CIM for Dynamics

Introduction

▪Dynamics simulates transient (sub-cycle) behavior of the grid

▪Required data includes:

– Individual dynamic behavior of each piece of equipment

– Connectivity and steady state electrical characteristics (EQ)

– Starting point steady state solution (TP, SV)

▪Dynamics models are shared

– Among transient analysis applications

– Among TSOs and ISOs

▪Background

– Creation of standard behavior models started in mid-1960s

– 100+ standard behavior models from IEEE and IEC

– Multiple defacto standard models

CIM for Dynamics – Status Update

▪Status

– 150+ standard models identified, documented and entered into UML

– Preliminary inclusion of Wind models - collaboration with IEC TC88

WG27 who are developing dynamic models

– UML-driven documentation strategy utilized

– In CIM16

– NWIP and CD being drafted by WG13

– Use planned by ENTSO-E and ERCOT

Test results ExcDC1A
