Abstract: The coordinated development of wind and solar power has become the focus of China's renewable energy development in the current and future. Based on the principle of system peaking regulation balance, and with combination of the statistical characteristics of wind power and solar power output characteristics, an integrated analysis method is proposed for accommodation of wind and solar power. By firstly determining the installed capacity of wind power through system power balance for the night peak load period in a typical day, and then figuring out the installed capacity of solar power through system power balance for the midday peak load hours, the proposed method effectively solves the problem of uncertainty for the conventional peak regulation balance method, which determines the combined installed capacity of the wind and solar power through peak regulation surplus. The simulation results have validated the effectiveness of the proposed method.

Key words: peak regulation balance, wind power, solar power, accommodation
