In this paper, a stand-alone hybrid renewable energy system is proposed, which consists of solar PV, wind turbine, and energy storage with the combination of battery and hydrogen. This energy storage system partly relies on energy conversion through two components, electrolysis and fuel cell. When the hybrid system generates more electricity than load demand, hydrogen is produced via electrolysis...
Now a days, Superconducting fault current limiter (SFCL) is emerged as one of the most accomplished fault current limiter (FCL) In this Paper, a flux coupling type SFCL is designed for limiting the fault current in isolated wind turbine generation system. The proposed Resistive and flux Coupling based super conducting fault current limiters have improved performance in terms of current limitation,...
Several factors affect the power generation efficiency of wind energy extracted from wind turbines. One of them is dust accumulation resulting in roughness of the blade surface and resulting in power loss. To overcome this problem, wind turbine blades need to be cleaned frequently. There are some existing techniques of cleaning but not very efficient and economically viable. In this paper, we have...
For a safe and efficient operation of large variable-pitch wind turbines, the controller plays a vital role. Below the rated wind speed, there is a power-optimal rotor speed for a given wind speed, achieved by designing a generator torque control. Pitch control is appropriate above the rated wind speed, to keep the rotor speed constant. In order to deal with nonlinearities and uncertainties, in this...
Currently, the contribution of renewable energy in isolated power systems are not fully exploited. The intermittent nature of renewable energy resources limits renewable energy contribution in electricity supply mix. This paper presents an overview of wind power intermittency and potential solutions. A case study about a combined wind Pumped Hydro Energy Storage (PHES) power plant in an isolated power...
An 8×8 (64) Internet of Things (IoT) wind farm platform is built using miniaturized wind turbines with wireless connectivity. The farm is being deployed on the south east coast of Ireland to remotely collect data for offline evaluation of a data driven wind turbine power output model and study aerodynamic interactions between turbines within the farm. The cluster is build such that a range of different...
This paper proposes a modeling and control to enhance a grid on/ofï operation of a single-phase system consisting of a Single-Phase Five-Level Inverter (SPFLI). The Sliding mode control is adopted to compensate the current harmonics, the reactive power and the regulation of the DC bus voltage at the PCC during grid operation. The renewable energy based PMSG wind turbine is used to reduce the energy...
