This study prepared by the European Photovoltaic Industry Association (EPIA) aims to provide a holistic vision of how solar electricity will be integrated in the electricity system. The work involved interviewing several network operators, both at transmission and distribution level, so as to identify best practices and build recommendations on the basis of real-world experience. The identified challenges have been answered with existing and potential future solutions, making the best use of PV systems capabilities, which are today vastly underestimated.

This report describes the impact of wind power on the grid, methods to analyze the impact and approaches to mitigate the impact. Countries like Denmark, Germany and Spain, and regions within the United States that include Texas and Colorado have achieved high penetration of wind energy with modest changes to the grid. The key to high penetration of wind energy has been flexible grids, according to the authors. They outline the lessons learned and focus on their applicability to emerging wind energy markets.

This presentation introduces the value of the integrated grid.

This report summarizes the Next-Generation Wind and Solar Power study, which was carried out by the International Energy Agency (IEA) as part of its Grid Integration of Variable Renewables (GIVAR) programme. The report contributes to the work of the Multilateral Wind and Solar Working Group as part of the Clean Energy Ministerial. It focuses on the contribution that next-generation wind and solar power technology can make to transforming power systems around the globe when combined with advanced, system-friendly deployment strategies.

India has huge potential of renewable energy resources such as wind, solar, hydro etc. Most of the renewable installations are in the renewable potential rich states of Tamil Nadu, Karnataka, Andhra Pradesh, Gujarat, Maharashtra, Rajasthan Himachal Pradesh and Jammu & Kashmir. These states contribute more than 80 to 90% to the total installed renewable capacity in the country. Various policy initiatives and fiscal incentives have awakened interest in developing renewable generation plants.

This chapter examines policy drivers of battery electric vehicles (EVs) and plug-in hybrid EVs, the current and anticipated impacts on carbon emissions, as well as what potential role policy can play in enhancing the innovation system and market development around such vehicles in the future. The authors start with a policy review of key targets in the Nordic countries and the EU, up to 2030, and they discuss to what extent they are consistent with industry and expert estimates of how the systems can grow.

This white paper summarizes the challenges to integrating increasing amounts of variable renewable energy, identifies emerging practices in power system planning and operation that can facilitate grid integration and proposes a unifying concept—economic carrying capacity—that can provide a framework for evaluating actions to accommodate higher penetrations of renewable energy.

Investment in the transmission sector faces technical, economic and regulatory challenges. Rising energy demands, increased renewable energy penetration into remote grid and deregulation of power industry necessitates the evaluation of these challenges prior to investment in the transmission sector. The authors of this analysis investigate these challenges and recommend possible solutions for the development of transmission sector.

This wind power forecasting system includes high-resolution and ensemble modeling capabilities, data assimilation, now-casting and statistical post-processing technologies. The system uses publicly available model data and observations as well as wind forecasts produced from an National Center for Atmospheric (NCAR)-developed deterministic mesoscale wind forecast model with real-time four-dimensional data assimilation and a 30-member model ensemble system, which is calibrated using an Analogue Ensemble Kalman Filter and Quantile Regression.

The authors of this study characterize power systems in Southeast Asian countries by (1) reviewing their current installed capacity, generation mix, demand/supply scenario and transmission infrastructure, (2) evaluating their energy policies/capacity addition plans with a view to determine the extent to which renewables would play a role in meeting future power requirements and (3) assessing their readiness to absorb planned renewable energy capacities into their power systems while maintaining grid stability and security.
