【摘要】：机组检修计划和机组运行组合都是电力系统电源运行结构优化的重要组成部分。风电等新能源的大规模接入和智能电网调度的推进对电力系统电源运行结构优化提出了新的要求。为了进一步提高电网运行的安全性,提高电网消纳新能源的能力,提升电网调度的精确化、智能化水平,文中提出一种内嵌N-1安全校核的月度电源运行结构优化的新模式。该模式在更长的时间尺度、更广的空间维度充分挖掘机组检修与机组组合的协同优化空间,内嵌考虑N-1安全校核,有效提高了机组检修计划与发电计划的安全性与经济性。IEEE 30节点系统和某省级电网的算例分析揭示了实现机组检修计划与运行组合协同优化的效益。
[Abstract]:Maintenance plan and unit operation are important parts of power system operation structure optimization. The large-scale connection of new energy sources such as wind power and the advance of smart grid dispatching put forward new requirements for the optimization of power supply operation structure in power system. In order to further improve the security of power network operation, improve the ability of power grid to absorb new energy, improve the accuracy and intelligence level of power grid dispatching, a new mode of optimization of monthly power supply operation structure based on N-1 safety check is proposed in this paper. In the longer time scale and the wider spatial dimension, the model fully excavates the cooperative optimization space between unit overhaul and unit combination, and takes into account the N-1 safety check. The security and economy of unit maintenance plan and generation plan are improved effectively. An example of IEEE 30-bus system and a provincial power network shows the benefit of cooperative optimization of unit maintenance plan and operation combination.
