Compensation Devices to Support Grid Integration of Variable Renewable Energy

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".
