Abstract

In this paper, a novel distributed control strategy addressing a (feasible) psycho-social-physical welfare problem in islanded Direct Current (DC) smart grids is proposed. Firstly, we formulate a (convex) optimization problem that allows prosumers to share current with each other, taking into account the technical and physical aspects and constraints of the grid (e.g., stability, safety), as well as psycho-social factors (i.e., prosumers’ personal values). Secondly, we design a controller whose (unforced) dynamics represent the continuous time primal-dual dynamics of the considered optimization problem. Thirdly, a passive interconnection between the physical grid and the controller is presented. Global asymptotic convergence of the closed-loop system to the desired steady-state is proved and simulations based on collected data on psycho-social aspects illustrate and confirm the theoretical results.

Abstract

In this paper, a novel distributed control strategy addressing a (feasible) social-physical welfare problem in Direct Current (DC) smart grids is proposed, which is based on physical, technical and social aspects of the grid. Firstly, we formulate a (convex) optimization problem that allows prosumers to share power - and the financial and psycho-social costs and benefits associated with the generation and consumption of power - with each other, taking into account the technical, physical and social aspects and constraints of the grid (e.g., stability, safety, user preferences). Secondly, we design a controller whose (unforced) dynamics represent the continuous time primal-dual dynamics of the considered optimization problem. Thirdly, a passive interconnection between the physical grid and the controller is presented. Global asymptotic convergence of the closed-loop system to the desired steady-state is proved and simulations illustrate and confirm the theoretical results.
