We investigate a real time (RT) communication and control technique for a user centric stand-alone distributed photovoltaic (PV) system. The current user centric RT techniques for grid-connected systems may not be directly employed in stand- alone systems due to contradiction in their objectives. In this paper, we propose a user centric RT control algorithm for stand-alone PV systems and investigate its communication requirements. Our aim is to minimize an average aggregate system cost considering a joint optimization problem of load scheduling, energy procurement from a peak generator (PG) and battery energy storage (BES) management. By subsequent relaxation and reformulation of the problem, we employ the Lyapunov optimization technique (LOT). Simulation results show the effectiveness of the proposed RT solution in terms of the selected performance metrics.
