This white paper provides guidance for Mexico’s electricity system planners and other stakeholders on how to develop a comprehensive grid integration study. Drawing from the IEA’s Expert Group Report on Recommended Practices 16. Wind Integration Studies, this report contextualizes recommendations and best-practices specifically to support Mexico’s goals of increasing the contribution of RE to the nation’s electricity supply. Throughout the report, the authors provide expert insights into how Mexico can prioritize near-term versus long-term data collection, analyses, and other actions to understand and address the impacts of higher wind and solar penetration levels associated with Mexico’s 35% by 2024 RE goal.

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 Western Wind and Solar Integration Study examines the benefits and challenges of integrating significant wind and solar energy to the Western Interconnection, which covers the power system operated by the WestConnect group of utilities in Arizona, Colorado, Nevada, New Mexico and Wyoming. The study consists of three phases. Phase 1 investigates the operational impacts of increasing the penetration of wind, solar photovoltaics (PV), and concentrating solar power to up to 35% in 2017. Phase 2 analyzes the wear-and-tear costs and emissions impacts associated with increased cycling by conventional generation due to wind and solar integration. Phase 3 evaluates the transient stability and frequency response of the Western Interconnection under high penetration solar and wind scenarios and identifies ways to mitigate adverse impacts through transmission reinforcements, storage, advanced control capabilities, and other mechanisms.

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.

Initiated by the European Network of Transmission System Operators for Electricity (ENTSO-E), this study evaluates transmission-related challenges associated with four wind penetration growth scenarios (no wind growth from 2008 levels, best estimate of wind growth, optimistic but feasible growth, and growth when further grid enhancements are made beyond 2015). The study includes recommendations related to network finance, reinforcements, grid security and flexibility, consents, coordinated operation, grid code, network access rules, market development, offshore grids, and control of wind generation.

Developed in response to the ambitious RE targets established by the Hawaii Clean Energy Initiative, the Hawaii Solar Integration Study evaluates the operational impacts of high penetrations of solar PV (including both centralized and distributed PV) on the electricity grids of two Hawaiian islands: Maui and Oahu. The two islands provide examples of small power grids with differing levels of firm and RE capacity. The study examines variability, the ability to curtail power output, grid support, and load characteristics in the context of increasing variable RE on these systems. The technical reports underlying the summary are available here.

ISO New England (which serves as the regional transmission organization for the New England region of the United States) commissioned the New England Wind Integration Study to assess the operational, planning, and market impacts of integrating up to approximately 12GW of wind power. The study finds that wind energy could supply up to 24% of New England’s total annual electricity needs by 2020 if the system implements transmission upgrades.

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.

This study explores technologies that can provide control of active power output from wind power. The study assesses how active power control technologies impact production costs, wind power revenue streams, and the overall reliability and security of the power system. The authors find that wind turbines have great potential to provide automatic power controls. However, careful market and control system design will be needed to realize these benefits.

This report reviews grid interconnection codes that relate to the performance of wind turbines, as well as requirements that can validate wind farm and turbine performance. Also reviewed are modeling requirements for simulating the performance of wind farms in the power system. Specifically, the authors examine grid codes from the UK, Germany, Denmark, Spain, Texas, Canada, and Europe.
