Traditional Fossil Fuel Generators (FFGs) are incapable of providing Flexible Ramp Product (FRP) due to lower FRP market time frame, while modern FFGs are characterized by high ramping costs. Also, ramping support providence from FFGs enhance carbon emissions. Wind and solar FRP can reduce system imbalances, however, their ramping capabilities are highly uncertain and may not reliably fulfill System Ramping Requirement (SRR). This paper proposes a reliable and deliverable Zero Carbon Flexible Ramp Product (ZCFRP) using wind, solar and Variable Speed Pumped Hydro Power Plants (VSPHPPs). The reliability of the proposed ZCFRP depends on the estimation of accurate SRR, Renewable FRP (RFRP) availability, and generation/pumping capacity of VSPHPP. SRR and RFRP availability are estimated using copula theory. VSPHPP’s generation/pumping capacities are optimally modeled considering historical SRR and maximum possible RFRP variation. Delivery of the proposed ZCFRP is ensured by considering transmission line constraints. Dynamic ramping constraints are considered to reflect the practical characteristics of thermal generators. A case study shows that the proposed ZCFRP is beneficial to both system and ZCFRP providers (ZCFRPPs) by reducing dispatch costs and increasing revenue, respectively.
