摘要
随着特高压互联电网的建设发展,电能交易和资源优化范围增大,现有联络线计划编制方法已难以适应;此外,大规模风电集中上网、远距离输送,对发输电计划协调也提出了新的要求。针对上述问题,文中将网络流应用于跨地区电能交易与分区开机容量的优化,提出了以系统当前开机方式为基础,以次日跨地区电能交易电量、地区间联络线输电能力等条件为约束,以分区开机容量最小为目标的发输电计划协调优化方法,建立了跨地区电能交易电量、分区开机容量的网络流模型。通过某实际系统算例说明了模型的有效性。
With the development of the ultra-high voltage （UHV） interconnected grid, increase in the volume of energy trading and optimization range of resources is beyond the power of existing tie-line power flow planning to adapt to. Besides, concentrated interconnection and long-distance transmission of large-scale wind power is making new demands on the coordination of generation and transmission scheduling. To remedy such a situation, the network flow theory is used to optimize the energy trading between regions and the regional unit-on capacity. On the basis of the present start-up modes, a coordination and optimization method for generation and transmission scheduling of power system is proposed and, with the next day＇ s energy trading power and tie-line transmission capacity between regions as constraints, and the regional unit-on capacity minimum as the objective, the corresponding network flow model is developed.
