To meet the future economic growth and the societal need, it is becoming apparent that the current power grid needs to be modernised to make it more reliable, flexible, efficient, and resilient. That leads to the concept of the smart grid; a controlled electrical grid that connects diverse power generation resources, transmission, and distribution, using sensor, communication, and control technologies. Major paradigm shifts in the power grid include integration of distributed generators with variable outputs, and two-way power flow to allow electricity generation in real-time based on consumer demands and power requests. However, there are many obstacles in implementing the smart grid vision.
