Optimal Power Flow in Active Distribution Networks with On-load Tap Changer Based on Second-order Cone Programming
摘要
Abstract
With increasing distribution generation resources integrated,the power distribution network has become an active distribution network(ADN) with definite controllability and its optimal operation is essentially an optimal power flow (OPF) problem with various discrete controllable devices.However,owing to the nonconvexity and nonlinearity of the model,a highly efficient method of solving this kind of problem is the focus of this area.Since the on-load tap changer (OLTC) is an important controllable device in ADN,its strategy has a significant influence on power system operation,especially at the voltage level.Therefore,developing highly efficient methods to solve OPF problems in ADN with OLTC is exceedingly necessary.Based on the branch flow model,an OPF model with OLTC in ADN is developed.An exact linearization modeling method for OLTC using piecewise linear technique is proposed,and the applicability of a second-order cone relaxation method for solving the corresponding OPF problem is demonstrated.A case study based on the modified IEEE system shows the effectiveness of the proposed modeling method of OLTC and the high efficiency of the second-order cone relaxation method in solving the OPF problem in ADN with OLTC.关键词
