基于下垂控制的微电网DG选址和功率分配方法研究
Research on DG location selection and power sharing method of sag control microgrid based on MILP
摘要
Abstract
Reactive power sharing among distributed generators(DG)is a key problem in droop control based microgrid operation.The causes of unequal reactive power sharing include feed impedance differences,load differences,and uneven distribution of DG in size and position.Therefore,a mixed-integer linear programming(MILP)problem for microgrids is presented to achieve proportional reactive power sharing among microgrids.Firstly,the optimum size and position of DG are studied,and various nonlinear terms involved are linearized in detail.Then a one-day advance schedule is generated on these DGs for a given load profile.After that,an actual ZIP load model is used to model the load more accurately.Finally,the proposed method is tested on a modified 33-bus network.The experimental results verify the accuracy of the proposed planning and scheduling methods.关键词
