The invention discloses a wind-photovoltaic-energy storage complementary microgrid energy storage current converter comprehensive control method. Filtering is performed by using a first-order low-pass filtering method, output power of distributed power supplies is sampled firstly so that primary sampling values are obtained, and filtering is performed by using a first-order low-pass filter so that primary filtering output values are obtained; then the output power of the distributed power supplies is sampled so that secondary sampling values are obtained, filtering is performed by using the first-order low-pass filter so that secondary filtering output values are obtained, and the primary filtering output values and the secondary filtering output values are weighted so that effective filtering values are obtained; therefore, the output power of the distributed power supplies is sampled and filtered in real time in the same manner. The unbalanced power of the distributed power supplies can be suppressed so that the influence of accessing of the distributed power supplies on a power grid can be reduced, control of microgrid energy dispatching can be realized, and the microgrid operation technical indicators, stability and economic efficiency can be enhanced.
