A new approach of generating scheduling in power system with wind power using electrical paths between generators and loads

摘要

Due to wind powerfluctuation, it is difficult to make generating schedule of power system with wind power.rnThis paper presents a new approach to make generating schedule using electrical relationships betweenrngenerators and loads. A two-layer structure is used in the approach, i.e. generating schedule is made andrnrevised in on-line time scale in upper layer, and automatic generating control (AGC) is carried out inrnreal-time time scale in lower layer. Both generating schedule-making and AGC are implemented usingrnpower transmission factors among wind farms, related traditional generators and loads. And generatingrnschedule is revised taking the operation limit of generators and transmission congestion into consideration.rnAt last, the technical and economic benefits are analyzed in case study. The results show that the approachrncan effectively trackfluctuation and forecasting error of wind power and enhance the operation quality ofrnentire power system.
