Framework for evaluating the generation cost and wind power generation capacity constrained by operating reserve

The outputs of wind and photovoltaic power generations, which differ from the conventional thermal and nuclear outputs, fluctuate with the weather condition and so are difficult to forecast. Therefore, it is necessary to provide additional operating reserve corresponding to renewable energy sources. In this paper, we propose a framework for evaluating the fuel cost corresponding to a large amount of wind power generations, and evaluate the maximum installed capacity of wind power generations. The evaluation method assumes bilateral operating reserve and electricity, which affect the maximum installed capacity of wind power generation and the fuel cost of each region. The calculation results show that the cost of the additional operating reserve will increase as wind power generation spreads.
