A Framework for Placement Assessment of Synchrophasor Measurement in Practical Power Grid: A Case Study from Borneo

Abstract

Security control of electricity networks has always been a key issue in the power industry development. An important approach towards full observability of power system is by means of using the phasor measurement unit (PMU). The consideration when applying PMU in power grid is the proper selection of its location. Therefore, an optimal location has to be identified in order to minimize the number of installed units, as it is not economically viable to place PMU at each bus. Firstly, this paper reviews the methods used for PMU placement. Further, the paper proposes a framework to evaluate the optimal locations of PMUs in a practical power grid consisting of 36 buses. The power grid has been modeled by taking into account the change in system configuration. Different optimal PMU placement (OPP) methods have been utilized to determine the best location with the lowest number of installed PMUs. The implemented framework for solving a practical problem using a classical approach has proven to be ideal in terms of ensuring the complete observability of the power system under single and multiple transmission line outages.
