Small signal stability and transient stability analysis on the Philippine-sabah power interconnection

In the advent of multinational cooperation within the Southeast Asian region, massive connectivity for both goods and services has been envisioned. Energy systems are ought to be collaborated to jointly develop a borderless electricity industry and one of which is the Philippines-Sabah interconnection to be inaugurated in 2020. This paper presents an analysis on the small signal stability and transient stability analysis of the interconnected Philippine-Sabah Power Grid. To achieve these objectives, eigenvalue analysis and time domain simulations were employed to probe the ability of the power grids to withstand large and small disturbances and maintain stable when connected. The free software, Power Systems Analysis Toolbox (PSAT), is used to develop the model using MATLAB® in Simulink® environment. There have been no publicly available studies regarding the new link. This paper ends with the validation of the dynamic stability of the new interconnection under various disturbances.
