Flexible AC transmission system; Static synchronous compensator (STATCOM); Optimal reactive power dispatch (ORPD); Chemical reaction optimization (CRO); Transmission loss Abstract Optimal reactive power dispatch (ORPD) problem has a significant influence on optimal operation of power systems. However, getting optimal solution of ORPD problem is a strenuous task for the researchers. The inclusio...

The paper investigates the use of dissipativity-based control for voltage-sourced inverters (VSI) utilized as reactive power and unbalance compensators, e.g., Static synchronous compensator (STATCOM). The approach relies on a frequency domain modeling of system dynamics using positive sequence and negative sequence dynamic components. Following the passivity-based procedure, a family of control...

Voltage control and fast reactive power compensation are two main application area of Static Synchronous Compensator (STATCOM), which is a shunt connected voltage source converter (VSC) based FACTs controller using power semiconductor devices (particularly IGBT, GTO etc.).However, the total Statcom circuitry has complex and coupled system dynamics which require advanced controllers to achieve w...

The objective of the paper is the application of modular multilevel cascade converter based on double star bridge cells (DSBCs) to a Static synchronous Compensator (STATCOM), for reactive-power control. The power consumed by the heavy load will create an unsymmetrical current will reducing the quality of the power in the electrical grid. Due to the unsymmetrical current the electrical power in ...
