Abstract
Smart grid and micro grid technology have been attracting attention as realization method of low carbon society. Especially, energy management method is the most important technology because variable renewable energy such as photovoltaic systems will cause the issue of supply-demand imbalance. In this paper, we formulate supply-demand problem as mathematical programming problem and apply optimization method to making a plan of battery charge-discharge power and heat pump running. This scheduling function combined with some autonomous control power conditioner units achieves robustness of a prediction and modeling error. The effectiveness of this method has been verified in simulation and demonstration at Toyota and Kita Kyushu city.
