FAIRNESS INDEX OF EFFICIENT ENERGY ALLOCATION SCHEMES IN A TREE BASED SMART GRID

Abstract

Smart power distribution is a challenging task in a power grid as demand from the end users connected to the grid varies dynamically. Energy allocation should be done optimally among the commercial and domestic users which have varied energy consumption and pricing rates. Important aspects such as user demand and fairness among users can be considered for efficient energy allocation in smart grid. In this work, we have proposed and analyzed energy allocation strategies for satisfying maximum number of users, maximizing the profit, minimizing average slots per user, maximizing average slots per user and maximizing the number of users while maximizing the profit in a smart grid tree network. Parameters, such as, total energy cost, number of active users and fairness index are incorporated in our proposed schemes and our schemes are compared with existing schemes, such as, Round Robin and Priority based schemes. Extensive simulation studies have been carried out to show the efficacy of the proposed approaches.
