Dynamic load modeling and parameter estimation of 132/275kv using pmu-based wide area measurement system

Abstract

Dynamic load modeling for Kuching power system is presented in this paper by practicing on real data and load models of Sarawak grid system. Load modeling is vital in the power industry since power system reliability and stability can be discovered based on the time domain simulations results. Dynamic load modeling was achieved in this paper by using MATLAB using load response and the system stability being assessed. Some parameter estimations of the load composition at the selected bus also included in this paper. The results of the simulations on load models being compared with the recorded system data in Phasor Measurement Unit (PMU) of Wide Area Measurement System (WAMs) by applying an event of bus tripping time interval. Values of estimated parameters on load composition are then being converged by using Least Square Error Method and compared with the actual recorded data until optimized load models were achieved.
