Power system restoration based on intentional islanding of microgrids in disaster management using Artificial Neural Networks (ANN)
Authors
Abstract
The Power outages that last for weeks at a time are a result of natural
disasters with an extensive influence on electrical networks. To regain power, it is
difficult to suppress these effects. Researchers presented an assortment of methods for
power restoration using distributed energy resources (DERs). DERs can be produced by
using power devices, batteries, diesel generators as well as different sources of renewable
energy. The valued distribution system requires DC voltage with low voltage, direct
current which also can be delivered by DERs. In proposed research, an effort is taken to
restore electricity in the wake of disasters based on deliberate islanding in intelligent
architecture, called Artificial Neural Networks (ANN). Traditional power system
restoration methods encounter stability issues because renewable DERs operate in an
unanticipated manner. Our study highlights the value of intentionally isolating microgrids
as a strategy to speed up and stabilize the restoration process. Segmenting the grid allows
for the systematic identification and repair of distressed areas while preserving intact
portions. This technique reduces the likelihood of further system failures while
streamlining the restoration procedure. In the final analysis, compared to an islanding
algorithm, the use of ANNs significantly reduced model execution times throughout the
restoration process and improved stability. The output of a MATLAB simulation shows
the effectiveness of the DER and its control strategy to improve dynamical stability.
