【摘要】：将智慧工业园区作为用户侧参与电网优化调度的重要平台,分析了智慧工业园区内部负荷参与源荷互动运行的能力,针对智慧工业园区参与系统运行建立双层优化调度模型。其中,电网层以调度运行费用最小为目标,对智慧工业园区功率缺额或富余出力进行补偿或消纳,保证系统实时功率平衡;智慧工业园区层在保证自身收益的情况下,对园区内部可控负荷进行优化调度,实现负荷对系统运行的主动参与。模型中采用机会约束对清洁能源不确定性进行处理。最后,在算例中验证了所建模型的可行性,比较了双层调度模式与单层调度模式的优化差异,实现含智慧工业园区电力系统的经济运行。
[Abstract]:The intelligent industrial park is regarded as the important platform for the user side to participate in the optimal dispatching of the power grid, and the ability of the intelligent industrial park to participate in the interactive operation of the source and load is analyzed. A bilevel optimal dispatching model is established for the intelligent industrial park to participate in the system operation, in which the power deficit or surplus output of the intelligent industrial park is compensated or eliminated by the grid layer aiming at the minimum dispatching cost. Ensure the real-time power balance of the system; In the case of ensuring its own income, the intelligent industrial park layer optimizes and dispatches the controllable load within the park. Realize the active participation of load to the operation of the system. In the model, the opportunity constraint is used to deal with the uncertainty of clean energy. Finally, the feasibility of the model is verified by an example. This paper compares the optimization difference between double-layer dispatching mode and single-layer dispatching mode, and realizes the economic operation of power system in industrial park with wisdom.
