The invention discloses a grid structure optimization strategy considering splitting definition, and the strategy comprises the steps: carrying out the linearization of all nodes of a system, and constructing a system node correlation matrix; considering an inertia factor of a generator in the system, and combining the relevancy matrix to construct an index reflecting the system splitting definition; based on a genetic algorithm, building a single-target optimization model of grid structure optimization; and taking the index of the splitting definition as a target function, and under the constraint condition of the optimization model, carrying out grid structure optimization by utilizing a genetic algorithm to obtain a grid structure with clearest splitting. According to the optimization strategy, on the basis of the relevancy matrix, the influence of generator set inertia on system grouping is considered, the compactness inside the area and the distinction degree between different areas are reflected, the la
