Project Description
Many coops are seeing 1-2 distributed energy resource interconnection requests per day, which require significant engineering hours to review and approve. There is also increasing demand for hosting capacity maps, which tell consumers whether their interconnection request could be approved or not based on current system capacity.
The MOHCA project has developed scalable algorithms for estimating the voltage- and thermal-constrained hosting capacity at smart meter locations using AMI data. Calculating capacity from AMI instead of circuit models can increase accuracy, speed of execution, and reduce data management burdens. These algorithms are flexible and also allow for identifying optimal inverter settings, and evaluations of time-series hosting capacity. Faster hosting capacity analysis enables updating hosting capacity maps more frequently to ensure their accuracy with respect to recent changes on the distribution system.
Project Outcomes
The project
final report available details how the algorithms work and how they perform (90%+ agreement with slower circuit-based results with 90% less time needed to execute the analysis).
The algorithms are available to use online via a
graphical hostingCapacity tool on OMF.coop. Please see the
supporting documentation for an overview of how to use the algorithms and the resulting hosting capacity maps and results.
