After flexibility market will be established in Japan in 2021, the role of demand response (DR) will not be only for securing capacity (kW) and adjustment of power consumption (kWh), but also for adjustment of the power grid (⊿kW). Services which require faster response generally have higher market prices because limited resources are able to bid. DR services might be continuously monetized with the balancing market. To consider commercialization of DR and Virtual Power Plant (VPP) in Japan in the future, it is important to watch the foreign cases where ancillary service market operations are ahead, and to investigate price level and resource type there. We clarified price trends in three markets in the UK, Germany and the US, and resource type trends. In the UK and Germany, we conducted interviews with DR operators who hold demand-side resources to understand the actual situation and future directions.

We developed the scheme of profitability analysis of a microgrid. The scheme consists of 4 processes. The first process is to calculate the optimal sizing of energy supply system in a microgrid by solving mixed integer non-linear programming by using the General Algebraic Modeling System (GAMS). The second one is to determine the distribution of system equipment by taking space in each area into account. The third one is to design electric equipment, such as transmission. The forth one is evaluation of pay-back time, reduction rate of primary energy consumption and that of carbon dioxide emission. By using this scheme we also evaluate pay-back time about construction of a microgrid in Tokyo.
