Based on various intelligent technologies, smart grids can effectively ensure voltage stability, achieve large-scale and cross regional power dispatching, and make power resource allocation more reasonable. However, with the continuous integration of various emerging energy sources, the voltage regulation in smart grids faces more complex and ever-changing external environments. The stability control of voltage regulation is challenged. To enhance voltage regulation in smart grids, this study proposes a model based on the three-state energy (TSE) structure. A Markov game (MG) model is introduced to perform regional calculations on the smart grid. A distributed calculation method for voltage regulation in the smart grid is constructed. The experimental results showed that the IAE, ISE, ITAE, ITMSE, ISTAE, and ISTSE of the voltage regulation method were 0.0051, 0.0056, 0.027, 0.0024, 5.57, and 0.00468, respectively. All error integration criteria are lower than other commonly used voltage regulation methods. The research results have important reference significance for effectively implementing voltage control in smart grids, optimising voltage control methods, and improving the stability and reliability of power supply.
