Based on the water source heat pump technology， a novel mode on wind power accommodation is proposed. The principle of this mode is analyzed firstly， its impacts on the improvement of the wind power accommodation， the promotion of energy-saving and emission-reduction， the improvement of city heat supply and the economic enhancement of the electrical generation enterprises are studied. With the proposed mode， the residual heat of the circulating water in the heat-engine plants can be recycled to improve the quality of city heat supply， the stability of the heat supply network and the capacity of wind power accommodation in the power grid， and reduce carbon emission during the process of electric power generation. The economic， social， environmental benefits and its application prospect are verified by the research data.
