Comparative analysis of traditional and metaheuristic based OPF methods.
| S. number | Properties | Traditional technique | Metaheuristic techniques |
| (1) | Model formulation | Model is used to simulate a system when the system is not extremely complicated. | Metaheuristic techniques try to imitate, in a very simplistic way, the human cognition capability. | (2) | Prerequisites | Use the principles (e.g., physical laws) to derive the relationships of the system. | Dependent on data to determine the structure and parameters. | (3) | Nonlinearity integration | Possible if prior knowledge of the nature of the nonlinearity exists. | The prior information of the nature of the nonlinearity is not required. | (4) | Hypothesis | Simplifying the problem or incorporating assumptions to make model more understandable. | No need to simplify the model and/or add assumptions. | (5) | Precision & accuracy | Provide highest level of accuracy. | Provide greater precision and accuracy due to less chances of error. | (6) | Efficiency | Needs more time to solve the complex problem. | Utilized to carry out repetitive and time-consuming tasks, efficiently. | (7) | Renewable energy integration | Requires complex mathematical modelling. | With metaheuristic model renewable energy, source incorporation is easy. |
