Abstract

AbstractReliability and quality of power system requires the balance between power generation and load demand. Nowadays, frequency deviations have become an important challenge to resolve, due to the integration of several energy sources and deregulation. This paper addresses automatic generation control (AGC) incorporating the contribution of demand response (DR) and captive generation (CG) i.e., any distributive generation source, which indicate that apart from supplementary control, 2 more control actions are also available to provide optimal operation. Indeed, DR will become a significant entity of electrical grid network in future. The ongoing research suggests significant impacts of DR in power system domain of load frequency control (LFC) problem. Power system optimization through appropriate power sharing between DR (with communication delay), CG and supplementary control has been implemented in this paper. A PID controller tuned by Big bang big crunch (BBBC) has been used as a secondary controller. The entire study has been carried out on interconnected power systems having one and two areas respectively..KeywordsAGCDRCGPower systemDeregulation
