ABSTRACT
This chapter presents a multiagent-based automatic generation control (AGC) scheme for isolated power systems with dispersed power sources such as photovoltaic units, wind generation units, diesel generation units, and energy capacitor systems (ECS) for the energy storage. In the proposed AGC scheme, the system frequency monitored on a diesel unit is regulated to its nominal frequency by balancing the total generation and the total power consumption in the isolated power system. The variation of power consumption at the variable load can also be absorbed through the charging/discharging operation of the ECS units. In the conventional scheme, the diesel units are utilized for the AGC system to regulate the power generation following the monitored frequency deviation on itself. The performance of the proposed AGC scheme is examined in the presence of various load disturbance scenarios. The experimental results clearly indicate the advantages of the proposed control scheme in comparison to the conventional AGC framework.
