Impact of PMU in Dynamic State Estimation of Power Systems
Energy Management Systems (EMS) plays the all important role of monitoring and control of the power systems and state estimation forms its backbone. In these days of increased operation of power system near to its limits and the tendency to utilize the grid to its full potential, monitoring and control with high level of accuracy becomes a boon. Dynamic State Estimation (DSE) techniques with their unique ability to predict the state vector one time stamp ahead have the potential to foresee potential contingencies and security risks. Any improvement in its ability to predict or estimate would definitely go a long way in reducing the security risks in the modern day power system.
