In this paper. we proposed a multilevel approach for optimal participation in reactive power balancing of wind farms connected to the transmission grid. For this purpose. we defined reactive power capability of a DFIG wind turbine. Afterwards. we proposed a method to find the reactive power capability of a wind …

In this paper. the harmonic emissions of a 30 × ۶۰۰ kW WT SCIG wind farm are analyzed using field measurements to contribute to the understanding of wind farm harmonic behavior. The following conclusions can be drawn from the investigation. 1) Low-order characteristic harmonics are the dominant ones in the …

The model of a small stand-alone AC system with fuel cell and solar panel was implemented and simulated with Simulink. The preliminary result shows the feasibility of including dynamic models of the renewable energy resources in the analysis of the system performance. The research of the power management strategy and …

In this work. the most widely used MPPT algorithms have been modeled and evaluated according to simulations in Matlab Simulink environment based on the dynamic response of the PV system. the tracking speed of convergence. the efficiency and the ease of implementation. The results indicate that the modified fractional OC …

This paper presented the frequency regulation of hybrid renewable power generation system by coordination control of WTG and the DLC system. In the proposed method. the load variation is reduced by FC in low frequency domain and the DLC bank in high frequency domain. By using the proposed method. the …
