Table 2
The execution procedure of SPEA2 for BOCC.
| Input: The total power regulation command for the current control interval. | 1: Initialize the parameters of SPEA2; | 2: Initialize the parent population and archive of SPEA2; | 3: Calculate the initial dispatch solution by equations (1)–(7); | 4: Compute the objective function for each individual by equations (8)–(10); | 5: Evaluate the fitness function for each individual by equation (11); | 6: Merge the generation population and the generation archived population into one. | 7: Calculate the parameters of the new set by equations (12)–(16); | 8: Compare the number of noninferior solutions and archive size, and then perform the truncation or reproduction to fill the archive set. | 9: Generate the offspring population by applying recombination and mutation operators to the set | 10: If the termination condition of SPEA2 is satisfied, then go to the next step; otherwise, return to Step 4; | 11: Find the best compromise solution from multiple solutions in Pareto solution set by grey target decision-making theory in equation (17)–(25). | Output: The best power regulation inputs for all AGC units. |
