Comprehensive evaluation index system of generation planning based on gray correlation degree and evidence theory

In order to make a comprehensive and effective evaluation of power supply planning, this paper proposes a method for establishing a comprehensive evaluation index system of power supply planning based on grey correlation theory and evidence theory. The index system is divided into four aspects: reliability, security, economy and environmental factors. Using the method combined gray theory with evidence theory, it is realized the combination of the objective gray theory with subjective experience of experts so that its correctness and reasonable are guaranteed. And then, a comprehensive evaluation of cloud model is established based on index weight set, norms set and degree of membership matrix. This method is validated by a simulation example, which combined a comprehensive evaluation index system of generation planning with a comprehensive evaluation of cloud mode. This program provides a complete set of evaluation programs for generation planning comprehensive decision-making. © 2020, Solar Energy Periodical Office Co., Ltd. All right reserved.
