Study on Scale Optimization of Pump-storage Variable Speed Units Based on Power System Operation Simulation
摘要
Abstract
The pumped-storage power units,especially variable speed units,have great roles in guaranteeing power system operation safety,stability and efficiency.As the investment cost of pumped-storage variable speed unit is higher than fixed speed unit,it is necessary to study its scale optimization.A scale optimization model for variable speed units is built based on power system security constrained unit combination model,which can demonstrate the most economic scale of variable speed units in all new pumped-storage power units under a given power supply planning.A calculation example of a west region in China shows that the power system will has a best operation benefit when the capacity share of newly-built pumped-storage variable speed units is about 33％.关键词
