SBIR Phase I: Preventive, Corrective, and Emergency Control for Equipment Outages Producing Voltage Collapse and Blackout

这个小企业创新研究（SBIR）第一阶段项目将开发一种自主的方法，用于治疗电力系统中可能发生的电压崩溃和停电，当负荷流没有解决方案时。这种方法可以识别系统中超过100种不同的电压崩溃问题，而目前的方法只能检测到两三种。它可以找到1000个或更多的双设备停电，没有潮流的解决方案是未知的，由于压倒性的计算需要找到他们。对于没有负载流解的每个这样的设备断电，该方法将确定（a）解的缺乏是否是由于负载流算法收敛问题;（B）超过100个电压崩溃问题中的哪一个正在产生停电;（c）解的缺乏是否是由于不足的足够无功供应以及将使得能够找到负载流解的校正或预防控制;（d）缺乏解决方案是否是由于网络无功损耗，其需要减少负载（紧急控制）以使得能够找到负载流解决方案;（e）需要非常少的控制改变的校正和/或紧急控制，因为其取决于引发停电的子系统的结构。该方法可用于电力系统的设计、调度和在线控制。目前，平均需要15个小时的工程人力/计算时间来获得解决方案，并且在许多情况下无法找到解决方案。所提出的方法可以预期在没有人工干预的情况下，为每一个在几秒钟内无法解决的设备停机获得预防性、纠正性或紧急控制解决方案。它完成了任务，因为它学习并获得了系统结构的知识，这些知识产生了级联不稳定性，即电压崩溃和停电。该项目通过减少停电以及与电力中断相关的经济和社会成本，具有巨大的商业潜力。

This Small Business Innovation Research (SBIR) Phase I project will develop an autonomous method for curing voltage collapse and blackout in a power system that may occur when a loadflow has no solution. This method will identify over 100 different voltage collapse problems in a system when current methods may only detect two or three. It can find 1000 or more double equipment outages that have no loadflow solution that are unknown due to the overwhelming computation required to find them. For each such equipment outage that has no loadflow solution, the method will determine (a) if the lack of solution is due to loadflow algorithm convergence problems or not; (b) which of the over 100 voltage collapse problems is producing the blackout; (c) whether the lack of solution is due to insufficient sufficient reactive supply and the corrective or preventive control that would enable a loadflow solution to be found; (d) whether the lack of solution is due to network reactive losses that require reduction in load(emergency control) to enable a loadflow solution to be found; (e) the corrective and/or emergency controls that require very few control changes because it depends on the structure of the subsystem that initiates the blackout. the method would be used in design, scheduling, and in on-line control of power systems. Currently, it takes an average of 15 hours of engineering manpower/ computation time to obtain a solution and in many cases no solution can be found. The proposed method can be expected to obtain a preventive, corrective or emergency control solution for every equipment outage that has no solution in seconds and without human intervention. It accomplishes the task because it learns and acquires knowledge of the structure of the system that produces cascading instability that is voltage collapse and that produces blackout. This project has substantial commercial potential by reducing blackouts and the economic and societal costs associated with power interruption.
