| Abstract | This research presents a comprehensive analysis of the dynamic performance of the impending international connection between the Philippines and Sabah, Malaysia as part of the 14 interconnection projects of the Association of Southeast Asian Nations’ power grid. Motivated by the energy security and reliability issues within the region together with the eyed economic boons, international linking have been pointed out as a viable and less expensive solution to overcome the growing energy demand. Aimed to model and evaluate the dynamic performance of the power grids given with interconnection and otherwise, this study focuses of the rotor angle stability of abovementioned power grid models. Power flow together with small signal stability and transient stability analyses are done to probe the ability of the proposed linked power system models to withstand small and large disturbances using the free and open source software Power Systems Analysis Toolbox (PSAT) in Matlab ® environment. Both static and dynamic modeling is done based on the data collected. All the components used in the models are documented in PSAT library. PSAT models for the renewable energy resources are also utilized to observe the systems’ behavior towards high penetration of renewable power sources. The new model for hydro-turbine governor is applied throughout the lumped hydropower plants as contrasted to the conventional thermal power plants. The system is tested to run in the case where the interconnection is not present to ensure that the data are reliable and that the system is suitable for further interconnection. Static power flow is indispensable in all simulations since this serves as the initialization phase of the dynamic components. Newton-Raphson method is used for the power flow. High Voltage Direct Current links are installed to conjoin existing grids. The parameters used in all components are based on the available literature reviewed. The IEEE parameters are also used in the absence of data. There are no publicly available research works done using reduced and approximate data of the system. Eigenvalues, participation factors and damping ratios of the dynamic components are the key indicators for the small signal stability. The time domain simulation for voltage, rotor speed and rotor angles results are also instrumental in the evaluating the transient stability of the system. Further, the Transmission Development Plan of the Philippines has stipulated the high involvement of solar and wind power sources in the year 2023. These data are applied in the model to investigate the model’s performance when this is realized. To understand the system’s behavior, two cases are studied, namely: (1) the load is increased in the event of increasing the area’s generation through the addition of renewable energy sources and; (2) the renewable energy power plants serve as replacement to the conventional thermal power plants, that is by reducing the capacity of the proximate thermal plants to compensate the generation increase. This paper ends with corroboration that the system is generally stable when the interconnection is realized given with appropriate parameters of the dynamic components. This is evident in the time domain simulation results for voltage, rotor angles and rotor speed. Eigenvalues also show stability when the interconnection is installed. Further, the system’s critical eigenvalues also show improvement as the renewable energy sources are augmented. |
