Integrated Dispatching of Wind-PV-hydro-storage Considering Equivalent Energy Storage Effect of UHVDC Transmission
摘要
Abstract
To address the issue that the storage capacity of a wind-PV-hydro-storage integrated base at present cannot fully smooth the fluctuations of output from renewable energy,an optimization strategy for a multi-region wind-PV-hy-dro-storage integrated base is proposed,which takes into account the equivalent energy storage effect of ultra high volt-age direct current(UHVDC)transmission channels.Under this strategy,the complementary benefits of output from re-newable energy in different regions are considered comprehensively,and the advantages of flexible control of UHVDC transmission channels are combined to bring the equivalent energy storage effect of UHVDC transmission into full play.The goal is to reduce the reliance on physical energy storage,minimize the system's total operating costs and alleviate the peak-shaving pressure on the grid.Simulation results show that with the consideration of the energy storage effect of UHVDC transmission lines,the optimized multi-region multi-energy complementary coordination operating mode im-proves the resource utilization efficiency of the wind-PV-hydro-storage integrated base to some extent,expands the equivalent storage capacity and enhances the transmission flexibility.关键词
