Research on the Online Intelligent Decision-making System of Power-grid Security Based on Power Grid Crisis Management

Power grid crisis happening at home and abroad warns the urgency of power grid crisis management. It is necessary to research on online intelligent decision-making system of power-grid security based on data mining. This paper studies the status of foreign online intelligent decision-making system of power-grid security and the concrete application of foreign online intelligent decision-making system of power-grid security. Based on advanced data mining technology, by online updating safety limit-rules and automatically digging out the running rules, the safe limit values are in line with actual condition of power-grid, dispatchers can adjust the grid by running this limit and can obtain a larger cross-section delivery power-flow. In such a way, it not only can ease the power shortage situation of the system, but also improve poor power transmission ability, and produce economic benefits.
