Abstract

With the increasing proportion of renewable energy

the construction of new type power systems had entered a new stage and the demand for enhanced security and stability of power systems induced a strong need for active grid support capabilities and related equipments. This paper systematically introduced photovoltaic-energy storage virtual synchronous generator (PV-ES-VSG) and related systemic technologies. Firstly

the principles and key parameters of PV-ES-VSG were outlined in conjunction with application scenarios

and the topology was proposed by comparing with the current three PV-ES coupling forms. Then

based on different transient and steady-state control objectives

the grid-forming control technologies for PV-ES-VSG and the coordinated PV-ES control strategies were clarified. Core functions such as cluster coordination control and black-start capability were also introduced. Finally

the techno-economic analysis of PV-ES-VSG in typical application scenarios was conducted

and outlooks on technological challenges and future development trends were also provided.
