcriptomes of the SBresistantrice cultivar YSBR1 and the susceptible cultivarLemont were analyzed after R. solani infection. A total of7624 differentially expressed genes (DEGs) were identifiedat one or more timepoints in a cultivar. 5526 and 5618 DEGswere differentially expressed in Lemont and YSBR1,respectively. YSBR1 exhibited stronger and earlier transcriptionalresponse to R. solani than Lemont. Gene ontology enrichmentanalysis revealed that genes that encode cell wall-modifyingand glycosyl-degrading enzymes or anti-microbial proteinswere specifically induced in YSBR1 at 6 hpi. MapMananalysis revealed that more DEGs related with cell wall, β-glucanses, respiratory burst, phenylpropanoids and ligninwere highly induced by R. solani in YSBR1 than in Lemont. The results also showed that receptor-like kinases and jasmonicacid signaling may play important roles in host resistance toR. solani. This study highlights potential candidate genes andsignaling pathways involved in rice sheath resistance and canhelp to further clarify the mechanistic events underlyingresistance and susceptibility to R. solani.

A Heterogeneous Multi-core DSP Architecture for OFDM-Based Communication Systems
Xu Li,An Peng,Wang Yu,Li Jun 보안공학연구지원센터 2016 International Journal of Future Generation Communi Vol.9 No.10
As a kind of wireless communication system, OFDM systems are widely used in the current and next generation wireless communications. According to the characteristics of OFDM systems, this paper proposed a new heterogeneous multi-core DSP architecture for OFDM system - HeteroM-DSP. Hetero M-DSP based on VLIW DSP core, which has good Data-Level Parallelism and Instruction-Level Parallelism. Each independent DSP core through sharing memory, task scheduling bus and bus controller based open-ring interconnection, improve the communications parallelism between DSP cores. Meanwhile, in order to implement different OFDM systems flexibly, each DSP core has different computational capabilities. It is also improved processor performance/ power rate. Experimental results for the IEEE 802.11a receiver show that Hetero M-DSP can efficiently use for OFDM systems.

Low Power Gated-Clock Design for Multi-core DSP Based SDR Platform
Xu Li,An Peng,Wang Yu,Li Jun 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.6
With the rapid development of wireless communication systems, multi-core DSP with high computing performance is an important part of SDR (Software-Defined Radio) platform. Research has focused on low-power design in SDR platform since the SDR platform is sensitive to power consumption. Following the baseband digital signal processing features of SDR application, this paper proposes a data-driven and task-driven gated-clock architecture. The DSP cores in the multi-core DSP can be turned on and turned off with this architecture at the appropriate time. Experiments show that the proposed low power gated-clock architecture can provide effective low-power performance for multi-core DSP in SDR platforms.

Little is known about the distribution of fungal communities with soil depth on relatively large scales. In this study, typical paddy soils in three regions (Hailun, Changshu, and Yingtan) from north to south China were selected to investigate the vertical distribution (0-100 cm) of the fungal community by Illumina MiSeq sequencing, and to identify the main factors influencing the fungal community distribution. The results indicated that the structure of the soil fungal community changed significantly with region and soil depth. Soil fungal taxa such as Zygomycota, Glomeromycota, Saccharomycete, Kazachstania, Mortierella, Massariosphaeria, Hypholoma, and Zopfiella were enriched at depths of 0–20 cm, whereas Dothideomycetes, Microbotryomycetes, Tremellomycetes, Sporobolomyces, Cryptococcus, Rhodotorula, Fusarium, and Pyrenochaetopsis had high relative abundances at 80–100 cm. Variance partitioning analysis indicated that the geographic distance contributed more to the fungal community variation than environmental variables on a large scale. In addition, soil total carbon and nitrogen contents were the main environmental factors driving the vertical distribution of the fungal community in paddy soils.
