Abstract

This paper presents a novel multiobjective control algorithm for standalone PV power systems that can track the maximum power point of the solar array while limiting the charging/discharging current and voltage of the battery under different insolation and load conditions. A state machine model of the multiobjective control algorithm is described. The large-signal stability of the system is analyzed. The controller design is verified by numerical simulation in the virtual test bed (VTB) environment for orbital and land-based applications. Simulation results show that the control strategy is robust and demonstrates that the power converter can be appropriately regulated to meet multiple objectives required by standalone PV power systems.
