Resumen:

Various aspects of power system flexibility are evaluated within the multi-country study framework of IEA Wind Task 25. Grid components and actions which have been adopted for enhancing flexibility in different areas, countries, regions are addressed, as well as how Transmission System Operators, Independent System Operators, Utilities intend to manage variable generation in their operating strategies. A visual assessment to evaluate the diversity of flexibility sources, called a “flexibility chart”, is further developed to illustrate several flexibility parameters (e.g., hydropower, pumped hydro, gas turbine, combined heat and power, interconnection and battery) in a polygonal radar (fan-shaped) chart. This enhanced version of the Flexibility Chart is an !at-a-glance” and !easy-to-understand” tool to show how to estimate the potential of flexibility resources in a given country or area, and is accessible for non-technical experts. The Flexibility Chart 2.0 is also a useful tool to compare the past and future flexibility of a system. Comparing the historical change of flexibility resources may not only be helpful to discuss energy policy in regions with high installed variable renewable generation, but also to contribute to the discussion in other regions where renewables have not been widely adopted yet.

Resumen divulgativo:

Evaluación visual para mostrar la diversidad de fuentes de flexibilidad, denominada "gráfico de flexibilidad", permite ilustrar varios parámetros de flexibilidad (por ejemplo, energía hidroeléctrica, energía hidroeléctrica bombeada, turbina de gas, calor y electricidad combinados, interconexión y batería) en un gráfico radar poligonal (en forma de abanico).
