The invention discloses a virtual power plant optimization scheduling method containing storage batteries based on a unified electricity market, and belongs to the field of energy optimization research of a power distribution network. In the prior art, electric energy transaction employs a separated transaction mode of a day-ahead market and a real-time market, the transaction model breaks the previous connection between the day-ahead market and the real-time market, and the optimal electric energy transaction scheme cannot be obtained. According to the optimization scheduling method, a virtual power plant optimization scheduling model based on the unified market is built, the storage batteries can be charged in time after deep discharge, and the operation loss of the storage batteries is reduced; besides, electric energy transaction is optimized in the unified electricity market, and the benefit of the virtual power plant is increased.
