“…The load consumes power directly from the DC or AC bus [14]. In physics, all the powers have a positive value, also for the proper functioning of the system, the power balancing must be respected for all tools connected to the DC bus taking into account the conversion efficiency, all this is described by [15].…”

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.

“…In Figure 2, the SHM are defined as networks able of self-correcting and with dynamic optimization capabilities based on real-time measureements to minimize energy losses while increasing reliability and its performances. They are also able to react to unforeseen situations thus facilitating the integration of renewable energy sources while increasing the quality of energy (Qachchachi et al 2016). The SHM have many capabilities that conventional microgrids do not have:…”

“…This way of control upgrade conditions for the proper functioning of the overall multisource system, such as the time required to turn mode on the diesel generator according to parameters such as the current state of charge of the batteries and the conditions of use of the loads during peak-hours. For this, the hybrid control system is based on 4 modes of use (Qachchachi et al 2016;Kumar et al 2013).…”

The fluctuation of production of renewable energy resources (RESs) is a big problem for its installation and integration in isolated residential buildings. A hybrid AC/DC microgrid facilitates the good operation of RESs with a storage system in standalone mode and the possibilities of smart energy management. In this paper optimization research of the hybrid ac/dc microgrid in isolated mode of operation is presented. The power system is supplied by various Renewable Energy Resources (RESs), Photovoltaic arrays (PVA), a Wind Turbine Generator (WTG), Diesel Generator (DG) and supported by Batteries Storage System (BSS) for short term storage. The main objective of this study is to optimize power flow within a hybrid ac/dc microgrid with regards to reliability in islanded mode. First a mathematical model optimized by mixed integer linear programming and solved by CPLEX solver with JAVA language is developed for an islanded RES system and then, based on the developed model, the power system control is simulated for different cases of off-grid mode. Simulation results have shown that the management strategy can maintain power balancing while performing optimized control and give a controllable loads and batteries charging/discharging powers, even with unpredictability of RESs powers outputs and arbitrary energy tariffs. Finally, the proposed algorithm respects the optimization in real-time operation under various constraints.%.©2020. CBIORE-IJRED. All rights reserved
