Abstract
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). 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".

Publication Compensation Devices to Support Grid Integration of Variable Renewable Energy(World Bank, Washington, DC, 2019-07)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). 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".Publication Using Forecasting Systems to Reduce Cost and Improve Dispatch of Variable Renewable Energy(World Bank, Washington, DC, 2019-07)This technical guide is the fourth 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). It provides guidance on the role and benefits of forecasting as a cost-effective operational solution to manage the uncertainty of VRE generation and facilitate the integration of larger shares of these resources in the energy mix. The guide focuses primarily on the types of forecasting methods and how physical and statistical models are used for developing short- to long-term forecasts. Technological advances in weather forecasting, together with better data on historical performance of renewable energy, allow significantly improved forecasting accuracy of VRE generation, which results in more efficient utilization. Examples from developing countries illustrate how the approach to forecasting varies depending on the country’s electricity market structure and requirements.Publication Integrating Variable Renewable Energy into Power System Operations(World Bank, Washington, DC, 2015-01)Wind and solar energy is a fast-growing share of the global energy mix. But integrating them into power-system operations requires significant adaptations to compensate for their variability. Solutions include increasing the amount of flexible generation within the system, combining, and dispersing variable resources to smooth aggregate output, expanding the transmission network, using smart technology to control supply and demand, and storing electricity.Publication Operating and Planning Electricity Grids with Variable Renewable Generation : Review of Emerging Lessons from Selected Operational Experiences and Desktop Studies(Washington, DC: World Bank, 2013-02-27)The development of wind-and solar-generating capacity is growing rapidly around the world as policy makers pursue various energy policy objectives. This paper will describe the challenges in integrating wind and solar generation, the lessons learned, and recommended strategies from both operating experience and integration studies. Case studies on the experience with wind and solar integration in China, Germany, and Spain are also included in this paper. The paper is organized as follows. First section summarizes worldwide wind and solar development, the challenges in integrating wind and solar generation, and some of the lessons learned from studies designed to evaluate the impact of higher levels of wind and solar generation and also from the operational experience in some countries with larger amounts of renewable energy. The second section summarizes some of the solutions for incorporating higher levels of wind and solar capacity into short-term system operations. This section also explains basic methodologies to implement system operations studies to understand the impacts of variability in system operation. The third section explains the contribution of variable renewables to long-term supply adequacy-commonly called 'firm' power-and the relationship of this to long-term reserves; it also explores how these issues can be incorporated into long-term planning or adequacy assessments. Overall, the variability of wind power generation adds to the variability on the grid in most time scales, and a key question that wind integration studies must address is whether there is enough existing capability on the grid to manage that increased variability, or whether new sources, such as new generation or increased levels of demand response, must be added to manage that variability.Publication Honduras(World Bank, Washington, DC, 2010-05)This report was prepared in response to a request by the government of Honduras for assistance in the preparation of a power sector strategy for the country. Specifically, the government asked for help in identifying the main issues in the power sector, and in addressing them through formulation of a clearly defined, achievable strategy. Left unresolved, these issues risk derailing the country's macroeconomic framework, potentially damaging the competitiveness of the country and its prospects for poverty reduction. The main issues to be analyzed in the study were identified at a workshop held on September 19, 2006, in Tegucigalpa, jointly with the Secretaria de Recursos Naturales y Ambiente (SERNA) and the Comision Presidencial de Modernizacion del Estado (CPME), and with the participation of representatives from the Empresa Nacional de Energia Electrica (ENEE), civil society, the private sector, Congress, public sector agencies, donors, utilities, and ministries. It was decided that the study would be divided into two components: (a) the first would identify and evaluate options on institutional reforms, particularly ENEE's restructuring and management, and securing electricity supply; and (b) the second would formulate a power sector strategy. Two reports will be prepared, with the second report to be finalized according to the timing of the government's decision. This first report analyzes the institutional and policy issues; financial and fiscal concerns; social aspects, such as tariffs and subsidies, and access to electricity; and investment requirements including the development of renewable resources. The report is divided into two parts. Part A presents a diagnostic of the electricity sector, including ENEE's financial performance, fiscal impacts, and reliability of supply, institutional and legal framework, pricing policy, and electricity coverage. Part B evaluates the options available to improve sector efficiency, ensure financial sustainability, promote the diversification of energy sources, and increase electrification coverage.
