Abstract

The embodiment of the invention discloses a method for optimizing the capacity configuration of an electric vehicle substation in a virtual power plant. The method includes taking the battery system capacity of the electric vehicle substation, the rated power of PCS and the planned charging and discharging power of the electric vehicle substation in each period as decision variables, the actual power of the wind farm and the actual power exchange demand in each period as stochastic variables to establish the capacity optimal allocation model of the electric vehicle substation; determining theoptimal battery system capacity and PCS rated power by the optimal objective of the capacity optimization model, which is to maximize the probability of the unsatisfied power index, the abandoned windpower index and the annualized income index. The method fo the invention comprehensively considers factors such as battery, PCS price, valley peak power price and the like, determines the capacity configuration of battery system and PCS, thereby guiding the capacity configuration of electric vehicle substation, and effectively improving the feasibility of planning results in actual operation.

Description

technical field [0001] The invention relates to the technical field of power plant parameter optimization, in particular to a capacity optimization configuration method of an electric vehicle swap station in a virtual power plant. Background technique [0002] Electric vehicle swap stations need to be equipped with a certain amount of redundant batteries. Due to the high cost of power batteries, excessive redundancy will significantly increase investment and operation and maintenance costs, resulting in a waste of resources. Insufficient redundancy will reduce the "low cost" of electric vehicle swap stations. The ability to "charge high and discharge" makes it difficult for the virtual power plant's power generation plan to match the peak and valley electricity prices, reducing the virtual power plant's electricity sales revenue, and even failing to meet the demand for power replacement in severe cases. Therefore, the capacity allocation of electric vehicle swapping stations...
