MOD-026 & MOD-027
MOD-026-1 verifies that the generator excitation control system or plant volt/var control function model (including the power system stabilizer model and the impedance compensator model) and the model parameters used in dynamic simulations accurately represent the generator excitation control system or plant volt/var control function behavior when assessing Bulk Electric System (BES) reliability.
MOD-027-1 verifies that the turbine/governor and load control or active power/frequency control1 model and the model parameters, used in dynamic simulations that assess BES reliability, accurately represent generator unit real power response to system frequency variations.
These models are necessary to support reliability analyses of the transmission system. According to the standard, PJM must develop data requirements, reporting procedures and schedules for the generation owners to support the building dynamics models. These models are then given to the NERC designee to support building interconnection-wide models.

Data Requirements & Procedure
Compliance bulletin, CB-016 PDF provides the information generation owners can request, the requirements to provide data and the required submission method. This is a living document that can be updated to meet PJM’s needs or NERC designee requirements.
Guidance for Preparing for Data Submittals PDF
Generator Owners must request and submit the dynamic modeling through PJM's Planning Community tool by creating a case as required for R1 information requests and R2 model submittals. PJM requires a separate case for MOD-026 and MOD-027 model submittals. PJM will provide its evaluation results in the case.
Planning horizon models are necessary to support reliability analyses of the transmission system. According to the MOD-032 standard, PJM must develop data requirements, reporting procedures and schedules for the transmission owners, generation owners and other stakeholders in its footprint to support the building of steady state, dynamics and short circuit models. These models are then given to the NERC designee to support building interconnection-wide models.

Data Requirements & Procedure
To comply with Requirement 1 of NERC standard MOD-032-1, PJM has developed the PJM MOD-032 Data Requirements and Procedures PDF. The document notes the information that transmission owners, generation owners and load serving entities must provide, as well as the required submission methods and schedules. This is a living document that can be updated to meet PJM’s needs or NERC designee requirements.
Planning Center is PJM’s planning tool, which is made up of a suite of modules that allow members to work with data required for long-range planning studies.
The Gen Model module lets generation owners upload the required data for NERC’s MOD-032-1 standard.
Model on Demand is a tool for collecting transmission owner data submissions for MOD-032-1. To request access to Model on Demand or get more information, email MODemail@example.com.
