Assessment of Power Quality Improvement Potential of New Power Grid Based on(p,q)-Rung Interval-Valued Orthopair Fuzzy Number and Relative off-Target Distance
摘要
Abstract
[Objective]Under the context of large-scale renewable energy integration,it is crucial to quantitatively assess the power quality improvement potential of power grid for subsequent governance services and ensuring efficient and stable operation of the power grid.[Methods]Therefore,an assessment method for power quality improvement potential of power grid based on the-rung interval-valued orthopair fuzzy number and relative off-target distance is proposed.First,a comprehensive evaluation index system is constructed around four dimensions:power quality,power supply reliability,serviceability,and low-carbon.The fuzzy analytic hierarchy process method based on the-rung interval-valued orthopair fuzzy power weighted average operator is adopted to subjectively weight primary indicators,and the improved criteria importance through the intercriteria correlation method is used to objectively weigh secondary indicators.The final weights are obtained through linear weighting.Second,the technique for order preference by similarity to an ideal solution and Mahalanobis distance are introduced to establish an improved grey target decision-making model based on positive and negative target centers,and the power quality improvement potential is quantitatively analyzed using the relative off-target distance.Finally,case studies are conducted on five typical regions in a certain city.[Results]The results show that the higher the relative off-target distance,the better the level of power quality and the smaller the improvement potential.Analysis of the relative off-target distance for a single area can effectively identify the core factors that affect improvement potential.[Conclusions]The proposed model and method can analyze the impact of multidimensional factors on the improvement in power quality of regional power grid,accurately assess the overall situation of power quality,and help to improve power quality problems in a targeted manner.关键词
