Full-scale introduction of renewables to power systems has become an urgent policy issue of Japan due to the changes in situations after the Great East Japan Earthquake. In order to meet the requirement, it is essential to develop a smart energy management system to achieve real-time supply-demand balance even in the presence of variable energy sources while ensuring robustness against disasters. In this talk, we first outline the social/academic situation after the earthquake and, in particular, introduce a research project which is about to be launched under the initiative of researchers in the field of systems and control. We next move on to our technical work on optimal network management for distributed microgrids, which are expected as a solution to achieving both of stable supply-demand balance and robustness. Here, we focus on reduction of temporal/spatial variability of photovoltaic generation via distributed decision-making of each energy source. Then, we present an algorithm to reach total optimization based on game theoretic cooperative control techniques, and show that the information processing is almost distributed with help from a solar radiation forecasting system. Finally, we demonstrate its effectiveness through simulation by using real data from a forecasting system and a weather satellite.
