Abstract

With the steadily increasing penetration of wind power into the grid, wind power is likely to displace the output of some thermal units and this can result in a reduction in fuel consumption and harmful emissions. On the other hand, due to the volatility of wind power, it brings great influences to power system frequency-regulating. Then, considering of the demand of system frequency-regulating, this paper focus on studying the changes of system reserve after wind generation participating in system frequency-regulating. And on this basis, the expressions of operation value of grid integrated wind power is obtained, considering of generating revenue, generating cost, ancillary service costs, environmental benefits and other factors. Then through the simulation of an actual power system, the method is verified to be useful and the influence on the operation value of grid integrated wind power whether wind farms participate in the grid frequency-regulating or not is studied. At last, it's concluded that the operation value of grid integrated wind power can be increased when wind farms participate in the grid frequency-regulating.

考虑系统调频需求的并网风电运行价值分析

随着风力发电逐渐进入电网，风力发电很可能取代一些火力发电机组的输出，这可能导致燃料消耗和有害排放的减少。另一方面，由于风电的波动性，给电力系统的调频带来很大的影响。然后，考虑到系统调频的需求，重点研究风电参与系统调频后系统储备的变化。在此基础上，考虑发电收益、发电成本、辅助服务成本、环境效益等因素，得到并网风电运行价值的表达式。然后通过实际电力系统的仿真验证了该方法的有效性，并研究了风电场是否参与电网调频对并网风电运行值的影响。最后得出风电场参与电网调频可以提高并网风电的运行价值。
