China accounts for about one-third of global carbon dioxide emissions and one-quarter of greenhouse gas emissions (Wang et al., 2020; Zhou et al., 2021).Undoubtedly, China plays a crucial role in promoting global net-zero emissions, and the development of clean energy and efficient energy conversion is key (Wei et al., 2021; Li et al., 2022).
Grid integration of solar photovoltaic (PV) systems has been escalating in recent years, with two main motivations: reducing greenhouse gas emission and minimizing energy cost. However, the intermittent nature of solar PV generated power can significantly affect the grid voltage stability. Therefore, intermittent solar PV power generation and uncertainties associated with load

Distributed Energy Resources (DER) have been increasing significantly around the world, but they create many integration challenges, since their output can be uncertain. As a result, short-duration voltage variations throughout distribution systems with high level of DER penetration may become more frequent, thus novel voltage regulation strategies are going to be decisive in allowing a
Ubiquitous energy storage and grid forming will ensure the long-term stability of new power systems. As an important power supply that supports the power grid, an energy storage system (ESS) plays a key role in the power generation, transmission, distribution, and consumption of a new power system. The grid-forming ESS implements stable control
