Technical Specialist, Grid Transition

About the role

The New York Independent System Operator (NYISO) manages the efficient flow of electricity on more than 11,000 circuit-miles of high-voltage transmission lines, dispatching power from hundreds of generating units across the state. The New York Independent System Operator (NYISO) applies cutting-edge technology to operating a reliable electricity system, managing competitive markets for wholesale electricity, and planning for the Empire State's energy future. The NYISO's Operations department invites applications for a full-time Technical Specialist, Grid Transition. The Technical Specialist, Grid Transition will provide advanced technical expertise and execution leadership for engineering studies, analytical methods, and modeling activities supporting the transition of the New York bulk power system to increasing levels of inverter‑based resources (IBRs), distributed energy resources (DERs), large loads and emerging grid technologies. The Technical Specialist will also lead and support in‑depth investigations into anomalous system conditions, disturbances, and emerging technical issues, providing rigorous technical assessments to support system operations and planning. The Technical Specialist will independently on complex technical assignments, mentors engineers as needed, and collaborates closely with the Principal, Grid Transition to ensure analytical rigor, technical consistency, and applicability of study outcomes across NYISO processes. The Technical Specialist is expected to be a deep technical contributor and integrator, owning complex study workstreams, refining analytical methods, and translating evolving technical findings into actionable recommendations for planning and operations. This individual would have a high level of technical proficiency in in topics such as frequency response, short-circuit strength, ramping issues, control interaction, and IEEE guidelines. This individual will have expertise in conducting specialized power systems analysis such as electro-magnetic transients as it pertains to various industry standards. Examples of additional studies includes Sub-synchronous torsional interaction studies (SSTI), week grid stability studies (both in RMS and EMT domain), use and development of advanced study methods and approaches to identify system resonances (such as impedance/frequency scans), among other topics. ESSENTIAL DUTIES and RESPONSIBILITIES Subject matter expert for inverter-based technologies and intermittent resources and their application in transmission planning, operations, and system analysis and modeling. Execute and support specialized analyses including weak‑grid stability assessments, reduced short‑circuit strength evaluations, sub-synchronous and super‑synchronous interaction studies, resonance identification using impedance and frequency scan techniques, and fault ride‑through and recovery evaluations. Lead dynamic simulation (PSSE) and transient simulation (EMTP, PSCAD) involving complex control systems modeling, discrete model representation of electric power system network, evaluation of transient response, addressing oscillatory issues, examination of transient phenomena (fault recovery, and transient recovery voltage estimation) affecting power system reliability Develop techniques to efficiently assess the impact of Distributed Energy Resources (DER) and Large loads on the grid dynamics and develop mitigation strategies Apply broad-based knowledge of NYISO's tariffs, system modeling and analysis techniques, markets, operations, to execute and improve system planning processes and studies. Develop detailed engineering study reports, NYISO manuals and other procedures. Proficiency in power system simulation programs mandatory from steady-state analysis to complex, rigorous dynamic and progressively more complicated transient modeling and simulation Stay up to date with the power system planning industry activities and potential future changes and drivers to adapt the NYISO's planning process, models, and system analysis techniques. Use a broad-based knowledge of NYISO's systems, markets, operations, and processes to develop and improve complex system models used in transmission security and operations engineering to plan and simulate the future electric grid ( e.g ., 1 through 10 years ahead, or longer as required). Adapt the models and methods to rapid electrical power system changes. Oversee the evaluations of the reliability of the future bulk power system by leading, reviewing or performing long and short-term reliability assessments of transmission and resource adequacy using applicable software tools such as Siemens' PSSE, PowerGem's TARA, PSCAD, ETran and similar, and applicable reliability criteria, procedures, and guidelines. Critically analyze and interpret the results and develop internal and external communication materials. Coaching team members in elevating their domain expertise for EMTP special studies that support planning and
