“…Optimal coordination adjustments have been determined for an adaptive protective scheme before its physical implementation. Tests performed with real-time (RTS) and non-real-time simulation (NRTS) has been also compared [120], validating the selectivity, reliability and speed for the adaptive overcurrent protection systems.…”

This paper reviews and discusses the use of adaptive protections in microgrids. The main goal of the paper is to review the progress made in the last 10 years, to identify the challenges that are still present, and to note the current trends in the use of these protections in microgrids. The analysis is based on applications implemented since 2007, and on a wide bibliographical review of books, theses, patents, scholarly papers, conferences, technical reports, and experts' experiences. The paper includes a comparative table that summarizes the reviewed literature and its findings. The paper is of interest to academics who do research on development and implementation of new robust and reliable protection schemes in microgrids, and to those in the industrial sector, who implement electric microgrids, and who want to understand the impact of their protection schemes.

This paper reviews protection schemes for meshed distribution networks. It gives emphasis to the increasing penetration of electric vehicles, their charging patterns, and to the increasing value of distributed generators, especially from renewables. It includes a preliminary analysis on system planning with electric vehicles that is studied probabilistically and a more detailed analysis of the expected changes introduced by these new loads. Finally, a real time hardware-in-the-loop review analysis for protection systems and the open source networks available for protection studies from several sources are also provided. This work could be useful as a collective review of the recent bibliography on protection for meshed networks, giving emphasis to electric vehicles and their real time simulation.

Integration of DC circuit breaker and fault current limiter based on zero‐voltage resonant switching approach

It is known that most of the renewable energy resources are the DC type. However, DC microgrids do not have zero crossing in current and voltage. This results in serious concerns about the circuit breaking and fault current limiting in the power system. Conventional thyristor-based DC fault current limiters (FCLs) may provide possible solutions for this problem. Unfortunately, a permanent interruption would arise on the system in case of a temporary fault. For this reason, this proposal aims to develop an integration system of the circuit breaker and FCL using a feedback-controlled zero-voltage switching method. In this proposed model, a load current is detected and an appropriate switch signal is thus generated by the controller based on the feedback-control strategy. Once the load current is beyond the predefined value, the switch will be opened to reduce the current immediately for a period of time set by the timer in advance. Then, the switch will be closed again to raise the current continuously until the overload threshold is reached. The switching transition duration is located at the resonant zero voltage, so that no switching power is required. Both simulation and practical performance results confirm that an expected constant load current can be well controlled over an expected range.
