The invention discloses an electric vehicle charging strategy optimization method based on a QPSO algorithm, relates to an electric vehicle charging strategy optimization technology, and aims to solve the problem that centralized charging and quick charging of electric vehicles are uncertain and threaten the safe operation of a power grid. Meanwhile, by charging the electric vehicle, the problem of photovoltaic local consumption is solved. The method comprises the following steps: establishing a micro-grid model for electric vehicle charging; defining an optimization objective function of the micro-grid model; obtaining an electric vehicle charging strategy according to the defined optimization objective function; and optimizing the electric vehicle charging strategy based on the QPSO algorithm. The method has the advantages that a more reasonable charging strategy is made for the electric vehicle, the photovoltaic local consumption capacity in the micro-grid is improved, it is guaranteed that impact on the power grid is as small as possible, the QPSO algorithm is adopted for optimizing the charging strategy of the electric vehicle, and the problem that the objective function is not converged due to the fact that the optimization dimension of the PSO algorithm is high is solved.
