Large Scale Grid Integration of Renewable Energy Sources — Recommend this title to your library

Thank you

Your recommendation has been sent to your librarian.

The large-scale integration of VRE into power grids requires substantial transformations to increase the power system flexibility: (1) to allow bidirectional electricity flow, which is aimed to ensure grid PQR when including DER; (2) to establish DR mechanisms aimed at reducing peak-loads in order to deal with increased variability; (3) to expand grid interconnection at the regional and international level aimed at increasing balancing capabilities and stability; (4) include technologies and procedures to ensure adequate stability and control (e.g., frequency, voltage, power balance) in the presence of VRE and (5) to exploit the ESS potential to store electricity surplus from VRE. Smart grids have the potential to benefit the whole value chain so that system operators can get the required power security and quality of supply.
