OPTIMIZATION AND EVALUATION METHOD FOR DELIVERY POWER OF WIND POWER WITH TARGET OF REDUCING POWER LOSS UNDER MULTI-CONSTRAINT CONDITIONS

摘要

The invention discloses an optimization and evaluation method for deliverypower ofwind power with a target of reducing power loss under multi-constraintcondition,comprising the following steps of: confirming the factor aggregation Uaffecting thepower loss of a wind power system, computing the influencing characteristic ofeach factorto the power loss, forming a hierarchical model comprising a scheme level anda factorlevel, dividing U into an immutable factor aggregation UN and a variablefactoraggregation Uc according to the operation mode of the wind power system,confirmingthe priority matrix W of Uc by a dispatching operator, preliminarily screeningandobtaining multiple feasible schemes according to the variation characteristicof the powerloss of the wind power system with each factor and UN , setting up amembership matrixR of the factor level and a membership matrix S of the scheme level accordingto Wand multiple feasible schemes, computing the priority N of each feasiblescheme inmultiple feasible schemes according to a preset comment set and S , andselecting thefeasible scheme with the greatest priority as the optimal scheme. The methodcanovercome the defect that the prior art cannot synthesize multiple factors toconductquantitative evaluation and has high power loss, etc; and the method has theadvantages ofsynthesizing multiple factors to conduct quantitative evaluation and reducingthe powerloss.
