 Real-time operation of multi-micro-grids using a multi-agent systemH.E. Keshta, A.A. Ali, E.M. Saied and F.M. Bendary Energy, 2019, vol. 174, issue C, 576-590 Abstract: The inaccurate prediction of solar irradiance, wind speed and demand load may significantly influence the operation of micro-grids. This condition causes unbalances between generation and load that lead to variations in DC and AC bus voltages, and may affect system stability. A multi-agent system (MAS) is proposed in this study to achieve optimal energy management for voltage regulation and to enhance the stability of a system under different weather conditions and load perturbations for two connected micro-grids. Optimum operation is achieved through two stages. The first stage is the optimum day-ahead energy from each source based on historical data. The second stage is implemented to maintain the balance between generation and load by considering economic operation during real-time operation. This stage can be realized by controlling converters related to each source in both micro-grids. Different scenarios are presented to evaluate the effectiveness of the proposed MAS. The simulation results demonstrate that the performance of the proposed energy management system is efficient.
