This paper addresses the estimation of hosting capacity in light of the rising distributed energy resources (DERs), focusing on the application of the high-precision phasor measurement unit (PMU) in distribution systems. The urgent imperatives of rapid climate change and carbon neutrality goals have accelerated the proliferation of DERs. Consequently, the expansion of DERs is outpacing the enhancement and new installation of distribution systems, highlighting the need to precisely assess their hosting capacity. This study examines the applicability of PMU in accurately estimating hosting capacity, applying an optimization-based method. Utilizing this methodology in the IEEE 33-bus distribution system, the results demonstrate that the implementation of PMU in place of conventional remote terminal units (RTU) enhances the integration capacity of DERs. Further investigations delve into how measurement uncertainty of PMU impacts the acceptability of DERs, offering valuable insights into the limitations and potential of PMU deployment in modern distribution systems.
