There are three PERFORM power flow cases representing the transmission system in New York state were developed by the team at the University of Wisconsin – Madison. The models were created to enable the development and testing of risk measurement and risk mitigation studies. In keeping with that purpose, each facility in the model is associated with a geographic location. Two of the cases represent a peak and off-peak hour, respectively, from 2019. The third case represents a peak hour in the year 2030 after significant green power and transmission reinforcements have been added to the system. All of the models contain the same set of over 1400 substation locations, each corresponding to substations identifiable from the EIA Energy Atlas. Many, but not all, of the transmission lines can be associated with existing geographic line routes in the atlas. Generation stations are located according to the plant locations referenced in the EIA form 860 from 2019. The 2030 case is partially based on the NYISO Comprehensive Reliability Plan for 2021-2030 and Congestion Assessment and Resource Integration Study from 2020. The models represent the high voltage transmission system including facilities 115 kV and up, plus some of the 69 kV transmission. Load and generation is represented as connected at the transmission voltage. Interconnections with Ontario and Quebec Canada, ISO New England and the PJM Interconnection are represented with proxy generators located at tie buses. The network models are provided in PSSE v33 raw format, PowerWorld pwb, and MATPOWER formats. Due to difficulties representing controllable switched shunt devices in MATPOWER, the controllable switched shunt devices are represented by voltage controlling generators with zero MW capability. Load power factor is modelled as effectively corrected to unity at the point of interconnection with the transmission system. Supplemental tables associate each bus, load or generator with a geographic location and one of the existing eleven NYISO zones. For the 2030 model, renewable projects listed in the NYISO December 2021 interconnection queue are associated with existing buses so that the model can be customized for different future scenarios. A separate file contains trajectories of hourly bus level loads corresponding to each hour of 2019. The total load in each zone reflects the real time average load experienced for that hour in 2019 but the distribution to buses in each zone is purely fictitious and performed randomly weighting buses with greater transmission connectivity than those with less connectivity. Example generator economic data derived from the EPA Continuous Emissions Monitoring database, in format ready for MATPOWER, is included Similarly, existing and anticipated DC transmission projects are represented as matched generator and load pairs.
