AGC tuning of TCPS based hydrothermal system under open market scenario with particle swarm optimization

Abstract EN

This paper demonstrates the analysis of Automatic generation control (AGC) of a two-area interconnected thyristor controlled phase shifter (TCPS) based hydrothermal system in the continuous mode under open market scenario.

Further the use of particle swarm optimization in optimizing the value of integral controller has also been reported.

The effects of nonlinearities like deadband and generation rate constraint on the system have also been investigated.

Open transmission access and the evolving of more socialized companies for generation, transmission and distribution affects the formulation of AGC problem.

So the traditional AGC two-area system is modified to take into account the effect of bilateral contracts on the dynamics.

A control strategy using TCPS is proposed to provide active control of system frequency.

Gain settings of the integral controllers without and with TCPS are optimized using the particle swarm optimization following a step load disturbance in either of the areas.

The results reported in this paper demonstrate the effectiveness of the particle swarm optimizer (PSO) in the tuning of value of integral controller.

The enhancement in the dynamic response of the power system is verified through simulation results
