In areas not connected to the main electricity grid, the implementation of the autonomous microgrid requires optimal management of power consumption. In the Mafate circus on Reunion Island, a microgrid is being tested for three neighbouring houses. The production system consists of photovoltaic panels and battery storage system. The objective is to minimize electricity consumption by varying the time slots of use of electrical appliances in order to achieve the autonomy of the system if the solar forecast is pessimistic, while keeping the comfort of users at a good level. To achieve this, a large mixed integer linear programming has been developed. The goal of this study is to initiate the optimal control of the microgrid system starting with the activation of each service or electrical appliance of the houses in an optimal way by minimizing the service dissatisfaction or the gap between the service end time desired by the users and the service end time calculated by the system. This approach aims to start the experiment by modeling each service of the three houses one by one in order to facilitate the integration of all the services in the large optimization model by combining the production means and the storage. The results allow to minimize the dissatisfaction of the services and thus to maximize the comfort of the users.
