Eastern Renewable Generation Integration Study
-
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.

Western Wind and Solar Integration Study
-
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.

Hawaii Solar Integration Study
-
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.

Meeting Renewable Energy Targets in the West at Least Cost: The Integration Challenge
-
This report, commissioned by the Western Governors’ Association in the United States, provides an assessment of system operational measures that could reduce costs of wind and solar integration to the end-users. The report identifies challenges to adopting these measures and recommendations for action at the state level. Especially useful are the high-level and accessible explanations of these operational measures.

Wind Integration: International Experience, WP2: Review of Grid Codes
-
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.

Analysis of Indian Electricity Distribution Systems for the Integration of High Shares of Rooftop PV
-
India has a target of 40 GW of rooftop PV by 2022. The study intends to provide an overview of the characteristics of the Indian power system and its challenges with regard to a significant increase in rooftop PV, as well as a template for distribution companies on how to manage rising PV shares, which studies to conduct and which technology options to select.
