Abstract

Renewable Energy System Integration is a complex nonlinear power system that exhibits severe problems with power system frequency and tie-line power deviations owing to a lack of damping factor under dynamically changing loads. However, keeping the frequency and tie line changes within acceptable limits is still a challenge. A contingency issue of electricity scarcity under critical load conditions makes the adjustment between power generation and demand complex. This equation is important to the effective management of all power systems and provides additional controllers when the integration of renewables into the conventional power system is taken into consideration. In this paper, a PID controller with particle swarm optimization (PSO) is used to control load frequency in micro-grid power system. A time-domain based objective function is designed and performed by the pso algorithm to robustly tune the variables of controllers. The proposed PSO-based control is tested under various operation condition and contract variations on a three-area micro- grid environment. The proposed PSO-PID controller's performance is compared to that of an ANFIS and conventional-PID controller using these performance indicators to emphasize its robust performance over a wide variety of load variations.
