The paradigm of remote generation (G) supplying purely demand (D) is changing. There is a change in the structure of the grid, thus forming microgrids having local photovoltaic generation (PV ) and energy storage (ES).

Not only the consumers have become prosumers, but the meshed topology makes the task of supplying energy more resilient due to redundant paths.
A power-flow service is developed to provide the prosumers information on complex node voltages, powers, current injections, complex branch currents, branch losses, etc.

This helps to check whether network is operating within the steady-state limits all the while battery charging, battery discharging, load increase, load decrease, and varying photovoltaic generation events take place. It allow to check:
- Is any voltage limit getting violated at any node?
- Is any of the branch overloaded?
- Are the line-losses going beyond preset limits?
- etc.
Demonstration of Geographical Information System integrated near real-time power-flow for an electrical network at Jurong Island, Singapore. Red nodes are generations, and the green node is the lumped load.
Red branches represent the branch is over-loaded. G1 is the main land to which power is supplied.
The power-flow solution is obtained using holomorphic embedding. This helps to perform reliable power-flow in real-time.
