Flexibility for Intermittent Generation Accommodation

2021
VPP Enerģētika projekts INGRIDO

The deliverable builds on the takeaways of D1.1 and assesses the flexibility requirements induced by intermittent generation sources, identifies prospective flexibility providers; it also expands the previous study on wind energy development by focusing on its potential and research in Latvia, also utilizing experimental measurement data and wind generation forecasts. The expected major rise in the installed wind energy capacities is identified as the main driver for increasing flexibility needs in the Baltic power system. The report has five main chapters. The first chapter explains the power system flexibility issue, its drivers and relation to wind and solar power production forecasting at various time horizons. The second chapter deals with various types of flexibility resources (generation, storage, demand-side, aggregation) and their utilization for power system balancing, congestion management, power system adequacy, black-start and power quality maintenance. The third chapter considers the technological development of wind turbines and projections regarding their installed capacity and the rising capacity factors. Special attention is given to wind production forecast inaccuracies in the Baltic states. The fourth chapter describes the expected efficiency of low-power wind turbines and their development potential in Latvia, also providing forecasts per regions of Latvia. Finally, the last chapter utilizes wind speed measurement data from meteorological sensors fitted to mobile phone network stations as a tool for studying the wind power potential at the height of 100 meters.
