The invention discloses a method for robustly and optimally operating micro-grids on the basis of orthogonal arrays. The method includes steps of extracting static data of micro grid architectures, power types, operation costs of the power types, energy storage system unit operation cots, interaction costs, time-of-use electricity prices and the like; building micro-grid uncertainty set models; screening test scenarios; building micro-grid robust and optimal operation models on the basis of the orthogonal arrays and designing solution strategies on the basis of the test scenarios so as to obtain ultimate micro-grid robust and optimal operation schemes. The method has the advantages that the grid-connection micro-grids with consideration of output of renewable energy distributed power sources and load demand uncertainty can be optimally operated by the aid of the method, and dispatching reference can be provided for operation personnel of the micro-grids. |
