电解铜负荷参与需求侧响应功率控制方法

Power Control Method for Electrolytic Copper Load Participating in Demand Side Response

摘要:

随着高比例新能源电力系统的建设，电网调节灵活性面临着新的挑战。除电源侧外、电网测，需求侧中高耗能工业负荷也具备提升电网调节灵活性的巨大潜力。然而，目前高耗能工业负荷缺乏挖掘自身提升电网调节灵活性的手段，其参与电网需求侧响应程度并不理想。因此，以典型高耗能工业负荷电解铜负荷为例，研究其工艺流程并建立工艺流程模型，分析工艺流程中具备功率调控可行性生产设备，基于其功率特性及工艺流程耦合关联建立功率控制模型。最后，以电解铜负荷参与电网需求侧响应为例，通过与仅投切负荷控制手段相对比，验证了所提电解铜工业负荷参与需求侧响应功率控制方法的有效性，为高耗能工业负荷参与电网需求侧响应提供了一种有效的功率控制方法。

Abstract:

With the construction of a high proportion of renewable energy power systems, the flexibility of power grid regulation is facing new challenges. In addition to power supply side and power grid side, high-energy-consuming industrial loads on demand side have great potential to improve the flexibility of power grid regulation. However, currently, high-energy-consuming industrial loads lack the means to explore and improve the flexibility of power grid regulation, so the degree of its participation in demand side response of power grid is not ideal. Taking electrolytic copper load which is a typical high-energy-consuming industrial load for example, its process flow is studied and a process flow model is established. The production equipment with power regulation feasibility in process flow is analyzed, and a power control model is established based on its power characteristics and process coupling correlation. Finally, taking the participation of electrolytic copper load in demand side response of power grid for example, the effectiveness of the proposed power control method for electrolytic copper industrial load participating in demand side response is verified by comparing it with only switching load control methods, which provides an effective power control method for high-energy-consuming industrial load participating in demand side response of power grid.
