Protective Systems in DC Microgrids
2019The aging power system causes to several grid problems such as intermittency, power quality issues, and blackouts since a few decades. Therefore, the power infrastructure requires serious troubleshooting studies in a wide manner. The distributed generation and integration of large photovoltaic (PV) plants to the existing utility have led to intensive ...

Adaptive Protection for Preserving Microgrid Security
IEEE Transactions on Smart Grid, 2019The low inertia renders renewable-based microgrids ( $\mu$ Gs) more susceptible to incipient faults and makes it more difficult for distributed systems to maintain a reasonable margin for dynamic security. This paper studies the $\mu\text{G}$ security using a three-stage approach to the power system protection.

Protection Coordination in AC Microgrid via Novel Voltage-Supervised Directional Over-Current Relays
IEEE Transactions on Power DeliveryConventional protection schemes are susceptible to dynamic changes in AC microgrids having diverse Distributed Generators (DGs). These changes, caused by different DG types, significantly alter the fault current levels, leading to conventional ...

Microgrid Protection and Automations
2019After the decision on devolution of electric power generation, a great number of dispersed storage and generation (DSG) units, which is mainly driven by renewable energy sources, has been connected to the power distribution networks. Existing of DSG units in the distribution network has converted the traditional distribution systems into active ...

Novel Grounding and Protection Strategy for DC Microgrid Restraining Fault Current
IEEE Transactions on Power DeliveryThe dc microgrid affirms its prominent presence by optimally exploring distributed generations' benefits and reducing greenhouse emissions. The absence of effective protection and grounding solutions limits the broad adoption of dc microgrids.
