Modeling & designing of smart energy meter for smart grid applications

Privatization of the power sector has nearly closed the monopoly in the electricity market and enhanced competition among different power companies. This leads to the development of automation in power systems. Innovation tends to implementation of a new concept of smart meters in the smart grid. Conventional grid is facing power losses in distribution sector with an increase in losses leads to an increase in per-unit cost of electricity. A new concept of renewable energy in the smart grid comes into the picture while taking into consideration of reduction in carbon footprints. The smart meter is uncomplicated to handle and supply on-time details of utilization of energy and its price. It lowers energy demand by ensuring proactive utilization of electrical energy and reducing carbon emissions. Substitution of conventional energy meters with intelligent meters not only implements smart technology but helps in the mutual benefits of utility companies and consumers. The concept of Advance metering infrastructure replaces by automatic meter reading. Installation of an intelligent meter is the first step in the nation to implement smart metering. Keeping in view about losses such as tampering, malicious activities by a consumer, delay in billing leads to enhancement of compulsory smart meters policy in the entire nation. In this paper mathematical modeling of single-phase smart energy meter being presented and estimation of both power and energy in terms of active, reactive, and apparent by energy computation chip. Simulation of single-phase intelligent meter is performed on Proteus simulator and its results are presented.
