Dynamic security enhancement strategies for power systems

我们没有意识到，但我们家的电源插座实际上是有史以来最大和最复杂的物体之一的门户！输电系统是20世纪世纪最伟大的工程成就之一。它是一个广泛的互联网络系统，其中高压电力线将电力从发电机输送到客户。我们的生活水平取决于可靠、低成本和高质量的能源供应。 然而，不可预见的事件发生，可能会干扰电能的可靠供应。还记得2003年8月的大停电吗！这给人民造成了极大的困难，给经济造成了巨大损失。一开始是一条高压输电线垂到树上。一条输电线路的断开导致其他线路携带更多的电力，这导致了“多米诺骨牌”效应，导致连锁停电和停电。 这种潜在的危险总是存在的，工程师们正在寻找使电网对这些可能的干扰更加“鲁棒”的方法。解决这个问题的方法通常被称为“安全增强”。本研究的主要目标是开发有助于提高电网整体安全性的工具。建议使用基于高级数学方法（如优化）的方法和基于“人工智能”的方法。这些工具本身或通过电力系统操作员在适当的时间执行控制动作。因此，不可预见的事件对电力系统的影响将最小化，我们可以继续享受可靠的电能供应的好处。考虑到加拿大在北美能源市场上的作用，这项研究具有重要意义。加拿大在技术领域的领导地位和进步在很大程度上取决于可靠和安全的基础设施，这些基础设施可以继续提供高质量的电能。本研究的目的是为实现这些目标做出有价值的贡献。

We don't realize it, but the electrical outlet at our homes is actually a gateway to one of the largest and most complex objects ever built ! The electricity transmission system is one of the greatest engineering achievements of the 20th century. It is an extensive system of interconnected networks in which high voltage power lines transport electricity from generators to customers. Our standard of  living depends on reliable, low-cost and high-quality availability of energy.  However, unforeseen events occur  that can disturb the reliable supply of electrical energy. Remember the blackout of August 2003 ! This caused significant hardship to the people and a great loss to the economy. It started with a high voltage transmission line sagging on to a tree. Disconnection of one transmission line caused other lines to carry more power and this resulted in a 'domino' effect resulting in cascading outages and blackout.  This potential danger is always present and Engineers are looking for ways to make the electrical grid more 'robust' to these possible disturbances. The approach to tackle this problem is referred to in general as 'Security Enhancement'.The main goal of this research is to develop tools that will help to enhance the overall security of the power grid. It is proposed to use methods based on advanced mathematical approach (such as optimization) and methods based on 'Artificial Intelligence'. These tools  by themselves or through the power system operator implement control actions at the appropriate time. As a result, the impact of unforeseen events on the power system will be minimized and we can continue to enjoy the benefits of a reliable supply of electrical energy.This research is significant considering the role Canada can play in the North American energy market. The leadership and progress of Canada in the technological world depends to a large extent on a reliable and secure infrastructure that can continue to supply high quality electrical energy. The proposed research is to make a valuable contribition to achieve these goals.
