Generally, smart grids technologies can be put into four functional categories: Information collectors; information assemblers, displayers, and assessors; information-based controllers and energy resources. Smart grids collected data from various types of sensors. These sensors measure performance-related characteristics of electricity system components. Assessors are used to analysis and display the information they received from the devices. The information-based controllers devices will use the information that they received to control the other devices behavior to achieve the goal. Energy or power resources include the technologies that can used to generate, store, or reduce demand for electricity.

However, renewable energy sources have been used in so many countries to reduce CO2 emissions and provide sustainable electrical power. The power electronic interface between a renewable energy source and the grid can be used to control reactive power output and hence the network voltage as well as curtailing real power output, and so enable the generator to respond to the requirements of the grid.

Advanced metering infrastructure (AMI) is one of the smart grid technologies that have been used in many homes and business. Their objective is to enable to let the users can use wattage readers to check how much juice their appliances and gadgets use. They measure energy usage with less than one-hour intervals, communicate usage data back to the utility regularly like up to
