Power System Planning Studies: steady-state real and reactive power flow including outage contingencies, generation interconnect feasibility, P-V and Q-V analysis for voltage stability margins, dynamic stability performance, automation of large batch simulations, working with models from NERC regional entities (WECC, MRO, SERC etc.), NERC compliance. Design Studies: substation grounding, corona, electric and magnetic fields, insulation coordination (lightning, switching surge, and contamination performance), transient (time domain) simulation, power quality (harmonics, voltage flicker, over/under voltage, etc.), motor starting, AC interference (transmission line interaction with railroads and pipelines).
