Power System State Identification Based on Set Theory Estimation Part Two Solving Method Based on Interval Constraints Propagation
摘要
Abstract
The state identification model with only bounded errors is a typical constraints satisfaction problem,and variables and constraints can all be presented in the form of intervals.Thus,interval analysis can be adopted to solve this constraints satisfaction problem.The conventional interval constraints propagation method is first proposed to solve this model.However, the results are locally consistent and have conservative character to a large extent.To deal with this problem,the improved interval constraints propagation method is proposed.On one hand,monotonicity is introduced to an interval constraints propagation algorithm,which can effectively eliminate the conservative character resulting from the many times”appearance of monotone variables.On the other hand,by increasing redundant constraints,the original constraint sets are extended,which can eliminate the conservative character resulting from the local consistency of interval constraints propagation algorithm to a great extent.关键词
