“…In [119], an adaptive overcurrent protection strategy consisting of a realtime conventional block was introduced. An adaptive protection system that monitors and updates the setting of relays online according to the operating modes of the DPGS was proposed in [120]. It employs communication links to collect data from intelligent electronic devices, and then the data are sent to a centralized controller for real-time analysis.…”

Distributed power-generation systems (DPGS) contribute significantly to the power generation in modern power systems. Wind and solar photovoltaics (PVs), as representative renewable energy sources, are two major resources for DPGSs. However, owing to their inherent characteristics, the large-scale adoption of DPGSs poses challenges. To resolve these issues and leverage renewable-energy DPGSs, this paper presents DPGS technologies based on wind and solar PVs, as well as their impacts on the distributed grid. Moreover, schemes for enhancing the integration and connection of DPGSs are introduced, and protection issues are discussed in order to increase the robustness of the connection.ABSTRACT | Continuously expanding deployments of distributed power-generation systems (DPGSs) are transforming the conventional centralized power grid into a mixed distributed electrical network. The modern power grid requires flexible energy utilization but presents challenges in the case of a high penetration degree of renewable energy, among which wind and solar photovoltaics are typical sources. The integration level of the DPGS into the grid plays a critical role in developing sustainable and resilient power systems, especially with highly intermittent renewable energy resources. To address the challenging issues and, more importantly, to leverage the energy generation, stringent demands from both utility operators and consumers have been imposed on the DPGS. Furthermore, as the core of energy conversion, numerous power electronic converters employing advanced control techniques have been developed for the DPGS to consolidate the integration. In light of the above, this paper reviews the power-conversion and control technologies used for DPGSs. The impacts of the DPGS on the distributed grid are also examined, and more importantly, strategies for enhancing the connection and protection of the DPGS are discussed.

“…4,5 Adaptive protection schemes are gaining attention as an important part of the integration of complex power distribution systems to overcome new protection, control, and operation challenges, [6][7][8] using adaptive protection schemes in nonradial power systems for microgrids. [9][10][11][12] Adaptive protection is not implemented in radial power distribution systems because fuses are the most popular protective devices installed, and fuses don't have communication and sensing functions to be integrated with backup protective relays. Also, in radial power distribution systems that count with identical fuse ampere ratings at same feeder bus (nontypical scenario), the backup protective relays are set with the same inverse time overcurrent curve, and the implementation of adaptive protection is not required.…”

Summary In traditional power distribution systems, feeder fuses are coordinated with a backup relay without using adaptive protection and sensors. The backup relay is set by selecting the maximum fuse ampere rating and using the relay's resident functions. Because of this, the backup relay is set at the same inverse time‐current curve for all fuses. In this study, to improve the speed and selectivity of the backup relay at busses with different fuse ampere ratings, the backup relay was set at different inverse time‐current curves depending on the maximum ampere rating of the fuses they are connected to. Tests for the adaptive backup overcurrent protection showed how the backup relay selected the settings based on the connected maximum ampere rating fuse, and the relay speed increased up to 32.86%. The backup relay adaptive protection improved the selectivity and speed for clearing the faults, respect to the nonadaptive protection.

“…The different level of microgrid protection schemes which are in the trends discussed as follows, i) Adaptive Protection: In this protection scheme an intelligent electronic devices (IED) are used as protective relay and it can be configured by several settings which correspond to different operating states of the protection system. Adaptive is an on-line protection scheme where the modification for the preferred relay settings can be done in order to provide the response to the system changes [14]. The tripping characteristics (configurations) of numerical relay are well suited for the practical implementation of an adaptive protection system and the standard communication protocol can create the required coordination among the relays.…”

Microgrid is an integrated network of renewable and non renewable resources to supply the green power to a small range of community. An effective communication technology is necessary to be implemented among the power generations, storages and loads of microgrid in order to manage the load sharing, shedding and protection issues. This paper provides the study on architecture, characteristics, load managements, protection schemes, communication techniques and research challenges of microgrid.
