To reduce CO2 emission, dispersed generators such as solar or wind energy has been promoted. But a problem is a difficulty to predict the unstable amount of power output which is influenced by weather change. Recently, the micro-grid system with batteries has gaining attentions as this type of system can compensate the inherent deficiency of the photovoltaic systems that its output volume fluctuates. In this paper, we propose an operational model for this type of micro-grid. The model aims to minimize the volume of electricity purchased from outside given the expected volume by photovoltaic generation, which is, based on solar radiation forecast. We also have verified the effectiveness of the model by means of numerical simulations.
