Easy Grid is a JS/PHP tool kit for data linear lists management. It can help you to create quickly
interfaces of table list navigation and modification with AJAX features. High performance of the
Grid is ensured by JSON data format. The Easy Grid includes sorting, filtering, pagination and mouse
right click context menu.

observable distribution Grid are investigated. A distribution
Grid is observable if the state of the Grid can be fully determined.
For the simulations, the modified 34-bus IEEE test feeder is used.
The measurements needed for the state estimation are generated
by the ladder iterative technique. Two methods for the state
estimation are analyzed: Weighted Least Squares and Extended
Kalman Filter. Both estimators try to find the most probable
state based on the available measurements. The result is that
the Kalman filter mostly needs less iterations and calculation
time. The disadvantage of the Kalman filter is that it needs some
foreknowlegde about the state.
