Modern FACTS devices have control sections to enhance the performance of power system.

For example, in STATCOM we can add a damping loop to its structure or in SVC we can add sample controller to enhance the transient stability of power system.

For this aim, heuristic algorithms can be used to improve or optimize the performance of the control section of these FACTS devices.

The role of heuristic algorithms on FACTS devices is to provide optimum design and control strategies.

For optimum design cost..

FACTS devices are used to improve the system performance (i.e. power flows, voltages, etc).  Heuristic algorithms are optimization techniques used to solve some especific problems in order to get "optimal solutions".

In the design phase of FACTS devices, you may want to add control loops or more sophisticated controllers in order to improve the system performance.  Therefore, heuristic algorithms can help you in order to optimize their performance.

Also, when you are planning to install FACTS devices in a power system, you may want to place the devices in especific nodes in order to get the most of your system (technically and economically), therefore, heuristic algorithms can help you to do that in an optimal way.

Metaheuristcs are efficient algorithms for solving the problem of "optimal allocation of FACTS devices in power systems". If you have questions in this regard, contact me.

Dear, all,

Thank you for your cooperation.
