Spinning reserve plays an important role in maintaining stability of power system operation. Due to intermittent and randomness of wind power and photovoltaic, the rapid development of new energy sources has brought great challenges to the safe operation of the grid. With large-scale grid connection of new energy sources, the demand for spinning reserve is also growing rapidly. The shortage of demand for spinning reserve is particularly evident. In some areas with small installed capacity but high penetration of new energy. In this paper, the spinning reserve optimization under grid interconnection is studied, the subsystem types of power system are divided, optimization model of reserve capacity is constructed, process of sharing spinning reserve is quantified. Specifically, this paper uses data of four different provinces in central China to test the optimization model. Results show that this model is available and practicable.
