This paper proposes a game-theoretic framework for analyzing the decentralized and centralized control of smart grids based on the availability of information. For the demand response, demand-side actors in smart grids need to obtain various types of information via communication, e.g., a house with a photovoltaic (PV) power system acts efficiently based on(More)
Differential games are multi-agent versions of optimal control problems, which have been used for modeling control systems of smart grids. Thus, a differential-game theoretic approach is a promising mathematical framework enabling to discuss a demand-side energy management system where there are multiple decision-making entities. This paper first indicates(More)
This paper proposes an RGBD cameras-based wireless environment prediction and presents an implementation of a proactive traffic control system using the prediction results. In millimeter-wave and terahertz communications, frame loss rate increases and throughput is decreased tremendously when pedestrians block line-of-sight paths. Such serious human(More)
Differential games are considered an extension of optimal control problems, which are used to formulate centralized control problems in smart grids. Optimal control theory is used to study systems consisting of one agent with one objective, whereas differential games are used to formulate systems consisting of multiple agents with multiple objectives.(More)
