Abstract
The 275 kV Sumatra interconnection system is the second largest interconnection system in Indonesia after the 500 kV Java-Bali system. The projected load growth in the Sumatra system will reach 7.1% in 2022 along with the addition of generating capacity upto 2030 of 9.3 GigaWatt of which 5.2 GigaWatt or 53.7% are EBT generators. A smart grid system is needed to guarantee the continuity of the electric power system. Phasor Measurement Unit (PMU) is able to measure phasor voltage on the bus as well as the current flow along the lines coming to the bus in real-time. The design of PMU placement aims to find the minimum number and optimal location of PMU so that the system can be observed as a whole. In this paper, the writer will discuss how to optimally place the PMU using the Binary Particle Swarm Optimization (BPSO) optimization method, deep first, and simulated annealing. In addition, calculations of the System Observability Redundancy Index (SORI) and Optimal Redundancy Criterion (ORC) are also written to provide an assessment of the observability of PMU placement. The results obtained are expected to help provide solutions for investment efficiency in implementing smart grid systems in Sumatra.
