Article: Architecture and research of photovoltaic hybrid microgrid control system combined with renewable energy Journal: International Journal of Power and Energy Conversion (IJPEC) 2024 Vol.15 No.5 pp.1 - 19 Abstract: The issue of energy supply has become an important social problem, therefore, a photovoltaic hybrid power grid control system is proposed by combining renewable energy to improve the stability of microgrid systems. Based on the operating principles of direct drive wind power systems and photovoltaic power generation systems, a DC voltage source control strategy for wind and photovoltaic hybrid microgrids is proposed, and its effectiveness is verified through experiments. In the dynamic response of the hybrid microgrid during sudden changes in wind speed, the wind speed changes after <i>t</i> = 6s, and the active power of the photovoltaic power generation system decreases from 6,200 W to 5,500 W. Then, the important participating factors of the microgrid system were analysed, and as the trajectory of characteristic value movement changed, the DC voltage parameters of the photovoltaic power generation system were optimised to 2e-3, verifying the effectiveness and practicality of the proposed control system.

Abstract: The issue of energy supply has become an important social problem, therefore, a photovoltaic hybrid power grid control system is proposed by combining renewable energy to improve the stability of microgrid systems. Based on the operating principles of direct drive wind power systems and photovoltaic power generation systems, a DC voltage source control strategy for wind and photovoltaic hybrid microgrids is proposed, and its effectiveness is verified through experiments. In the dynamic response of the hybrid microgrid during sudden changes in wind speed, the wind speed changes after t = 6s, and the active power of the photovoltaic power generation system decreases from 6,200 W to 5,500 W. Then, the important participating factors of the microgrid system were analysed, and as the trajectory of characteristic value movement changed, the DC voltage parameters of the photovoltaic power generation system were optimised to 2e-3, verifying the effectiveness and practicality of the proposed control system.
