China's new energy power stations generally have power-limiting phenomena. How to participate in the scheduling of multiple new energy power plants under limited power conditions becomes a key issue. This paper proposes a new energy power plant coordinated scheduling method considering the fairness of new energy power generation. Firstly, the evaluation index system of new energy power stations is proposed considering the technical, operational characteristics, economy and reliability. Secondly, a comprehensive evaluation method of new energy power station evaluation index system based on grey relational degree and entropy weight method is proposed to evaluate the advancement of new energy power station. Thirdly, based on the comprehensive ranking of new energy power plants, a coordinated dispatching model is established to minimize the generation cost of power system with new energy. Finally, an example shows that the proposed evaluation index system and its analysis method can correctly evaluate the advanced nature of new energy power plants, and the proposed coordinated scheduling model can effectively guarantee the priority of power generation with comprehensive ranking power stations and enhance the fairness of new energy power plants participating in dispatching.
