“…The obtained results, Fig 4, and Fig 5, show the proposed power ($/KW), ACO technique saved 0.62% (no emission cost) and 4.45% (considering emission cost) over the Gradient method reported in [13] of total cost. In the meanwhile, comparing the ACO results in Fig.3 and Fig.5, installing RE-PV in the micro-grid saved 2.65% of the total system cost despite of the high PV investment cost taking into consideration the emission cost of conventional generation.…”

“…The ACO technique was implemented to minimize the combined economic emission dispatch problem, equation (6). The obtained results were obtained for a daily load demand and it was compared with the results obtained by the Gradient method and reported in [13]. Fig 2, and Fig 3, shows the generation dispatch of the three generators and the total operating cost without and with emissions cost.…”

“…Results show that the ACO technique saved 0.61% (no emission cost) and 4.50% (considering emission cost) over the Gradient method in total cost. Moreover, for the gradient method, the reported dispatch power are taken from [13] without taking the emission impact into consideration. Then, the emission cost is calculated based on the optimized dispatched generation without emission consideration.…”

Summary Microgrids (MGs) can operate in two modes: grid‐connected and islanded. Islanding can be scheduled or unintentional. MG should be able to maintain its stability in case of unintentional islanding. Therefore, it is necessary to provide the required spinning reserve for stable islanding. In this paper, a two‐stage scheduling strategy is proposed to determine the required reserve for stable islanding by considering uncertainties of load and renewable generations. The proposed strategy uses advantages of the load as a reserve provider to compensate the deficiency of DGs and batteries in providing the required reserve. A novel objective function is proposed to determine the optimal amount of demand which considered as reserve. The objective function minimizes the sum of reserve preparation costs, expected cost of calling load reserve, and expected cost of emergency load curtailment. Another significant feature of the proposed model is its modularity that enables the model to be integrated with any other scheduling model. The effectiveness of the proposed model is evaluated by mathematical analysis and numerical simulations.

The complication of economic load dispatch (ELD) of an electrical power system can be considered as an optimization problem with constraints to minimize the cost and emission concurrently. The optimization problems with various objectives gain significant momentum and priority with the advancements in renewable energy sources (RESs). Many techniques have been put forward to dispense this issue, but it still remains a challenging one. The exis-
