Power System Stochastic Economic Dispatch Considering Uncertain Discharge Capacity From V2G
V2G technology achieves a two-way interaction of the grid and electric vehicles (EVs),it makes plug-in hybrid electric vehicle (PHEV) be able to access grid and participate in grid scheduling.By V2G technology,PHEVs can provide FM and spinning reserve ancillary services such as economic dispatch.With the extensive use of plug-in hybrid electric vehicles (PHEVs),its important impact on charge and discharge process will be the grid safe and economic operation.Firstly,the article proves the V2G discharge capacity of a normal distribution from the theory,and based on which to establish a stochastic economic dispatch model.The results which obtain by using the IEEE 14 node system simulation show that this conclusion of the constructed model is feasible and effective,and the conclusions that the V2G node optimal active output power and minimum scheduling cost expectations are proportional to the the V2G discharge capacity expectations are also obtained.
