“…In this part, these different components will be described to solve the problem of energy management of HMG. In the present study, we are concerned only in the energy management layer (EML), described in [7], and it has the objective of resolving an optimization hassle to determine the hourly power output of each disposable RESs for the next day, by considering the power generation and consumption. EML is mainly focused on economics, considering factors like capital costs, maintenance and energy costs, lifetimes [8].…”

“…The global role is the reduce energy cost respecting all constraints and the performance of the control system. The supervision system as described in [7] contains four layers, which are: i) client layer which is the interface that facilitates the users to select the criteria suitable to their need; ii) prediction layer wish predicts RESs production and load consumption; iii) energy management layer wish to optimize the power flow; and iv) local layer wish is used to transfer the upper-level strategies guidelines to the lower level.…”

This work presents an idea about to design, simulation, and analysis of an operational control system in order to control and supervise the operations of a hybrid AC/DC microgrid (HMG) in the different operating modes (connected and islanded). The main task of this paper is concerned with the development and the implementation of a global optimization method for solving the problems of the energy crisis of HMG with an adequate control algorithm. The supervision system was developed in such a way that it coordinates when power should be generated by sources renewable energy sources (RES) such as PV array or wind turbine and when it should be produced by grid power in on-grid operation or with diesel generator (DG) in off-grid operation. This system is intended to maximize the use of the RES while limiting the use of the other emergency sources of energy (the utility grid and DG). The control simulation proves that the management system reduces the total cost of HMG thereby reducing the total cost of the RES. From the simulation results, the developed supervision system reduces the global operational hours of the HMG and the proposed algorithm respects the optimization in real-time operation under different constraints.
