Texas is among the leading states that are most quickly embracing renewable energy. As it champions the use of "clean" energy, significant environmental and economic benefits of renewables have been realized within Texas. This talk will present a high-level overview of the challenges encountered to reach such a high penetration level of renewable generation at ERCOT. These challenges are also complicated by the high-dimensional problem spaces unavoidable for a bulk power system and very strict computational time requirement demanded for real-time applications. Recent solutions developed at ERCOT have been focused on quantifying and mitigating the uncertainties and variations resulting from renewable resources and examining the impact of those inverter-based technologies over the grid dynamics. As a power grid such as Texas Interconnection is evolving quickly, it will continue to stimulate more innovations and make itself an ideal test bed for validating emerging technologies given its size and complexity in structure.
