Systems and methods for simulating and controlling a power system in real time, using a controller, are provided. The controller includes a simulation layer to simulate an operation of the power system, a disturbance generation layer to provide data to the simulation layer to disturb the simulated operation of the power system, an application layer to display the simulated operation of the power system and generate a control signal to control, based on the simulated operation of the power system, at least one element of the power system, and a distributed data streaming server (DS) to allow interoperability among the simulation layer, the disturbance layer, and the application layer.

An adaptive controller for a static compensator (STATCOM) to enhance voltage stability comprises an outer voltage regulator loop and an inner current regulator loop. Each of the outer loop and the inner loop comprises a proportional integral controller. The outer loop adjusts proportional and integral control gains of voltage regulator. The inner loop adjusts proportional arid integral parts of current regulator gains. The automatic adjustment of these regulator gains is adaptively determined such that the voltage at the controlled bus follows a desired voltage, reference curve over time returning to a desired steady-state condition under various disturbances such as changes in load and/or transmission network. Thus, the adaptive controller can achieve a plug-and-play feature for a STATCOM without human intervention.
