Smart metering in micro-grid applications

With continuous technology development in power grid from utilities and micro-grid from residential and commercial buildings, smart metering plays an important role to monitor the performance and the energy usage of the grid loadings and power quality. The main difference of smart meters between power grid and micro-grid are tamper detection, form factor and billing purpose. In micro-grid, smart meters provided by developers are for internal use only. In this paper, the authors try to evaluate the application benefits from different angle of smart metering in micro-grid (ie. electrical distribution in building).
