DG Penetration Rate Planning for Active Distribution Network Based on S-OPF
Active distribution network (ADN) is an indispensable part of smart distribution network under smart grid framework.Based on the study of vaarious integration modes,an economy optimal model of DG penetration rate plan from a DSO perspective is proposed and two DG integration indexes are defined,namely integration ratio and GC ratio.The hourly sequential model is adopted to simulate load and DG uncertainties and a method of DG optimal plan based on stochastic optimal power flow (S-OPF) is presented.Monte Carlo simulation is used in stochastic power flow.Combined with usual connection mode of Shanghai distribution network,a 48 bus test system is built for ADN research in Shanghai.The influence of integration indexes on economy in two scenarios is analyzed and some useful conclusions are achieved.
