Power Grid Crises Management and Research on Load-Model of Power Grid

Power grid crises, which have taken place at home and abroad, alert the importance of power grid crises management. This paper studies different load-model, and then adopts concrete load- model to analyze stability of Jiangsu power grid. On the base of calculated results, the paper submits the constructive suggestion on Jiangsu power grid. In order to avoid power grid crises for inadequate research on load-character and load-model, it is important theoretically and practically to utilize load-model to analyze the voltage-stability of power system.
