Research on Optimal Allocation Method of Wind-Solar-Thermal Integration Power Base

The-wind-solar-thermal integration (WSTI) power base is an important technical mean to achieve carbon emission peak in China. A new optimal allocation model for the existing thermal power is given in this paper with the optimization target of maximum of new energy generation. In order not to increase the peak shaving pressure of power system, the additional regulation capacity of thermal power is used to bundle new energy resources, and the constraint of source-load similarity is intrduced for the first time. The source-load similarity is evaluated from two dimensions, namely fluctuation index and similarity index. The intelligent optimization algorithm is taken to solve the model. The proposed method can increase the electrcity production of new energy and efficiency of electric transmission line. Finally, an optimization model is built, and the simulation results prove the effectiveness of the proposed method.
