A method for operation of at least one generator system, the method comprising: a) accessing a plurality of layouts (S103) for the at least one generator system; b) calculating at least one operational quantity (S105) for each of the plurality of layouts; c) performing a comparison (S107) of the at least one operational quantity for each of the plurality of layouts; d) selecting a preferred layout (S109) from the plurality of layouts based on the comparison; and e) determining a generator system command (S111) to implement the preferred layout, wherein the generator system command controls at least one switching device (52U1, 52G1), characterized in the following method steps: f) accessing a priority setting (S101) for the at least one generator system; and g) performing the calculating step b) and the comparison step c) based on the priority setting, h) wherein the priority setting for the at least one generator system ranks input requirements, maintenance requirements, or environment requirements as a top priority in calculating the at least one operational quantity for each of the plurality of layouts; i) wherein the priority setting for the at least one generator system ranks input requirements, maintenance requirements, or environment requirements as a second priority, after the top priority, in calculating the at least one operational quantity for each of the plurality of layouts; and j) wherein the priority setting includes a coefficient for each of the input requirements, the maintenance requirements and environment requirements, and wherein the coefficients are combined to calculate an aggregate value. a) accessing a plurality of layouts (S103) for the at least one generator system; b) calculating at least one operational quantity (S105) for each of the plurality of layouts; c) performing a comparison (S107) of the at least one operational quantity for each of the plurality of layouts; d) selecting a preferred layout (S109) from the plurality of layouts based on the comparison; and e) determining a generator system command (S111) to implement the preferred layout, wherein the generator system command controls at least one switching device (52U1, 52G1), characterized in the following method steps: f) accessing a priority setting (S101) for the at least one generator system; and g) performing the calculating step b) and the comparison step c) based on the priority setting, h) wherein the priority setting for the at least one generator system ranks input requirements, maintenance requirements, or environment requirements as a top priority in calculating the at least one operational quantity for each of the plurality of layouts; i) wherein the priority setting for the at least one generator system ranks input requirements, maintenance requirements, or environment requirements as a second priority, after the top priority, in calculating the at least one operational quantity for each of the plurality of layouts; and j) wherein the priority setting includes a coefficient for each of the input requirements, the maintenance requirements and environment requirements, and wherein the coefficients are combined to calculate an aggregate value. requirements, the maintenance requirements and environment requirements, and wherein the coefficients are combined to calculate an aggregate value. <EOS>
