Abstract

Integration of more renewable energy sources (RES) undoubtedly bring more impact into power system. The distributed generation of RES in grid-connected knowingly will interfere frequency system’s stability due to decoupling to at point of common coupling. Inertia plays main role for bringing up frequency regulation at very early stage of frequency responses. Thus, to include RES such as solar photovoltaic (PV) and wind turbine (WT) could be a good idea but ideally PV has no inertia while WT only partially inertia. Therefore, the objective of this paper is to do an assessment on frequency stability specifically on inertial response with regard to unit commitment e.g. synchronous generator and RES participation. However, to know certainly the inertia constant (H) for each generator with respect to its rating ultimately difficult as it can varies depending to several factors i.e. unit type and manufacturer. Hence, an equation is proposed and yielded to facilitate for H determination of synchronous generator. The proposed equation is tested with other IEEE systems for its accuracyness. The estimated values are then simulated in various scenarios and cases i.e. increment of inertia, splitting of unit commitment and RES participation toward inertial response. MATLAB Simulink software is used to simulate and analyze the end results. Finally, the famous Kundur’s 4 Machine Two-Area Test system is used to verify the effectiveness for entire findings.
