Description
Summary:This paper presents a simulation-based approach to study the effect of wind energy variation on the frequency regulation of a power system. In North America, the quality of frequency regulation is defined in terms of two indices known as Control Performance indices (CPS1 and CPS2). The power system is modelled as a control system with equivalent representation of turbine-governor dynamics. The system inertia is modelled as a single equivalent inertia. The power system external to the system under consideration is modelled as a single equivalent. The model is then used to study the sensitivity of CPS indices to wind variation and the settings of the Automatic Generation Controller parameters. The model also gives the amount of regulation reserves utilized in each simulated scenario.
