Description:	Currently, the ramp rates on individual resources are ignored during Local Congestion. This leads to Dispatch Instructions that are impossible to adhere to, especially when every unit running for a QSE is getting a unit specific instruction. Although a QSE may ignore category 4 instructions, they must still follow the category 1. In the event that every unit running for a QSE in a zone is getting a category 4, they all make up the category 1. As a result of the ramp rates being violated, SCE cannot be followed, which puts a strain on frequency which leads to regulation and balancing instructions. Further, the QSE can potentially be penalized with imbalance charges for not keeping SCE at 0.
