Build, maintain, and version-control the plant-level PSCAD EMT model: grid-forming BESS PCS, PV inverters, MV collection, transformers, cables, grounding, and a representative data center load (UPS, rectifier front ends, and load-step profiles). Run islanded EMT studies: black start and energization (transformer inrush, cable charging), large load steps and load rejection, fault ride-through, fault current contribution in the 1.1 to 1.5x rated range, unbalanced faults, and protection operation.
