VDAPF Optimization Configuration Strategy of Distributed Harmonic Control in Digital Active Distribution Grid

基于数字化配电网分布式谐波治理方案,考虑多功能并网逆变器(MFGTI)的辅助谐波治理功能,提出一种计及MFGTI贡献的电压检测型有源电力滤波器(VDAPF)优化配置策略。首先,介绍VDAPF和MFGTI协同谐波治理分区方法,确定VDAPF最佳安装位置;其次,利用场景分析法构建谐波和MFGTI的双重不确定性;然后,构建多目标的VDAPF容量优化配置模型,同时兼顾经济性和治理效果,利用规格化法平面约束(NNC)将多目标模型转化为单目标模型进行求解;最后,以IEEE33节点配电系统为例进行仿真验证。结果表明在VDAPF配置中考虑MFGTI的治理功能,可达到更好的经济性和治理效果,验证了所提策略的有效性。

Based on the distributed harmonic control scheme of digital distribution network, considering the auxiliary harmonic control function of multi-functional grid-tied inverter(MFGTI),An optimal configuration strategy of Voltage Detection Active Power Filter(VDAPF) considering the contribution of MFGTI is proposed.Firstly, the VDAPF and MFGTI coordinated harmonic control zoning method is introduced to determine the best installation location of VDAPF.Secondly, the dual uncertainties of harmonics and MFGTI are constructed by using scenario analysis.Then, a multi-objective VDAPF capacity optimal allocation model is built, and both economic and governance effects are taken into account.Normalized Normal Constraint(NNC) is used to transform the multi-objective model into a single objective model for solution.Finally, an IEEE33 node distribution system is taken as an example for simulation verification.The results show that considering the governance function of MFGTI in the configuration of VDAPF can achieve better economic and governance effects, and the effectiveness of the proposed strategy is verified.
