【 摘 要 】

As the use of clean energy such as wind power and nuclear power has been increasing, the base load operation of nuclear power units usually means huge pressure for local power systems in regulating peak demand. In order to use more regulation resources, a multi-area joint optimization model involving peak regulating of nuclear power is proposed. Match performance of peak load regulating of wind power and nuclear power is also examined according to their output characteristics. Furthermore, aiming to make nuclear power constraint linearize, a method is introduced herein to subdivide the depth of peak load regulating of nuclear power. On the other hand, considering the power constraints of AC/DC transmission channel, wind curtailment cost and the operating cost of peak load regulating of nuclear power, a joint scheduling model with complementary energy sources in multi-area is established, which can effectively reduce the adverse impact of negative peak regulating of wind power and enhance consumption of clean energy. Finally, China’s inter-regional interconnected power system is introduced to validate the effectiveness of the proposed model.
