A total of This paper concerns with evaluation of the performance of 300MW generator units are proposed on a temporary basis to aid the main electric power grid of Oman with DGs at six in meeting the peak demand in summer 2011. locations. These DGs are required to aid in meeting peak A digital model is developed to simulate the system including central power plants, transmission system, loads and the demand in summer 2011. Benefits of installing new DGs are proposed Distributed Generation (DG). The model includes evaluated. These include improvement in voltage profile, representation of governor and excitation systems.
