【摘要】：省级电网进行发电调度优化时,其母线负荷中蕴藏的地区电网可调资源没有充分发挥其作用,从全局利益出发协同省地两级调度资源实现联合优化,可提高资源利用效率。该文提出了基于母线负荷预测改进的省地协同发电计划优化方法,根据母线负荷源荷属性进行分类,将地区有源网的电源成分和负荷成分分开考虑,改进母线负荷的预测方法;分析了地区电网节点电源和负荷在省调母线上的汇聚原理并提出母线功率转移矩阵,建立了母线可调度能力的求解模型,提出了母线价格功率关系函数的生成方法;将母线负荷作为省地协同发电优化调度的媒介,构建了省地协同优化调度模型。算例结果表明省地协同方法可实现全省范围内电源的协调互补,提高电网安全经济运行水平。
[Abstract]:When the provincial power grid is optimized for generation dispatching, the adjustable resources of the regional power grid contained in the bus load do not play its full role, and the coordination of the two levels of dispatching resources to realize the joint optimization is based on the overall interests. In this paper, an improved optimization method based on bus load forecasting is proposed to optimize the power generation plan, which can be classified according to the source load attribute of the bus load. In order to improve the forecasting method of bus load, the power component and load component of active power network are considered separately. The convergent principle of node power supply and load on the provincial bus is analyzed, and the power transfer matrix of the bus is proposed, and the solution model of the dispatching ability of the bus is established. The generating method of power relation function of bus price is presented. The busbar load is used as the medium of the coordinated power generation scheduling in the province and the cooperative scheduling model is constructed. The results show that the coordination and complementation of the power supply in the province can be realized by the coordination of the power supply in the province. Improve the safety and economic operation level of power grid.
