摘要：
In order to solve the problem of voltage instability under the influence of the increasing proportion of new energy and external DC power in the receiving-end power grid，and further realize the rationality of the receiving-end power grid planning，this paper proposes a planning model for new energy receiving-end power grid considering dynamic voltage stability. Firstly，based on the improved small signal analysis method，the dynamic voltage stability model of the new energy receiving-end power grid is established. Then，considering the uncertainty of wind power，photovoltaic and load，with the goal of minimizing the total planning cost，this paper establishes the planning model for new energy receiving-end power grid considering dynamic voltage stability，and solves it. Finally，the simulation results show that the new energy receiving-end power grid planning model proposed in this paper can improve the receiving-end power grid's ability to accept the uncertainty of future new energy and load，and effectively reduce the risk of dynamic voltage instability of receiving-end power grid. © 2024 Science Press.
