Abstract: The traditional electrical power grid used to be one-directional power flows (flowing from producers to consumers). Nowadays, the consumers become more active and they participate in electricity generation process through Demand Response (DR) actions applied on their electrical loads. As result, power flows become more and more multi-directional and production units more decentralized. Electrical grid architectures must be developed in parallel in order to meet these increasing changes that lead to what is known to be Smart Grids. In this paper, we first present a literature review about the smart grid architectures and the various associated models. Then, we propose a closed loop supply chain approach to model and optimize configurations and operations of smart grid systems. Within this context, a whole section is devoted to the development of a mixed nonlinear programming model to optimize the architecture of given smart grid systems. For illustrative purposes, using a specific smart grid system and appropriate data, we model the problem and solve it for the optimal architecture.

Keywords: Smart grid architecture, closed loop supply chain, mathematical model and optimization
