A Hierarchical Interactive Approach to Power System Restoration

这个建议是关于电力系统中失去部分或全部负荷的恢复服务。在停电或限电的情况下，系统可能会分离成独立的孤岛，需要先恢复孤岛内的负荷，再恢复孤岛间的互联。提出了一种由直接控制层、优化层和自适应层组成的分层多层恢复方法。这里的重点是最后两层，将问题表述为多阶段多目标顺序决策问题。停电后的电力系统恢复问题是一个重要的问题，但很难用严格的数学方法来表述。将采用这种方法开发一种新的公式。更好的恢复技术的任何成功都将导致更短的停电时间。

This proposal is concerned with the restoration of service in a power system that has lost some or all of its load. In a blackout or brownout situation, the system may separate into separate islands and it is necessary to first restore the load within the islands and then restore the interconnections among the islands. The restoration is proposed to be done with a hierarchical multi-layer approach consisting of a direct control layer, an optimizing layer, and an adaptive layer. The focus here is on the last two layers with the problem formulated as a multi-stage multi-objective sequential decision problem. The problem of power system restoration after a blackout is an important one but has been very difficult to formulate in a rigorous mathematical way. A new formulation is to be developed in this approach. Any success at better restoration techniques will lead to shorter periods of power outages.
