The invention discloses a multi-dimensional evaluation analysis method and system for unit cluster coordination and transaction combination optimization, and the method comprises the steps: obtaining the operation data of each generator set of a power grid, and determining the generator sets which have the same power flow direction and are not subjected to network constraint in the power grid as cluster units participating in the cluster coordination and transaction combination optimization; calculating a power generation coal consumption saving degree index of a cluster transaction combination, a standby adequacy comprehensive index of a cluster unit combination and a power transmission equipment power flow load rate balance degree index according to the operation data of the cluster unit; calculating a multi-dimensional comprehensive benefit evaluation index based on a nonlinear exponential function; and evaluating whether the multi-dimensional comprehensive benefit evaluation index meets a set requirement,
