Investigation of Generator Ramp Rates in High Renewable Penetration Systems using an Academic New York Network Model

This paper presents an Academic Model of the NYISO transmission system that mimics key features of the New York network on a smaller scale without the use of confidential information. A day-ahead and real-time Market Model is developed using MatPower. Real time dispatch and commitment engines operate on 5 and 15 minute time scales, respectively. Startup notification and the ability to curtail renewable resources are modeled. Simulations show the effects of doubling steam unit ramp rates on two days in both low and high renewable penetration scenarios.
