Optimum placement of measurement devices on distribution networks using integer linear k-means clustering method

In distribution networks, PMU (Phasor Measurement Unit) is required for each node or bus, but the cost of installing PMU is quite expensive, so optimization of PMU placement is required. This study uses the Integer Linear K-means Clustering method and uses the parameters of voltage, current and impedance. This method is a combination of Linear Integration and K-Means methods used for optimizing PMU placement. The object used for research is the Bendul-Merisi distribution network which has 11 buses. The results showed that the Integer Linear K-means Clustering method can be used for PMU placement optimization. With a network of 11 buses, only 3 PMU is needed, resulting in a reduction in the number of PMU by 73%.
