Is electrical engineering a multidisciplinary field?

Electrical engineering does not exist in isolation, and most of the big technological challenges we humans face will require “multidisciplinary” solutions that will span more than one specialty. The link in Kay Robinson’s answer is a good one, as it discusses engineering challenges in general, not limited to any one field.

What is electrical engineering?

Electrical engineering is a broad field right from Electrical Power Generation to Distribution to end users. With deep penetration of Power Electronic Devices (PED) into electrical system, it has become complex to understand and control, but has given many advantages.

What is computer engineering?

Computer engineering is also an integrated branch of several fields of engineering like electrical and computers, which focuses on programming, and integration with hardware devices. Electrical engineering is always a challenging field which requires a regular up keeping with proper control and communication system.

What are the challenges of microgrids?

Today's electrical power system is facing a number of challenges which includes age old equipment, continuous growing demand, demand for electrification of remote areas and conservation of natural resources. Microgrid is one of the solution for these challenges which meets the local demands through Distributed Generations and is parallel with utility grids if exists. There are certain technical and regulatory issues to be considered in Microgrid systems. One of the major technical issues will be of electrical protection which needs to be analysed in Microgrids. The protection issues of microgrid are case studied in this paper including simulation with a software and a conclusion is arrived.
