In this standard, the maximum modulation frequency for the phasor domain oscillations is 5 Hz. The synchrophasor reporting rates below 10 frames/s are exempted from the dynamic requirements of the standard. Synchrophasors reported below 10 frames/s cannot be used in the dynamics monitoring applications due to violation of the Nyquist theory (considering maximum 5 Hz oscillation frequency). Recently, compressive sampling (CS) theory has generated significant interest in the signal processing community because of its potential to enable signal reconstruction from fewer samples than suggested by the Nyquist rate. In this paper, the CS theory has been used to reconstruct the signal dynamics at higher rates using synchrophasors reported at the sub-Nyquist rate. This cannot be achieved in the conventional interpolation theory due to aliasing. As an example, in this paper, synchrophasors of an amplitude and frequency modulated (5 Hz) waveform are reported at 8 frames/s; thus causing aliasing. This aliased data is used in the phasor data concentrators (PDCs) to accurately (low TVE) reconstruct the synchrophasors at 24 frames/s rate using CS theory. The results indicate that the CS theory may also be useful in reducing the communication bandwidth requirements.","PeriodicalId":268687,"journal":{"name":"2013 IEEE PES Innovative Smart Grid Technologies Conference (ISGT)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124611715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are too many nodes with different data packets which need to be delivered to BS. But BS can't satisfy the delay requirements of different data because of limited resources through SCM. In order to meet the QoS requirements of different priority data, we introduce Multi-hop Communication Mode (MCM) into this scenario to improve the network's performance by adding another wireless interface on each node (DA or DB), such as wifi or zigbee. We present a framework in which a relay node is chosen according to the node's energy consumption and its residual energy, and DB equipped with large capacity battery is chosen as the cluster header, which helps to forward DAs' data to BS. Our main idea is that each node decides which communication mode the packet should use based on its priority and Residual Life Time (RLT). According to packet's RLT, one node can decide whether it should send it right now through single-hop, or put it into the corresponding queue and then send it to the next hop (multi-hop), or drop the packet. In a node, different priority data packets are put into different priority queues. In each queue, packet is sorted according to its RLT. When the first packet needs to be sent out, the node combines the first few packets in the same queue into a large packet, and then sends it out. The simulation shows our scheme can satisfy the performance requirement of smart grid.","PeriodicalId":268687,"journal":{"name":"2013 IEEE PES Innovative Smart Grid Technologies Conference (ISGT)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128413834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we investigate the application of a novel approximate dynamic programming (ADP) architecture, goal representation heuristic dynamic programming (GrHDP), to a large benchmark power system. Unlike traditional ADP design with an action network and a critic network, GrHDP integrates the third network, a goal network, into the actorcritic design (ACD) to automatically and adaptively build an internal reinforcement signal representation to facilitate learning and optimization. Then the GrHDP is employed to control the benchmark power system including a DFIG based wind farm and a STATCOM with HVDC transmission. Various power system states, including the voltage of STATCOM, current of DFIG and DC current of HVDC inverter, are provided to the GrHDP controller to generate three adaptive supplementary control signals. These adaptive supplementary control signals are then provided to the STATCOM controller, DFIG rotor side controller and HVDC master control, respectively. This control structure is validated in Matlab/Simulink to demonstrate its effectiveness in power system control.","PeriodicalId":268687,"journal":{"name":"2013 IEEE PES Innovative Smart Grid Technologies Conference (ISGT)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128249969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
