Distributed State Estimation & System Identification 
 Look‐ahead Simulation
• Process of using a set of over determined, noisy 
measurements to estimate the system state
- V and θ are the state variables in our problem
- We use measurements that are functions of V and θ to form 
our estimate


• One of the first milestones in moving towards a Smart 
Grid is demonstrating that distributed state estimation 
is workable
