1. Abstract
This project presents the concept of fault detection and location in a Power Microgrid
making use of the machine learning concepts like Artificial Neural Network. The electronic
equipment used in microgrids is in essential need of more secure protection against short
circuit faults. Due to the high current at the time of fault occurrence, the whole system
might be de-energized which would have a severely negative impact on the entire system. A
fault occurs when two or more conductors come in contact with each other or ground.
Ground faults are considered as one of the main problems in power systems and account
for more than 80% of all faults. An effective method to detect, isolate, and protect the
power microgrid system against the effects of short circuit faults is extremely important. In
this project we worked on a highly effective new method to protect the microgrid system
using an Artificial Neural Network (ANN) that will detect and find the location of the fault
before it affects other parts of the system. It would, therefore, be more dependable for
microgrid protection. This protection network is distributed all along the power microgrid
system protecting the entire microgrid network and is connected to the other protective
devices in the system.
This project focuses on detecting faults and identifying the location of the faults on electric
power transmission lines in the power microgrid network.

2. Introduction
The expansion of renewable energy sources has been a concern in recent years. Even
though these conventional energy systems are appropriate substitutions for old power
systems, disadvantages and difficulties in power generation and distribution such as
overvoltage, fault protection and frequency fluctuations are barriers that should be solved
as well.
The future electricity network will need to accommodate large scale of distributed
generation units (DGs) and facilitate the connection of grand scale of centralized generation
at suitable locations. Microgrid has been considered as an effective way to manage the DGs
and other distributed energy resources (DERs) on the distribution system level and the user
level. Microgrids provide efficient, low cost and clean energy. These are critical
infrastructure that increases reliability and resilience.Also reduce grid “congestion” and
peak loads. Still, the protection of these microgrids remains a problematic issue. When a
fault occurs in the system, it creates a huge current that could affect the entire system
working, and it could stop the whole system. The possibility of locating faults quickly and
isolating that part from the other parts of the system would allow the rest of the power
microgrid to continue working.
