Abstract
The substantial increase in the proportion of renewable energy power generation has put forward higher requirements and challenges for the dispatch of the power system. Recently, there is a lack of a complete evaluation system for the dispatching results of power systems with a high proportion of renewable energy, which leads to the lack of feedback and improvement links after the implementation of the dispatching strategy. This paper takes the dispatching results of power systems with a high proportion of renewable energy under four different dispatching modes as the evaluation object, and constructs an evaluation index system including four dimensions of environmental protection, economy, safety and fairness. And a comprehensive evaluation model and evaluation method based on Pythagorean fuzzy set (PFS) and TOPSIS (Technique for Order Preference by Similarity to ideal Solution) are presented, which were verified with the calculating examples.
