A Load Power Sharing Strategy for Virtual Oscillator-based Photovoltaics Generation in Islanded Microgrid

IFAC-PapersOnLine, vol. 53, pp. 12906–12911

Abstract

This paper proposes a method to control the power-sharing between parallel-connected photovoltaics generation in an islanded microgrid. The two-stage converter-based PV generation is used combined with modified virtual oscillator control and cascade sliding mode control. With this proposed control configuration, the power-sharing in proportion to the inverter power rating and maximum power point tracking is guaranteed autonomously without the need of energy storage systems, while maintaining the primary advantages of the virtual oscillator control method. The effectiveness of the proposed control scheme is validated through simulations in MATLAB/Simulink.
