Abstract

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.
