| Popis: | In most grid-connected photovoltaic standard installations, the generated energy is consumed by the user and in case of excess or lack the grid intervene to either absorb energy or cover the need. Such strategy involves limitations as blackout while grid failure and grid pollution with inverters harmonics. This paper proposes a novel approach that considers the grid as a complementary source to avoid the grid-connected photovoltaic system problems. An algorithm is developed to manage energy flows of a PVG/Battery/Grid installation by minimizing the grid connection for load supply. In addition, a continuous supply of the load is guaranteed even while grid failure. The proposed strategy aims to increase the self-consumption, to avoid grid pollution and to keep saving the battery from an excessive charge and discharge. Obtained results confirm a continuous load supply during stable day as well as perturbed day and an improvement of the installation self-consumption. |
