| Summary: | With the rapid increase in the installed capacities of wind power and PV power in China, large-scale new energy integration has received wide attention. An evaluation method for multi-area large-scale new energy integration capability is proposed in this paper. The steady-state security region (SSSR) of a power system is defined in the multi-area new energy power injection space. According to the regional and resource characteristics of the large-scale new energy station access, a group of power growth directions is defined for each region, and a mathematical optimization model of new energy integration capability is built in one-dimension space. The optimal power flow traverses the new energy power growth directions of the whole system composed of different regions to search for the critical points of SSSR. Based on these critical points, a hyperplane is constructed to approximate the SSSR boundary of multi-area new energy power injection space, so as to evaluate the multi-area large-scale new energy integration capability in multi-dimensional space. Numerical results of a provincial 1975-bus system are presented, proving that the proposed model is practical and effective. |
