摘要:
随着大规模风电并网容量的快速增加，机组的调峰容量已经满足不了不断增大的调峰需求，弃风愈加严重，风电功率送出受到了严重的制约。提高电网调峰裕度成为当前亟待研究和解决的问题。本文基于大规模风电接入电网，首先对大规模风电并网对系统调峰裕度的影响进行了分析，然后对高载能负荷的调节特性及其参与调峰的可行性进行了研究，在此基础上，研究了高载能负荷参与调节对调峰裕度的影响。最后以实例进行了仿真计算分析，验证了高载能负荷参与调节可显著增大系统调峰裕度。
In recent years, wind power generation capacity keeps a rapid growth, and the peak regulation capacity of conventional unit can’t meet the increasing needs of peak regulation, and the problem of wind power curtailment becomes increasingly serious, so the output of wind power is restricted. Raising the peak regulation margin has become an important problem to be studied and solved. Under the condition that a significant wind power integrates into the system, this paper first ana-lyzes the influence of significant wind power integration on the system’s peak regulation margin, and then discusses the high-energy load’s characteristics and its feasibility of helping peak regula-tion. Based on this, this paper studies the influence of the high-energy load’s participation on the system’s peak regulation margin. Finally, an example is illustrated and researched with simulation, and the simulation results prove that the high-energy load’s participating in regulation can increase the peak regulation margin effectively.
