Abstract
To address the challenges posed by the large-scale integration of electric vehicles and new energy sources on the stability of power system operations and the efficient utilization of new energy,the integrated photovoltaic-energy storage-charging model emerges.The synergistic interaction mechanisms and optimized control strategies among its individual units have also become key issues urgently needing resolution in smart grid development.Due to the characteristics of integrated generation,load,and storage,mutual complementarity of supply and demand,and flexible dispatch,the photovoltaic-energy storage-charging(PV-ESS-EV)integrated station micro-grid(ISM)mode,incorporating"PV-PV-ESS-EV + intelligent building"features,has become a focal point for energy conservation,carbon reduction,and energy transition in China.In consideration of the challenges faced by the operational mode of microgrids,such as the strong uncertainty of distributed energy sources and the unclear interaction mechanisms during islanded and grid-connected operation,various aspects of the PV-ESS-EV ISM are reviewed,including its unit modules,key technologies,and operational states.Additionally,the current research status of PV-ESS-EV is summarized while future development trends are discussed,and the challenges that need to be addressed are examined.The research findings have important theoretical and practical implications for exploring the regulatory potential of various demand-response resources under economic incentives,ensuring the reliability of power grid supply,and serving as valuable references for both theory and practice.
