Abstract

In power systems, the automatic generation control (AGC) system is responsible for maintaining the nominal system frequency and the scheduled real power interchange between balancing areas. This paper proposes a framework to evaluate the effects of uncertainty arising from renewable-based electricity generation and noise in communication channels on the AGC system performance. To this end, we introduce a unified stochastic differential equation (SDE) model that includes power system dynamics and the AGC system (including the communication network on which its operation relies). We propagate the uncertainty from renewable-based resources and communication channel noise through the SDE model and investigate the resulting effect on AGC system performance. The proposed ideas are illustrated through a 4-bus test system.
