The All Island Grid Study represents a comprehensive assessment of the power system on the island of Ireland to accommodate significant renewable energy penetration (including variable RE as well as dispatchable RE resources) by 2020. The study is divided into four “workstreams:” resource assessment, portfolio screening study, dispatch study, network study, and costs and benefits. The results include the climate change and energy security impacts, as well as the investment costs, associated with the RE scenarios.

The Electricity Reliability Council of Texas (ERCOT) commissioned this study of the ancillary services requirements for its system to accommodate up to 15,000 MW of wind energy. The Study evaluates and makes recommendations related to the methodology used by ERCOT to determine ancillary service needs; estimates the impacts of wind generation on the costs of ancillary services; and identifies changes to procedures related to severe weather conditions. ERCOT re-evaluated—and largely validated—the results of this study in a 2013 update.

To enable informed decision-making and planning related to increasing levels of DPV, the Distributed Generation Interconnection Collaborative (DGIC) facilitates knowledge sharing among its members about DPV interconnection practices, research, and replicable innovations. While the Collaborative primarily works with utilities and other stakeholders in the United States, its website hosts a collection of presentations, webinars, and reports that provide more broadly applicable information and case studies on interconnection practices.

The 21st Century Power Partnership supports global power sector transformation. The Partnership has developed a curated, annotated resource library that provides reports, academic literature, case studies, and good practices to support distributed generation regulation in a variety of power system contexts. The library is organized around several topical areas: Ratemaking, Understanding Impacts, Interconnection, Alternative Business and Regulatory Models, Planning, and Case Studies.

This study analyzes the ability of the Eastern Interconnection of the United States, one of the largest power systems in the world, to accommodate high penetrations of wind and solar power. Using advanced modeling and computing techniques, the project team simulated the large-scale adoption of wind and solar energy at a temporal resolution up to 5 minutes. The study represents the cutting-edge of power system modeling, employing a high spatial resolution to include all synchronous components of the Eastern Interconnection. Results suggest that the Eastern Interconnection can reliably integrate upwards of 30% variable renewable energy in the power mix. However, meeting the 30% target will require increased balancing area coordination, incentives for transmission and generation to provide necessary ancillary services, and increased flexibility of traditional generators. In addition to the technical report, the full dataset as well as animations showing net interchange for two study scenarios are available for free download.

The Eastern Wind Integration Transmission Study examines the operational impact of up to 20-30% wind energy penetration in the Eastern Interconnection, one of the three synchronous grids in the contiguous United States. The study addresses a variety of issues related to wind energy and transmission development, including the costs, impacts, and enabling mechanisms (e.g., geographic diversity, forecasting, operating reserves) associated with significant wind penetration. A follow-on study, the Eastern Renewable Generation Integration Study, is anticipated to be released in winter, 2015.
