研究了多时段前瞻调度中的时间不一致性问题,指出该问题源于线性成本假设,并探讨了单次调度序列能否实现高效结果。

Abstract

Many market-based power systems have implemented a form of ‘look-ahead dispatch’ which simultaneously solves for the optimal dispatch and prices over several intervals into the future. A few papers have pointed out that the dispatch outcomes which emerge from look-ahead dispatch may not be time consistent. We emphasise that this time inconsistency is not inherent in look-ahead dispatch but is a consequence of the assumption of linear cost and utility functions, which is arguably a special case. Various augmentations to the dispatch process to resolve the time inconsistency problem have been proposed, but these augmentations suffer from the drawback that they do not allow the power system to efficiently adjust to new information. We query whether it is necessary to implement multi-interval real-time markets. We show how under certain assumptions, a sequence of one-shot dispatch processes will achieve the efficient outcome.
