The atmosphere near the ground surface is affected more than the ionospheric region in terms of ionization by the electromagnetic emissions caused by various reasons. One such occurrence is the emission of radon (Rn222) from lithosphere through the deformities of the earth crust during the earthquakes. This creates atmospheric anomalies before any strong seismic activities which seem to be present in the meteorological parameters. The evidence for atmospheric anomalies has yet to be meticulously analysed. The data for analysis can be recorded by receiving through L-type antenna and a detector module having a local oscillator, power amplifier, IF amplifier and data acquisition card. But in this work, the data are satellite data. Here, the event of Indonesia earthquake occurred on 6 December 2016 with magnitude Mw 6.5 analysed for observing the anomalies in meteorological parameters, viz. air temperature, relative humidity, atmospheric pressure and wind speed before and after this earthquake. The variations of these parameters might help to predict the occurrence of the earthquake 2–3 days prior to its occurrence. We obtain certain anomalies in temperature, relative humidity, pressure and wind speed observations. Also, we have found that 30-km depth is very sensitive for Indonesia. © 2020, Springer Nature Singapore Pte Ltd.

Decentralization of electric power is possible with the penetration of distributed generators (DGs) in the microgrid (MG) network. Reconfiguration of MG poses a key challenge in identifying suitable protection schemes for varying the topology of the network. In this paper, a central protection center (CPC) is incorporated whose function is to monitor the MG continuously, identify fault occurrence, and locate the exact faulted branch. The proposed Prim-aided Dijkstra algorithm executed continuously in the CPC is responsible for identifying the current topology of the network and aids in identifying the shortest route from the faulted point to the nearest operating source. The CPC is also responsible for adaptively varying the settings of the relays existing in the shortest path identified based on their selectivity levels. This heuristic algorithm is validated on IEEE 21-bus and 40-bus MG test systems for all possible topologies and faults. The proposed algorithm is capable of clearing the fault by disconnecting minimum portion of the network and ensuring continuity of supply to a majority of loads. © 2013 IEEE.

Prims-Aided Dijkstra Algorithm for Adaptive Protection in Microgrids

Microgrid caters to the growing power demand in the distribution network. Due to reconfiguration of microgrid, conventional protection schemes are not suitable for fault clearance. This paper proposes a communication assisted central protection system (CPS), which monitors the microgrid. The active nodes of the network are populated using Bellman Ford algorithm. In the event of fault, the Dijkstras algorithm is employed on the current topology of network, to identify the shortest path from the faulted point to the point of common coupling. This hybrid algorithm ensures that during fault clearance, minimum portion of network disconnection occurs. The algorithm is tested and validated on 40-bus and 54-bus microgrid network. © 2016 American Scientific Publishers. All rights reserved.

Shortest Path Identification in Reconfigurable Microgrid Using Hybrid Bellman Ford-Dijkstra’s Algorithm

An intelligent micro grid controller system with over current protection capability in both the grid-connected and the islanded modes of operation is proposed. To achieve the above strategy a model of small portion of distribution network as if it were a micro grid will be developed and considered. The processor based relays that provide over current protection functions in addition to performing control, measurement, and communication functions will be suitably employed. © 2015 IEEE.
