Study on wind power integration optimization model suitable for multi-operation mode

In day-ahead and real-time phases, due to limited regulation generation resources to satisfy operation reserve requirement, it is difficult to guarantee clean energy integration in full, and the integration capacity of power grid to clean energy could not be fully realized. Meanwhile, in the monthly and long-term operational planning phase, on the basis of power plant annual plans and future trend analysis for electricity, there are more generation resource optimization tools. Through different time cycle, power generation and transmission resources coordination optimization, the level of integration for clean energy can be improved. In this article, optimization periods and power-power conversion method are analyzed. The wind power integration optimization model for the three operations modes “clean energy full integration, system run cost minimum, SAN-GONG progress deviation minimum” are respectively established. Based on sequential multi-objective optimization method, the wind power monthly integration optimization model that gives consideration to multi-operation mode is proposed. The proposed model was tested on a real system; the results obtained demonstrate the effectiveness of the model.
