面向智慧工业园区的双层优化调度模型

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.%Based on the intelligent management and advanced communication network of smart industry district, it is used as an important tool for the user side's participating in a bilevel optimal dispatch of which a mathematical model is constructed.Besides, the ability that the internal loads could participate in the interaction between power and loads is estimated.In the model, the minimization of dispatch operation cost is set as the goal where the grid compensates the power shortage of smart industry district or adopts its extra power to ensure real time power balance of the whole system.The smart industry district makes optimal dispatch plan for internal controllable loads to make them participate into the system operation for the purpose of its optimal profits.Finally, the feasibility of the constructed model is proved and the comparison between bilevel optimal dispatch and single optimal dispatch is made to highlight the characteristic of bilevel optimal dispatch.The economic operation of system with smart industry districts is achieved.
