| Abstract: |
| In order to reduce the negative impact of grid-connection of wind and photovoltaic power stations(WPPSs) on the voltage stability of power system, a coordinated siting and sizing planning method of WPPSs considering static voltage stability is proposed. The power generation characteristics of WPPSs are analyzed and their mathematical models are established. Considering the internal restriction relationship between equivalent grid-connected impedance and static voltage stability, the coordinated siting and sizing planning model of WPPSs is established by synthesizing optimization objectives such as siting and sizing of WPPSs and their collection stations, grid-connected point, and so on. Based on the map rasterization and piecewise linearization mthods, the proposed planning model is transformed into a mixed integer linear programming model. On this basis, K-means algorithm is used to extract typical scenes and the solution process of the proposed model is given. Based on the actual data of a region in Southwest China, the simulative results show that the proposed planning method can give full play to the natural resource endowment characteristics in the planning region and the complementarity of wind and photovoltaic power, and effectively improve the static voltage stability of the system with grid-connected WPPSs. |
