Integration of renewable energy in the Latvian grid

As solar and wind installations have rapidly expanded in Latvia and neighboring countries in recent years, the challenge of efficiently integrating renewable energy into the grid has emerged. To address this, the Latvian TSO AST commissioned Artelys to conduct a study aimed at assessing the grid’s renewable hosting capacity and evaluating the potential benefits of Grid Enhancing Technologies (GETs) for facilitating renewable integration. The study performed simulations with the open-source optimal power flow tool PowSyBl Metrix. The findings highlight that GETs could increase the grid’s Renewable Energy Sources (RES) hosting capacity by up to 40%, without requiring major grid expansion projects. The study concludes by providing a set of recommendations in relation to integration of Innovative Grid Technologies in the Latvian grid.
