This paper describes an introduction into ocean wave energy converter and it's impacts on power system. There are a lot of methods and systems for converting wave power into electrical power, The most common structure of wave power plant is Oscillating Water Column (OWC) plant. The turbine employed in OWC plant is normally Wells turbine. The Wells turbine has inherent disadvantages such as low efficiency, and poor starting characteristics. The objective of this paper is introduction of Wells turbine with fixed guide vanes in order to improve turbine performance. Modeling and computer simulation of OWC power plant components are presented and effect of out power fluctuation on power system is investigated. [ABSTRACT FROM AUTHOR]

This paper presents power flow models of a self-excited induction generator. These models are used for steady-state power flow calculation in electric power systems in which a generating plant driven by renewable energy sources, such as wind energy, is connected to partially serve loads.?? This research demonstrates the induction generator by two forms: i) power (PQ) model and ii) admittance (Y) model. Solution convergence and model accuracy are observed in order to predict power flow distribution through feeder lines resulting from the grid connection of a renewable power plant. From the proposed models, voltage profiles of the system can be calculated. To verify the effectiveness of the proposed models, standard IEEE 37-node, 118-node test feeders and a 22-kV power distribution systems in Nakhon Ratchasima, Thailand, were examined. In addition, satisfactory results can be employed to develop system stability analysis and operation planning in order to prevent supply service interruption and conserve the overall electrical energy.
