The steady state behaviour of an interconnected DFIG based wind farm with STATCOM and SVC is studied and compared for performance evaluation of the two FACTs devices. . A case was developed in which when the load is connected at the point of common coupling there is a voltage dip …

With an increase of global energy demand arising in urban settlements. the key challenges for the urban energy transition include analysis of energy efficiency options and the potential of renewable energy systems within the existing building stock. making cities a key actor in the transition success. In Urban Energy Systems …

Dynamics and Control of Electric Transmission and Microgrids offers a concise and comprehensive review of the most recent developments and research in grid dynamics and control. In addition. the authors present a new style of presentation that highlights the role of transmission and distribution grids that ensure the reliability and …

The GSC control algorithm of the proposed DFIG has been modified for supplying the harmonics and reactive power of the local loads. In this proposed DFIG. the reactive power for the induction machine has been supplied from the RSC and the load reactive power has been supplied from the GSC. …

In this paper a new topology for wind turbines based on doubly-fed induction generator was proposed. The idea behind that work is use the FACTS features of the WT-DFIG to improve the power quality into the point of common coupling (PCC). Besides the inherent advantages to the active filters. through …

The present study provides a systematic approach to derive a large collection of methods to determine the series resistance of a solar cell. Representation of the methods in the two-dimensional array presented in Table 1 allows for easy comparison and reveals that many previously published methods are more alike than …

The new formulation for the electrical modeling of the three-level converter combined with the new control strategy reveals the capability in mitigating the unbalancing between the capacitors bank voltages. The THD of the output current with the two-level converter and with the three-level converter have propensity to be decremented with …

Application of Smart Grid Technologies: Case Studies in Saving Electricity in Different Parts of the World provides a wide international view of smart grid technologies and their implementation in all regions of the globe. A brief overview of smart grid concepts and state-of-the art technologies is followed by sections that …

The creation of a flexible. efficient. digitized. dependable and resilient power grid may well be the best route to increasing energy efficiency &amp. security. as well as boosting the potential of renewable &amp. distributed power sources. This book covers smart grids from A-Z. providing a complete treatment of the topic. …

This paper investigates the role of reactive power compensator STATCOM and presents a control system based on simultaneous control of STATCOM reactive power and pitch angle of rotor blades for improving stability margin of speed of induction generator. As it can be seen in Fig. 12. critical clearing time i.e. …
