In this paper. a novel fast short circuit current detection technique is proposed for PV inverter based DGs. The proposed short circuit current detector is based on the evaluation of the slope (d dt) and magnitude of the PV inverter current. As soon as it detects a fault that is …

A comprehensive system leveraging mobile and RFID technologies. aggregation middleware and an aggregated charge-scheduling algorithm that effectively schedules charging and V2G operations for cost savings and peak load reduction has been presented. Intelligently scheduled charging yields a cost savings of 7% for enterprise commuters and 10% for drivers with variable …

As the demand for “green“ energy increases the offshore wind power industry is expanding at a rapid pace around the world. Design of Foundations for Offshore Wind Turbines is a comprehensive reference which covers the design of foundations for offshore wind turbines. and includes examples and case studies. It provides …

This book presents currently available renewable energy technologies (RETs) and explores their possible integration into the economically viable and green residential microgrids of tomorrow. The emphasis is on the importance of RETs in today’s energy-efficient building designs. and on those RET mathematical models suitable for both performance simulation and economic …

Based on comparative study on different pole-slot number combinations and pole-arc coefficients for the 1.5MW directdriven PM wind generator. the following conclusions can be deduced: 1) The pole-slot number combination has significant effect on the positioning torque at no load. Choosing the fractional slot number per pole and per phase …

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 …
