In this paper is reflected the approach of the monitoring and control problem of the Smart Grid network, within which the energy storage is obtained from renewable resources: solar panels, wind turbines, etc. The smart grid is envisioned as a large-scale complex system that can improve the efficiency and robustness of power and energy grids. One side is forecasting API, that has been tested based on collected data from real Smart Grids mounted in Republic of Moldova. The aim is to determine if the Forecasting API can be used for such purposes and what are the best usage conditions.
