This technical guide is the first in a series of four technical guides on variable renewable energy (VRE) grid integration produced by the Energy Sector Management Assistance Program (ESMAP) of the World Bank and the Global Sustainable Electricity Partnership (GSEP).
... Exibir mais + It provides a general overview of the intrinsic characteristics of VRE generation, mainly solar PV and wind, what the main challenges are along with some recommendations for VRE technical specifications, applicable standards, and essential testing. The main focus of the document presents a detailed outline of the essential requirements for VRE integration into the power grid. The requirements differ for different levels of penetration but would require fundamental grid compliance requirements that must be reflected in any grid. This document provides these requirements along with recommendations of advanced VRE integration requirements that could be reflected in the power system operations with these VRE resources. The compliance with the technical requirements where applicable is validated through extensive series of interconnection studies which are further elaborated in "STUDIES FOR GRID CONNECTION OF VARIABLE RENEWABLE ENERGY GENERATION PLANTS – Technical Guide 3".

This technical guide is the second in a series of four technical guides on variable renewable energy (VRE) grid integration produced by the Energy Sector Management Assistance Program (ESMAP) of the World Bank and the Global Sustainable Electricity Partnership (GSEP).
... Exibir mais + It focuses on the main functionalities, differences and benefits of various compensation devices that can be employed to increase system transfer capacity, system stability, power quality and flexibility to cope with increasing penetrations of renewables in the system. The applications of FACTS devices are associated with four essential technical enhancements of system capacity, system reliability, power quality and system controllability. The application of the FACTS devices for these enhancements would depend on the system needs which would be identified and recommended through the power system studies during the interconnection process. Power system studies are further elaborated in "STUDIES FOR GRID CONNECTION OF VARIABLE RENEWABLE ENERGY GENERATION PLANTS – Technical Guide 3".

Integration of large-scale variable renewable energy (VRE) generation resources -- wind and solar -- into national grids has been gaining importance as costs of these technologies, especially that of solar, continues to fall rapidly.
... Exibir mais + However, there continues to be a lack of a framework to systematically analyze the role played by large-scale VRE integration for most developing countries. This study develops such a framework and applies it to analyze VRE policies in Bangladesh. The study uses a least-cost planning approach to assess the volume of solar and wind that can technically and economically be integrated in the power system, accounting for spinning reserve generation capacity requirements and adequacy of transmission capacity. The study shows that solar and wind can provide a significant share of the 13 to 21 GW of new capacity needed by 2025 to meet rapidly growing electricity demand, although most of it does not pass the cost/benefit test in the near term till 2022. Efforts are also required to cope with what otherwise would be a large and costly increase in on-demand ("spinning") reserve capacity. The analysis demonstrates how an investment strategy to cover peak demand, and prudent changes in system operational practices, allow for the system to provide the needed reserve capacity without a prohibitive increase in system costs. In addition, the study examines the adequacy of transmission capacity for the first large-scale solar and wind project in Bangladesh.
