Wireless Coding Deadbeat Power Control For Doubly-fed Induction Aerogenerators In Smart Grid Applications [controle Deadbeat Codificado Sem Fio De Potencias Para Aerogeradores De Inducao Duplamente Alimentados Visando Aplicacoes Em Redes Inteligentes]

Smart grids comprise advanced communication infrastructure to provide balance supply, demand, and storage of energy over a region in a much more efficient manner than it is done today. However, in a smart grid, the utilization of wireless technologies for transmitting control information requires a powerful error protection to avoid any serious problems to the energetic plant. With this focus, the work is concerned with a wireless coding deadbeat power control system for a variable speed wind doubly-fed induction generator for smart grid applications.235541552Adamowicz, M., Strzelecki, R., Krzeminski, Z., Szewczyk, J., Lademan, L., Application of wireless communication to small WECS with induction generator (2010) IEEE Mediterranean Electrotechnical Conference, pp. 944-948Adamowicz, M., Strzelecki, R., Krzeminski, Z., Szewczyk, J., Lademan, L., Wireless short-range device for wind generators (2010) 12th Biennial Baltic Electronics Conference, pp. 1736-3705Anaya-Lara, O., Jenkins, N., McDonald, J.R., Communications requirements and technology for wind farm operation and maintenance (2006) IEEE International Conference on Industrial and Information Systems, pp. 173-178Barbieri, A., Piemontese, A., Colavolpe, G., On the ARMA approximation for frequency-flat rayleigh fading channels (2007) IEEE International Symposium on Information Theory, pp. 1211-1215Blau, J., Europe plans a north sea grid (2010) IEEE Spectrum, pp. 08-09Brink, S.T., Kramer, G., Design of repeataccumulate codes for iterative detection and decoding (2003) IEEE Trans.

A Wind Energy Generator For Smart Grid Applications Using Wireless-coded Neuro-fuzzy Power Control

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Wind energy is the major driver to obtain an optimized and efficient use of renewable energy in smart grids. To provide balanced supply, demand, and storage of energy in a much more efficient manner than is done today, smart grids require the employment of an advanced communication infrastructure associated to a robust power control and real-time monitoring systems. Towards this objective, we present a wireless-coded power control scheme for doubly fed induction generators operating at variable speed. The proposed system employs adaptive neuro-fuzzy control, quaternary phase shift-keying modulation, and low-density parity check coding techniques to improve the system robustness and reliability in different propagation conditions for remotely transmitting the power control references from the control center to a given aerogenerator.681221122123CAPES; Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Ilic, M.D., From hierarchical to open access electric power systems (2007) Proceedings of the IEEE, 95 (5), pp. 1060-1084Li, F., Qiao, W., Sun, H., Wan, H., Wang, J., Xia, Y., Xu, Z., Zhang, P., Smart transmission grid: Vision and frameworks (2010) IEEE Transactions on Smart Grid, 1 (2), pp. 186-192Manwell, J.F., McGowan, J.G., Rogers, A.L., (2010) Wind Energy Explained: Theory, Design and Application, , second ed.

An Anfis Power Control For Wind Energy Generation In Smart Grid Scenario Using Wireless Coded Ofdm-16-qam

The wind energy generation is the huge driver behind the push for supergrids and cross-border infrastructure for renewable energy systems into smart grids. To provide balance supply, demand, and storage of energy over a region in a much more efficient manner than it is done today, smart grids will need to use an advanced communication infrastructure into a robust control system. Towards this objective, this work proposes a wireless coded orthogonal frequency division multiplexing neuro-fuzzy power control employing low density parity-check coding for a doubly fed induction aerogenerator to improve system robustness and reliability. The performance improvements of the proposed system are investigated in a more realistic frequency selective fading propagation condition. © Brazilian Society for Automatics-SBA 2013.2512231Adamowicz, M., Strzelecki, R., Krzeminski, Z., Szewczyk, J., Lademan, L., Application of wireless communication to small wecs with induction generator (2010) 15th IEEE Mediterranean Electrotechnical Conference, pp. 944-948Adamowicz, M., Strzelecki, R., Szewczyk, J., Lademan, L., Wireless short-range device for wind generators (2010) 12th Biennial Baltic Electronics Conference, pp. 1736-3705Almeida, R.G., Lopes, J.A.P., Participation of doubly fed induction wind generators in system frequency regulation (2007) IEEE Transactions on Power Systems, 22 (3), pp. 944-950Azcue, J.L., Sguarezi Filho, A.J., Capovilla, C.E., Casella, I.R.S., Ruppert, E., A wind energy generator for smart grid applications using wireless coding neuro-fuzzy power control (2012) International Conference on Fuzzy Systems and Knowledge Discovery, pp. 525-530Belmokhtar, K., Doumbia, M.L., Agbossou, K., Modelling and fuzzy logic control of dfig based wind energy conversion systems (2012) IEEE International Symposium on Industrial Electronics, 2 (4), pp. 1888-1893Berrou, C., Glavieux, A., Thitimajshima, P., Near shannon limit error-correcting coding and decoding: Turbo-codes (1993) IEEE International Communications Conference, pp. 1064-1070Casella, I.R.S., Analysis of turbo coded ofdm systems employing space-frequency block code in double selective fading channels (2007) IEEE International Microwave and Optoelectronics Conference, pp. 516-520Casella, I.R.S., Sguarezi Filho, A.J., Capovilla, C.E., Ruppert, E., A wireless deadbeat power control for wind power generation systems in smart grid applications (2011) Brazilian Power Electronics Conference (COBEP), pp. 520-523Datta, R., Rangathan, V.T., Variable-speed wind power generation using doubly fed wound rotor induction machine: A comparison with alternative schemes (2002) IEEE Transactions on Energy Conversion, 17 (3), pp. 414-421Dinoi, L., Sottile, F., Benedetto, S., Design of versatile eira codes for parallel decoders (2008) IEEE Transactions on Communications, 56 (12), pp. 2060-2070(2005) Dvb-s.2.
