论文摘要
离散控制设备DCD的频繁致动,例如,加载Tap Changers会大大降低其寿命。反过来,这又增加了巨大的替代成本。这些\ textsc {dcd} s和连续的控制设备(例如分布式能源资源)同时安排这些\ textsc {dcd} {dcd} s和连续的控制设备,这对于降低运营成本至关重要。这也增加了\ textsc {dcd} s的寿命,并有助于避免使用亚最佳/不可行的解决方案。考虑到离散控制措施的高成本(DCA),在短期安排范围内(SH)中,它们可能永远不会与其他选项合理。长期以来,他们的收益较长,为DCA辩护。但是,较短的\ textsc {sh}有助于对冲不确定性促成的风险。在这里,该系统的未来被建模为一组多个周情况。操作员利用了一个长的SH,但仅应用了第一个阶段做出的决定,并等待更新的数据以做出下一个决策。这可以通过战略性地应用DCA在不可避免的同时避免不需要的时间来降低成本。拟议的基于分支和切割的解决方案方法可以准确处理DCA,同时应用一些加快启发式方法。在分支过程中,全球融合的信任区域算法解决了整数放松的问题。
The frequent actuation of discrete control devices dcds, e.g., on-load tap changers, drastically reduces their lifetime. This, in turn, imposes a huge replacement cost. Simultaneous scheduling of these \textsc{dcd}s and continuous control devices, e.g., distributed energy resources, is imperative for reducing the operating cost. This also increases the lifetime of \textsc{dcd}s and helps to avoid the sub-optimal/infeasible solutions. Considering the high cost of discrete control actions (dcas), they may never be justified against the other options in a short scheduling horizon (sh). With a longer sh, their benefits over a long period justify dcas. However, a shorter \textsc{sh} helps to hedge against the risk impelled by uncertainties. Here, the system's future is modeled as a set of multi-period scenarios. The operator exploits a long sh, but solely applies the decisions made for the first period and waits for updated data to make the next decisions. This enables cost reduction by strategically applying dcas prior to the time that they are inevitable while avoiding them when unneeded. The proposed branch-and-cut-based solution methodology accurately deals with dcas while applying some expediting heuristics. During the branching process, a globally convergent trust-region algorithm solves the integer relaxed problems.
